Question | Answer |
5 blood vessel types in human body | arteries, arterolies,capillaries,venules, veins |
blood vessle type that carries blood back to heart | vein |
blood ves. type that carries blood to cap. | arterioles |
bl. ves. type carries blood away from heart | arteries |
blood ves. where gases are exchanged with bodys tissues | capillaries |
blood ves. type that capillaries empty into | venules |
blood in arterties | 02 |
blood arterioles | 02 |
blood in venules | CO2 |
blood in veins | CO2 |
capillaries blood | CO2 and 02 |
largest blo. ves in diameter | vein |
largest artery | aorta artery |
two tissue types found in walls of artery | smooth muscle and elstic tissue |
describe blood pressure in arteries vs. veins | arteris have low blood pressure |
walls of capillaries | sinusoids(leaky) |
what function of precapillary sphincters? where are they located | junction b/t capillaries and arterioles; control blood flow to capillaries |
what type of enviroment within the tissue will cause precap. to open/ close | low oxygen and nutrients to open; high amts to close |
venuous valves located | arms and legs |
function of venuous valves | prevent blood from falling backwards |
why are venuous valves needed? | bc there are low b.p in veins and also gravitational pull of arms and legs |
blood vol. of veins | 60-70 |
cap. blood vol | 5 |
systemic arteries blood vol. | 10-12 |
blood pressure means | force against inner walls of Blood vessles |
blood pressure avg. adult | 120/80 |
distolic | min presure |
systolic | max pressure |
why dont we take b.p from our veins | low pressure |
what artery is used to for blood pressure | brachial |
4 pressure points take pules | temporal, brachial, facial, radial |
stroke volume | amt of blood pumped per heart beat |
blood viscosity | blood thickness |
peripheral resistance | blood ves. are stretched |
blood vol. | amt of blood in body |
heart rate | beats per min |
baroreceptors located | arteries |
function of baroreceptors | dectect b.p changes in arteries |
3 pumps produce circulation in body | 1. heart2. respitory3.skeletal |
res. pump function | abdominals contract which sends blood back up |
skeletal muscle pump function | contraction of skeletal muclse squeeze blood back to heart |
4 life span changes within cardiovascular system | 1. heart enlargement2.death of cardiac muscle3. increase in adipose tissue of heart4. incrase in B.P |
why is the loss of cardiac cells thought of as irreversable | cells dont regenerate |
why does our heart enlarge as we get to old age | chordae tendone stretches and are loosen |
why does our heart rate decrease with old age | due to weight loss |
four chambers and valves found in the heart | R-al-ar-vl-vl-a-v , r-a-v, pul, and aortia |
