cardiovascular, immune, lymphatic, blood Flashcards
pathway of the blood through the body
a closed loop circulation between the heart and body tissue
pathway of blood through heart
Blood comes into the right atrium from the body,
moves into the right ventricle and is pushed into the pulmonary arteries in the lungs.
After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body’s tissues through the aorta.
pathway of blood through lungs
pulmonary circulation; a closed loop circulation b/w the heart and lungs for gas exchange
Heart
pumps blood throughout the circulation system
where is the atria
top of heart
where is the ventricles
bottom of heart
hematopoiesis
Stem cells in the bone marrow develop into different types of blood cells (hematopoiesis) which are rbcs, wbcs, and thrombocytes (platelets).
arteries
Arteries are blood vessels that carry blood AWAY from the heart
arterioles
tiny arteries that carry blood AWAY from heart
venules
tiny veins that carry blood TOWARD the heart
venae cavae
Venae cavae is the largest vein the body. (inferior and superior)
aorta
largest artery in body; in left ventricle; in neck
veins
carry blood TOWARD heart; carry co2 rich blood because they carry blood from LUNGS to HEART
myocardium
the muscular tissue of the heart.
pericardium
2 layer sac surrounding the heart; contains the epicardium and the parietal pericardium
epicardium
outer lining covering the heart
endocardium
inner lining of the heart
myocardium
the muscular tissue of the heart.
plasma
Plasma is the part of your blood that carries platelets, red blood cells and white blood cells around the body. It contains antibodies, known as immunoglobulins, which fight infection. Plasma makes up approximately 55% of your blood.
thrombocytes (platelets)
blood clot formation and tissue repair (located in the buffy coat after centrifuge)
spleen
left of abdominal cavity b/w stomach and diaphragm; largest lympathic organ in the whole body; destroys old RBCs, stores blood. Blood flows through the spleen to be cleansed of microogranisms
thymus gland
on top of aorta, behind the sternum and b/w the lungs; important role in development of body’s immune system from child to adult; shrinks in puberty and after is no longer that important
lymph
colorless tissue fluid full of lymphocytes and monocytes; collected extracurricular fluid that travels away from body tissue to heart in a one way system; is drained into cardiovascular system through ducts in the chest
lymph nodes
small spherical bodies composed of lymphoid tissue; filter lymph to keep bacteria etc from entering the blood
angioma
Blood vessel tumor (benign)
An angioma is a benign growth that consists of small blood vessels. These tumors can be located anywhere on the body. Some of the different types include spider angiomas and cherry angiomas.
angiostenosis
Narrowing of (blood) vessels
angioplasty
Repair of a vessel (usually blood vessel)
embolectomy
Embolectomy is a medical procedure that involves the surgical removal of an embolus, which is a blood clot or other foreign material that has lodged within a blood vessel, obstructing blood flow
arteriosclerosis
Arteriosclerosis is similar to atherosclerosis, but instead of fatty deposits hardening the artery walls, calcium deposits do so.
cardiomyopathy
Heart muscle disease
endocarditis
ndocarditis is an inflammation of the inner layer of the heart, the endocardium. It usually involves the heart valves.
ischemia
deficiency in blood flow caused by constriction or obstruction of a blood vessel
myocarditis
inflammation of heart muscle
pericarditis
inflammation of sac surrounding heart
polyarteritis
inflammation of many arteries
valvulitis
inflammation of heart valve
aneurysm
ballooning of a weakened portion of an arterial wall
angina pectoris
chest pain occurring when there is insufficient blood supply to the muscle
cardiac arrest
sudden stop of cardiac output and circulation; requires CPR
coronary artery disease
CAD; reduces blood flow through coronary arteries to myocardium that may progress to depriving heart tissue of insufficient oxygen and nutrients; caused by atherosclerosis
deep vein thrombosis
blood clot in a deep vein
fibrillation
quivering/unsteady heart movement, leading to arrhythmia
heart failure/congestive
HF/CHF; inability to pump enough blood through body to supply tissues & organs with nutrients and oxygen
peripheral artery disease
PAD; artery disease in arms & legs resulting in a narrowing of artery caused by atherscerosis
varicose veins
distended/torturous veins usually found in lower extremities
angioplasty
angioplasty = repair of a blood vessel
angioscope
instrument used to look at a blood vessel
aortogram
radiographic image of the aorta
arteriogram
radiographic img of the artery
echocardiogram
heart echo uses sound to listen to blood flow of heart
diastolic
ventricles relax/ bottom number
sphygmomanometer
instrument used to measure blood pressure
systolic
ventricles contract/ top number
atrioventricular
AV; relating to atrium and ventricles
cardiogenic
originating in the heart
lumen
Each type of vessel has a lumen—a hollow passageway through which blood flows.
occlusion
the blockage or closing of an opening, blood vessel, or hollow organ.
cardiopulmonary
heart-lungs
defibrillation
delivers an electrical shock across the chest, either by placing a pair of manual paddles on the chest or through the application of adhesive “hands-free” pads. Current defibrillators typically utilize a biphasic waveform that needs a lower energy level to achieve effective defibrillation.
vasoconstrictor
constricts blood vessels
vasodilator
widens blood vessels
embolism
state of a plug (blood clot or foreign material)
CBC
complete blood count; Complete blood count w/ differential (CBC w diff): Lab test for basic blood screening that measures various aspects of RBCs, WBCs, and thromocytes (platelets).
hemoglobin
Hemoglobin Hgb: blood test measuring amount of Hgb (protein in rbcs that carries O2) in blood
thymoma
thymus tumor
lymphoma
lymph tumor
splenomegaly
enlargement of the spleen
lymphadenitis
inflammation of the lymph nodes
lymphadenopathy
lymphdenopathy: disease of the lymph nodes (enlargement)
