Perfectly

The artery walls are strong, tough, and tense to withstand pressure demands. Arteries contain elastic fibers, which allow their walls to stretch with systole and recoil with diastole. Arteries also contain muscle fibers (vascular smooth muscle, or VSM), which control the amount of blood delivered to the tissues. The VSM contracts or dilates, which changes the diameter of the arteries to control the rate of blood flow.

Femoral artery

The femoral artery travels down the thigh. At the lower thigh, it courses posteriorly; then it is termed the popliteal artery. Below the knee, the popliteal artery divides. The anterior tibial artery travels down the front of the leg on to the dorsum of the foot, where it becomes the dorsilis pedis. In back of the leg, the posterior tibial artery travels down behind the medial malleolus and in the foot forms the plantar arteries A)true B)false

VEINS

The course of veins parallels that of arteries, but the body has more veins and they lie closer to the skin surface. A)true B)false

The body has mor veins than arteries A)true B)false

The following veins are accessible to examination(VEINS)

Jugular Veins are palatable A)true B)false

Veins in the Arm. Each arm has two sets of veins: superficial and deep. The superficial veins are in the subcutaneous tissue and are responsible for most of the venous return. A)true B)false

Superficial veins are in the subcutaneous layer and is responsible for venous return A)true B)false

Veins in the Leg. The legs have three types of veins;

I. The deep veins run alongside the deep arteries and conduct most of the venous return from the legs. These are the femoral and popliteal veins. As long as these veins remain intact, the superficial veins can be excised without harming the circulation. A)true B) false

The deep veins run alongside the deep arteries and conduct most of the venous return from the legs. These are the femoral and popliteal veins. A)true B)false

2. The superficial veins are the great and small saphenous veins. The great saphenous vein, inside the leg, starts at the medial side of the dorsum of the foot. You can see it ascend in front of the medial malleolus; then it crosses the tibia obliquely and ascends along the medial side of the thigh. The small saphenous vein, outside the leg, starts on the lateral side of the dorsum of the foot, ascends behind the lateral malleolus, up the back of the leg, where it joins the popliteal vein. A)true B)false

2. The superficial veins are the great and small saphenous veins. The ________ saphenous vein, inside the leg, starts at the medial side of the dorsum of the foot.

VENOUS FLOW

Veins drain the deoxygenated blood and its waste products from the tissues and return it to the heart. A)true B)false

Veins carry deoxygenated blood and waste product to the heart A) true B)false

veins are a low-pressure system. A)true B) false

Veins is a low pressure system in the body A)true B)false

Because veins do not have a pump to generate their blood flow, the veins need a mechanism to keep blood moving.This is accomplished by (l) the contracting skeletal muscles that milk the blood proximally, back toward the heart; (2) the pressure gradient caused by breathing, in which inspiration makes the thoracic pressure decrease and the abdominal pressure increase; and (3) the intraluminal valves, which ensure unidirectional flow. Each valve is a paired semilunar pocket that opens toward the heart and closes tightly when filled to prevent backflow of blood

True

In the legs, this mechanism is called the "calf pump," or "peripheral heart." While walking, the calf muscles alternately contract (systole) and relax (diastole). In the contraction phase, the gastrocnemius and soleus muscles squeeze the veins and direct the blood flow proximally. Because of the valves, venous blood flows just one way-toward the heart. A) true B)false

Because venous pressure is lower, walls of the veins are thinner than those of the arteries. A)true B)false

Vein walls are thinner than artery walls A)true B)false

Veins have a larger diameter and are more distensible; they can expand and hold more blood when blood volume increases. This is a compensatory mechanism to reduce stress on the heart. Because of this ability to stretch, veins are called capacitance vessels. A)true B)false

Veins are more stretchable and expand to reduce the stress on the heart. A)true B)false

Efficient venous return depends on contracting skeletal muscles, competent valves in the veins, and a patent lumen. Problems with any of these three elements lead to venous stasis. A)true B)false

At risk for venous disease are people who undergo prolonged standing, sitting, or bedrest, because they do not benefit from the milking action that walking accomplishes. Hypercoagulable states and vein wall trauma are other factors that increase risk for venous disease. A)true B)false

