functions of blood in the cardiovascular system (3)
-transportation
-regulation
-protection
RBC
Erythrocytes, contain hemoglobin that carry oxygen and gases, formed in bone marrow
WBC
Leukocytes, protect body from invaders
platelets
Thrombocytes, fregmented cells, help in clotting blood
erythroproteins
what kidneys regulate to stimulate bone marrow to produce RBCs
plasma
watery liquid that contains dissolved substances
hemostasis
process of stopping bleeding
mechanisms that reduce blood loss (3)
-vascular spasm
-platelet plug formation
-blood clotting
hemophelia
in men, carried by mother, body doesn't produce Vitamin K
thrombosis
clot that can be dislodged
flow of blood
systemic capillaries-superior and inferior vena cava-R atrium-R ventricle-pulmonary trunk and pulmonary arteries-pulmonary capillaries-4 pulmonary veins-L atrium- L ventricle-aorta and systemic arteries-systemic capillaries
pericardium
triple layered sac that surrounds and protects the heart
fibrouse pericardium
inelastic, dense, irregular CT of the pericardium
serous pericardium
thinner, more delicate membrane that forms a double layer around the heart with parietal and visceral layers
parietal layer
outerlayer of serous pericardium
visceral layer
inner layer or epicardium of pericardium
heart wall layers (3)
-epicardium-outter layer
-myocardium-heart muscle that pumps the blood
-endocardium-inner most layer
Atrium
Ventricle
-recieves blood
-ejects blood
superior chambers of the heart (2)
Right and Left Atriums
inferior chambers of the heart (2)
Right and Left Ventricles
systole
phase of contraction in cardiac cycle of one heart beat
diastole
phase of relaxation in cardiac cycle of one heart beat
cardiac output
amount of blood ejected from Left Ventricle into aorta per minute
arteries
carry blood FROM heart TO tissue
types of arteries (3)
-elastic
-muscular
-arterioles
arterioles
smaller arteries that enter tissue and branch into capillaries
capillaries
where substance is exchanged between blood and body through walls to venules
venules
collect blood from capillaries and drain it into veins
veins
bring blood FROM tissue TO heart
layers of the blood vessels (4)
-tunica externa-outer
-tunica media-middle
-tunica interna-inner
-lumen-hole
venous return
volume of blood returned to the heart
baroreceptors
measure blood pressure
chemoreceptors
monitor blood acidity
Renin
hormone released by kidneys, increase total blood volume and Blood pressure
Epinephrine/norepinephrine
produced by adrenal glands to increase heart rate
antidiuretic hormone
causes vasoconstriction if there is a lot of blood loss, produced by hypothalumus and relaese from pituitary
parathyroid hormone
regulates circulation levels of calcium and phosphate ions in the blood, decrease blood pressure
calcitrol
hormone that is the active form of vitamin K, increases Blood pressure
blood transportation in cardio
-brings oxygen, nutrients, enzymes, and hormones to cells, takes co2 and waste away
blood regulation in cardio
regulates PH, adjusts body temp,ion balance
blood protection in cardio
protect against microorganisms and foreign bodies
vascular spasm
-vasconstriction of blood vessels
platelet plug formation
-platelets coagulate together
blood clotting
-coagulation when clot is gel
Right atriums gets...
deoxygenated blood
Left atriums gets...
oxygenated blood
Right ventricle pumps...
blood to lungs
Left ventricle pumps...
blood to arteries
