Card Set Information
arteries carry blood _______ ________ the heart
more muscular and elastic then other blood vessels
smallest branch of arteries are...
arterioles (which join with capillaries)
connect arterioles with venules
veins carry blood ________ _______ the heart
largest veins are the...
inferior and superion vena cava
thinner then arteries and have less muscle tissue
valves that keep blood from flowing back
what are the components of blood
erythrocytes, thrombocytes, leukocytes, plasma
components of plasma
proteins, fibrinogen, prothrombin, neutrients, electrolights, oxygen, carbon dioxide, metabolic waste products, hormones, enzymes
erythrocytes do what?
regulate oxygen and carbon dioxide through out the body
leukocytes do what?
thrombocytes do what?
normal cell count of erythrocytes
4.5-5.5 million per cubic mm
normal cell count of leukocytes
5,000-10,000 per cubic mm
normal cell count of thrombocytes
250,000-400,000 per cubic mm
engulf, ingest, and destroy bacteria
defend the body from allergic reaction by producing antihistamines
participate in the inflammatory response, produce histamine and heparin
phagocytize bacteria and foreign material (later response)
provide immunity for the body by developing antibodies
iron deficiency anemia
an anemia that results when there is an inadequate amount of iron to form hemoglobin in red blood cells
sickle cell anemia
a chronic, inherited anemia that results in the production of abnormal; crescent- shaped RBC's that carry less oxygen, break easily, and block blood vessels.
ballooning of an artery wall
a hardening or thickening of the arterial walls, resulting in loss of elasticity and contractility
a condition that occurs when fatty plaques are deposited on the wall of arteries. This narrows the arterial opening, which reduces or eliminates blood flow
congestive heart failure
a condition that occurs when the heart muscles don't beat adequately to supply the blood needs of the body. May involve either the right or left side of the heart
an inherited disease in which the blood does not clot (caused by the lack of a plasma protein required for the clotting process)
high blood pressure (usually greater than 140/90)
a disease of the bone marrow or lymph tissue that results in a high number of immature white blood cells
myocardial infarction (heart attack)
occurs when a blockage in the coronary arteries cuts off the supply of blood to the heart. the affected tissue dies
dilated, swollen veins that have lost elasticity and cause stasis (decreased blood flow)