Also, dilated and tortuous (varicose) veins create incompetent valves, wherein the lumen is so wide the valve cusps cannot approximate. This condition increases venous pressure, which further dilates the vein. Some people have a genetic predisposition to varicose veins, but obesity and pregnancy are increased risk factors. A)true B)false

obesity and pregnancy are increased risk factors. Of varicose veins A)true B)false

LYMPHATICS

Without lymphatic drainage, fluid would build up in the interstitial spaces and produce edema. A)true B)false

Without lymphatic system edema will build up A)true B)false

The vessels converge and drain into two main trunks, which empty into the venous system at the subclavian veins;

1. The right lymphatic duct empties into the right subclavian vein. It drains the right side of the head and neck, right arm, right side of the thorax, right lung and pleura, right side of the heart, and right upper section of the liver. 2. The thoracic duct drains the rest of the body. It empties into the left subclavian vein. A)true B)false

The functions of the lymphatic system are;

(1) to conserve fluid and plasma proteins that leak out of the capillaries, (2) to form a major part of the immune system that defends the body against disease, and (3) to absorb lipids from the intestinal tract. A)function of the lymphatic system B)function of vessel system

The immune system;

It accomplishes this by phagocytosis (digestion) of the substances by neutrophils and monocytes/macrophages and by production of specific antibodies or specific immune responses by the lymphocytes.

Immune system

CONTD......"LYMPHATIC"

Lymphatic capillaries start as microscopic open-ended tubes, which siphon interstitial fluid. The capillaries converge to form vessels. The vessels, like veins, drain into larger ones. The vessels have valves, so flow is one way from the tissue spaces into the bloodstream. The many valves make the vessels look beaded. A)true B)false

The flow of lymph is slow compared with that of the blood. Lymph flow is propelled by contracting skeletal muscles, by pressure changes secondary to breathing, and by contraction of the vessel walls themselves. A)true B)false

Lymph nodes are small, oval clumps of lymphatic tissue located at intervals along the vessels. Most nodes are arranged in groups, both deep and superficial, in the body. A)true B)false

Nodes filter the fluid before it is returned to the bloodstream and filter out microorganisms that could be harmful to the body. The pathogens are exposed to B and T lymphocytes in the lymph nodes. The lymphocytes mount an antigen-specific response to eliminate the pathogens.

Lymph nodes

With local inflammation, the nodes in that area become swollen and tender.

Lymph nodes

The superficial groups of nodes are accessible to inspection and palpation and give clues to the status of the lymphatic system:

>Cervical nodes drain the head and neck and >Axillary nodes drain the breast and upper arm. >The epitrochlear node is in the antecubital fossa and drains the hand and lower arm. >The inguinal nodes in the groin drain most of the lymph of the lower extremity, the external genitalia, and the anterior abdomjnal wall.

True

Related Organs

The spleen, tonsils, and thymus aid the lymphatic system A)true B)false

The spleen is located in the left upper quadrant of the abdomen. It has four functions: (1) to destroy old red blood cells; (2) to produce antibodies; (3) to store red blood cells; and (4) to filter microorganisms from the blood.

True

The tonsils (palatine, pharyngeal, and lingual) are located at the entrance to the respiratory and gastrointestinal tracts and respond to local inflammation.

True

The thymus is the flat, pink-gray gland located in the superior mediastinum behind the sternum and in front of the aorta. It is relatively large in the fetus and young child and atrophies after puberty. It is important in developing the T lymphocytes of the immune system in children. The B lymphocytes originate in the bone marrow and mature in the lymphoid tissue.

