Term
| Mean arterial pressure is directly related to |
|
Definition
| cardiac output (x) resistance in arterioles |
|
|
Term
| if cardiac output rises without a change in resistance.. |
|
Definition
| mean arterial pressure rises because there is more blood flow into the arterial system than out |
|
|
Term

|
Definition
|
|
Term
| if the blood volume falls.. |
|
Definition
| the kidneys conserve water and increased sympathetic activity causes vasoconstriction and increased heart rate |

|
|
Term
|
Definition

|
|
Term
|
Definition
blood volume increase
blood pressure increase
which triggers
a fast response or a slow response |
|
|
Term
|
Definition
cardiovascular to
vasodilation or cardiac output
which both lead to low blood pressure |
|
|
Term
|
Definition
kidneys which leads to
excretion of fluid
which leads to
lower blood pressure |
|
|
Term
| resistance is indirectly proportional to |
|
Definition
|
|
Term
|
Definition
| influenced by systemic and local control mechanisms |
|
|
Term
|
Definition
central nervous system
mantain mean arterial pressure
govern blood distribution for homeostatic needs |
|
|
Term
|
Definition
| metabolic needs of the tissue determine the blood flow |
|
|
Term
|
Definition
| as more blood is needed the resistance is decreased by dilating the ateriole, accomplished by paracrines |
|
|
Term
|
Definition
| influence blood pressure by acting directly on the aterioles and altering autonomic reflex control |
|
|
Term
|
Definition
| is controlled by tonic release or norepinefrin |
|
|
Term
| norepinefrin release increase |
|
Definition
|
|
Term
| norepinefrin release decrease |
|
Definition
|
|
Term
| when precapillary sphincters are relaxed |
|
Definition
| blood flows through all capillaries in the bed |
|
|
Term
| if precapillary sphincters constrict |
|
Definition
| blood flow bypasses capillaries complementary and flows through metarterioles |
|
|
Term
| bone marrow, liver, and spleen.. |
|
Definition
| have sinuoids instead of capillaries |
|
|
Term
| exchange by paracellular pathway |
|
Definition
| in between endothelial cells |
|
|
Term
| exchange by transendothelial transport |
|
Definition
|
|
Term
| large proteins are transported by |
|
Definition
|
|
Term
|
Definition
| mass movement of fluid between blood/interstitial fluid as results of hydrostatic or osmotic pressure |
|
|
Term
|
Definition
| fluid movement into capillaries |
|
|
Term
|
Definition
fluid movement out of capillaries
caused by hydrostatic pressure
net filtration at arterial end |
|
|
Term
|
Definition
| hydrostatic pressure - colloid osmotic pressure |
|
|
Term
|
Definition
| forces fluid out of capillary |
|
|
Term
| colloid pressure of proteins within the capillary |
|
Definition
| pulls fluid into the capillary |
|
|
Term
|
Definition
returns fluid/proteins filtered out of capillarieds to circulatory system
picks up fat absorbed at the small intestine and transferd it to the circulatory system
filter for pathogens |
|
|
Term
|
Definition
| coordinates the reflex control of blood |
