Unit 3 Flashcards
Which artery does not directly supply the heart with blood ?
Carotid artery
What blood vessels are involved in blood flow either two or from the brain 
Jugular vein, carotid artery 
What are the characteristics of the cardiac muscle?
Striated, many mitochondria and involuntary
A condition caused by increased blood pressure and weaken blood vessel valves leads to swelling in the extremities
Varicose veins
Thick multicellular walls
Delivers blood from the heart to the body
Returns oxygen rich blood from the lungs back to the heart 
Arteries
Thin flabby walls with a wider diameter
Has valves to push blood from the extremities back to the heart
Veins
Single cell layer thick
Involved in gas exchange and nutrient waste exchange
Capillaries
Where is the brachial artery found?
Upper arm or humerus area
Where is the radio artery?
Some side of the lower arm
Where are the digital arteries?
Each finger of the hands
Where is the femoral artery?
Thigh region of the leg
Where is the popliteal artery?
Back of the knee
Where is the subclavian artery?
Underneath the collarbone
Where is the common iliac vein?
Pelvis region 
Where is the posterior tibial vein?
Ankle region 
Pressure is the audio wall when the ventricles are contracting
Systole
What instrument is used to measure arterial blood pressure?
Sphygmomanometer
What factors will cause an increase in blood pressure?
High levels of cholesterol
LDL
Being overweight
Normal blood pressure
Less than 120 less than 80
Hypertension
Greater than 140 greater than 90
Pre-hypertension
120 to 129 less than 80
What can cause a PAD
Plaques, reducing blood fall to extremities 
Eating foods high and saturated fats
Smoking
Normal ABI range
.90
What is tachycardia?
Increased heart rate for a variety of reasons
What is arrhythmia?
Condition where the heartbeat is a regular
What does the P-wave represent?
Represents the depolarization of both atria 
What does the QRS complex represent?
Combination showing ventricle depolarization
What does the t wave represent?
Represents the repolarization of both ventricles
Systemic loop
Oxygenated blood is pumped from the left ventricle to the aorta and beyond 
What is the larynx
The Voice box and sits superior to the trachea
Alveoli
Thin air sack that are wrapped in capillaries or gas exchange occurs 
Diaphragm
Don’t shave the muscle that moves upward during inspiration and downward during expiration
Why do the rings of cartilage cover the front 2/3 of the trachea
To allow for the movement of food through the esophagus
Where are the lungs housed?
Thoracic cavity
Where are the lungs housed?
Thoracic cavity
What is the movement of molecules from an area of high concentration to an area of low concentration?
Diffusion 
Abnormal self growth can block airways leading to shortness of breath
Lung cancer
Leads to irritation and buildup of mucus in the lungs
Common cold
Tissue gets thick and stiff, scarring the lungs, and preventing gas exchange
Pulmonary fibrosis
Airways become inflamed and narrowed muscles tighten, and wheezing is often observed
Asthma
Air collects in the spaces between lung tissue layers, pressure built-up prevents lung expansion
Punctured lung
Step one
The intercostals lift the rib cage and the diaphragm lowers decreasing the pressure inside the long
Step two 
Oxygen enters the upper respiratory tract moves through the bronchi, and then the bronchioles
Step three
Oxygen enters the alveoli and passes into the bloodstream through capillaries
Step four
Carbon dioxide moves from the bloodstream into the alveoli through capillaries
Step five
Carbon dioxide moves from the lower respiratory tract into the upper respiratory tract and then exits the body 
Symptoms of asthma
Wheezing
Shortness of breath
Chest tightness
Coughing
What does a low pulse ox levels mean?
Less oxygen is being distributed to tissues
What does the FEV rates referred to
Forcible inhalation volume of air during a respiration cycle
Title volume
Volume of air from a maximum inhalation, followed by a maximum exhalation