DEVELOPMENTAL COMPETENCE | Infants and Children

The lymphatic system has the same function in children as in adults A)true B)false

It is well developed at birth and grows rapidly until age 10 or 11 years. By age 6 years, the lymphoid tissue reaches adult size; it surpasses adult size by puberty, and then it slowly atrophies. It is possible that the excessive antigen stimulation in children causes the early rapid growth. A)true B)false

It is possible that the excessive antigen stimulation in children causes the early rapid growth. A)true B)false

DEVELOPMENTAL COMPETENCE | The Pregnant Woman

Hormonal changes cause vasodilation and the resulting drop in blood pressure A)pregnant woman B)aging adult

The growing uterus obstructs drainage of the iliac veins and the inferior vena cava. This condition causes low blood flow and increases venous pressure. This, in turn, causes dependent edema, varicosities in the legs and vulva, and hemorrhoids. A)true B)false

DEVELOPMENTAL COMPETENCE | The Aging Adult

Peripheral blood vessels grow more rigid with age, resulting in a condition called arteriosclerosis. This condition produces the rise in systolic blood pressure. A)aging adult B)infant

Arteriosclerosis rises systolic BP in the aging adult A)TURE B)false

Do not confuse this process with another one, atherosclerosis, or the deposition of fatty plaques on the intima of the arteries. A)true B)false

The Doppler Ultrasonic Stethoscope

Use this device to detect a weak peripheral pulse, to monitor blood pressure in infants or children, or to measure a low blood pressure or blood pressure in a lower extremity. A)The Doppler Ultrasonic Stethoscope B)none

The Doppler stethoscope magnifies pulsatile sounds from the heart and blood vessels. Position the person supine, with the legs externally rotated so you can reach the medial ankles easily. Place a drop of coupling gel on the end of the handheld transducer. Place the transducer over a pulse site at a 90-degree angle. Apply very light pressure; locate the pulse site by the swishing, whooshing sound. A)The Doppler Ultrasonic Stethoscope B)none

The Ankle-Brachial Index (ABI)

Use of the Doppler stethoscope is a highly specific, noninvasive, and readily available way to determine the extent of peripheral arterial disease (PAD). The patient is supine. Apply a regular arm blood pressure cuff above the ankle and determine the systolic pressure in either the posterior tibial or dorsalis pedis artery. Then divide that figure by the systolic pressure of the brachial artery. A)true B)false

In people with diabetes mellitus, the ABI is less reliable because of calcification (which makes their arteries non-compressible) and may give a falsely high ankle pressure. Thus the presence or severity of PAD may be underestimated. A)true B)false

An ABI of 0.90 or less indicates peripheral arterial disease (PAD): • 0.90 to 0.70-mild claudication • 0.70 to 0.40-moderate to severe claudication • 0.40 to 0.30-severe claudication, usually with rest pain except in the presence of diabetic neuropathy •

PROMOTING A HEAL THY LIFESTYLE: FOOT CARE Take Care of Your Feet!

Keeping blood flowing to your feet. • Walking is one of the best exercises for overall circulation. • When an individual is not able to walk, putting the feet up when sitting or lying down, stretching, wiggling toes, having a gentle foot massage, and warm foot bath are great alternatives. • Do not cross legs for long periods. • Do not smoke.

,true

Wearing shoes that fit and are comfortable. • The best time to measure feet is toward the end of the day, when feet tend to be the largest. • Individuals often have one foot that is larger than the other. It is recommended that shoes are fit to the larger foot. • Select shoes that are shaped like one's feet. The ball of the foot should fit comfortably into the widest part of the shoe. Toes should not be crowded. • For women, low-heeled shoes are safer and less damaging than high-heeled shoes

True

Keeping skin soft and smooth. • A thin coat of skin lotion over the tops and bottoms of one's feet help keep skin soft and smooth. However, this extra moisture should not go between the toes. • Use mild soap. • Be careful about adding oils to bath water. They can make your feet and the bathtub both very slippery.

Greater than normal force, then collapses suddenly. Aortic valve regurgitation, patent ductus arteriosus A)Water-Hammer (Corrigan) Pulse-3+ B)Pulsus Bigeminus Rhythm

Rhythm is coupled, every other beat comes early, or normal beat followed by premature beat. Force of premature beat is decreased because of shortened cardiac filling time. Conduction disturbance (e.g., premature ventricular contraction, premature atrial contraction) A)Pulsus Bigeminus B)Pulsus Alternans

Rhythm is regular, but force varies with alternating beats of large and small amplitude. When heart rate (HR) is normal, pulsus alternans occurs with severe left ventricular failure, which in turn is due to ischemic heart disease, valvular heart disease, chronic hypertension, or cardiomyopathy A)Pulsus Alternans B)Pulsus Paradoxus

