Question | Answer |
3 main functions of blood | transport, regulation, protection |
composition of blood (2) | plasma and formed elements (blood cells) |
3 main plasma proteins | albumin, fibrinogen, globulins |
albumin | maintains osmotic pressure of blood, most abundant of plasma proteins |
fibrinogen | plasma protein, clotting factors, hemostasis, mfg in liver |
globulins | plasma protein, main component of antibodies, protects us from infection, acts as carriers for molecules like fat |
neutrophils | WBC granulocyte, segmented and banded, most important role is phagocytosis, 10-12 hours lifespan |
basophil | WBC granulocyte, releases histamine, contains anticoagulants (heparin), 3-7 days lifespan |
eosinophil | WBC granulocyte, releases chemicals that destroy certain parasites, 12 hours-3 days lifespan |
B-lymphocytes | WBC agranulocyte, originates in bone marrow |
T-lymphocytes | WBC agranulocyte, originates in thymus gland |
monocyte | WBC agranulocyte, macrophage |
thrombocytes (platelets) | smallest blood cell, life span 5-9 days, produced in red bone marrow as fragments of megakaryocytes. Function - prevent blood loss, essential to hemostasis |
hemostasis | process that stops bleeding |
3 events of hemostasis | 1. Blood vessel spasm. 2. Formation of a platelet plug. 3. Blood clotting/coagulation |
epicardium | outer layer of the heart, consists of squamous epithelial cells that overlie connective tissue |
pericardium | tough fibrous sac that surrounds/protects heart, made up of fibrous and serous pericardium |
myocardium | middle layer of the heart, consists of striated muscle fibers that cause heart contractions "myocardial infarction" affects this |
endocardium | innermost layer of heart, consists of endothelial tissue w/ small blood vessels and smooth muscle bundles |
chambers of the heart | right atrium - receives deoxygenated blood from superior and inferior vena cava. left atrium - gets oxygenated blood from 4 pulmonary veins (arteries) |
interventricular septum | separates the right and left ventricles |
function of heart valves | regulation, prevent backflow |
conductance vessels | arteries |
resistance vessels | arterioles |
the smallest and most numerous of all the blood vessels | capillaries |
blood vessels that carry deoxygenated blood back TO the heart | veins |
innermost layer of a blood vessel | tunica intima |
thick middle layer of blood vessel | tunica media |
tough outer layer of blood vessel | tunica adventitia |
primary function of large arteries | to conduct blood AWAY FROM the heart to the arterioles |
exchange vessels | capillaries |
capacitance vessels | veins, carry deoxygenated blood back TO the heart |
veins contain _________ that direct flow of blood in one direction | 1-way valves |
hepatic artery | carries oxygenated blood TO the liver |
hepatic portal veins | carries DEOXYGENATED BLOOD to liver for detoxification before returning to heart |
hepatic veins | carry DEOXYGENATED BLOOD from liver -> inferior vena cava |
great saphenous vein | longest vein in body, merges w/ femoral vein, usually harvested for CAVGs |
circle of Willis | where branches from internal carotid arteries and basilar artery form a circle of arteries at base of the brain, supplying the brain with blood |
aneurysms commonly occur where? | at the Circle of Willis |
right common carotid artery | arises from the brachiocephalic artery |
left common carotid artery | arises directly from aortic arch |
external carotid arteries | supply superficial areas of face/neck/scalp |
internal carotid arteries | extend to the front part to the base of the brain |
the blood flow to the stomach/spleen/pancreas/intestines/liver is referred to as...? | splanchnic circulation |