Beats have weaker amplitude with inspiration, stronger with expiration. Best determined during blood pressure measurement; reading decreases (>10 mm Hg) during inspiration and increases with expiration. A common finding in cardiac tamponade (pericardia] effusion in which high pressure compresses the heart and blocks cardiac output); also in severe bronchospasm of acute asthma A)Pulsus Paradoxus B)Pulsus Bisferiens

ABNORMAL FINDINGS FOR ADVANCED PRACTICE

Peripheral Vascular Disease in the Arms

Episodes of abrupt, progressive tricolor change of the fingers in response to cold, vibration, or stress: (1) white (pallor) in top figure from arteriospasm and resulting deficit in supply; (2) blue (cyanosis) in lower figure from slight relaxation of the spasm that allows a slow trickle of blood through the capillaries and increased oxygen extraction of hemoglobin; (3) finally, red (rubor) in heel of hand due to return of blood into the dilated capillary bed or reactive hyperemia. A)Raynaud's Phenomenon B)edema

May have cold, numbness, or pain along with pallor or cyanosis stage; then burning, throbbing pain, swelling along with rubor. Lasts minutes to hours; occurs bilaterally. Several drugs predispose to the episodes, and smoking can increase the symptoms. A)Raynaud's Phenomenon B)Lymphedema

is high-protein swelling of the limb, most commonly due to breast cancer treatment. Surgical removal of lymph nodes or damage to lymph nodes and vessels with radiation therapy impedes drainage of lymph. Protein-rich lymph builds up in the interstitial spaces, which further raises local colloid oncotic pressure and promotes more fluid leakage. Stagnant lymphatic fluid increases risk for infection, delayed wound healing, chronic inflammation, and fibrosis of surrounding tissue. A)Lymphedema B)edema

Lymphedema after breast cancer is common (42%) 13 but usually mild. Early symptoms include self-reported sensations of a tired, thick, heavy arm, jewelry too tight, swelling, or tingling. Objective data include a unilateral swelling, nonpitting brawny edema, with overlying skin indurated. Early recognition is important because there is evidence to support effective interventions, such as complete decongestive physiotherapy, compression bandaging, and others. 18 Without treatment, lymphedema is chronic and progressive, which is psychologically demoralizing as a threat to body image and constant reminder of the cancer.

Peripheral Vascular Disease in the Legs

Chronic Venous Disease

Incompetent valves permit reflux of blood, producing dilated, tortuous veins. Unremitting hydrostatic pressure causes distal valves to be incompetent and causes worsening of the varicosity. Over age 45 years, occurrence is three times more common in women than in men. S: Aching, heaviness in calf, easy fatigability, night leg or foot cramps. 0 : Dilated, tortuous veins. A)Superficial Varicose Veins B)none

Acute Venous Disease

A deep vein is occluded by a thrombus, causing inflammation, blocked venous return, cyanosis, and edema. Virchow's triad is the classic 3 factors that promote thrombogenesis: stasis, hypercoagulability, and endothelial dysfunction.Cause may be prolonged bed rest; history of varicose veins; trauma; infection; cancer; and, in younger women, the use of oral estrogenic contraceptives. Requires emergency referral because of risk for pulmonary embolism. Note that upper-extremity DVT is increasingly common due to frequent use of invasive lines such as central venous catheters.

Peripheral Artery Disease

_________in the arteries are caused by atherosclerosis, which is the chronic gradual buildup of (in order) fatty streaks, fibroid and thrombus formation. This reduces blood flow with vital oxygen and nutrients. Risk factors for atherosclerosis include obesity, cigarette smoking, hypertension, diabetes mellitus, elevated serum cholesterol, sedentary lifestyle, and family history of hyperlipidemia. A)Occlusions B)anyerisum

An_________ is a sac formed by dilation in the artery wall. Atherosclerosis weakens the middle layer (media) of the vessel wall. This stretches the inner and outer layers (intima and adventitia), and the effect of blood pressure creates the balloon enlargement. The most common site is the aorta, and the most common cause is atherosclerosis. The incidence increases rapidly in men older than 55 years and women older than 70 years; the overall occurrence is four to five times more frequent in men. A)aneurysm B)heart failure
