Flashcards in EX 2; Cardiovascular Health and Disease Deck (12):
1

Loss of blood causes immediate reductions in MAP, but compensatory responses in these two things quickly restore MAP

Cardaic output
TPR

2

At the capillary level, reduced MAP does what

increases absorption and reduces filtration to help "protect" blood volume

3

When looking at an hematocrit, what are the levels of the erythrocyrtes/plasma immediately after and 18 hours after a hemorrhage

immediately after; both erythrocyte and plasma decreased
18 hrs after; erythrocyte the same as immediately and plasma is above normal

4

What are five causes of hypotension

hemorrhage
allergic response
emotional response
decreased cardiac output
fluid loss

5

How does an allergic response initiate hyoptension

histamine release leads to vasodilation

6

How does emotional stress lead to hypotension

increased PS and decreased S can lead to vasovagal syncope (pass out)

7

What deficiency can cause a decreased cardiac output

myocardial infarction

8

This is any situation in which a decrease in blood flow to the organs and tissues damaging them.

shock;
hypovolemic
low resistance
cardiogenic

9

What equals the pressure at a given point

cardiac generate pressure plus pressure equal to the weight of the column of blood to the point measured

10

By assisting the return of venous blood to the heart, this mechanism on veins opposes the buildup of excessive lymphatic fluid

skeletal muscle pump mechanism

11

Dynamic adjustments in blood flow distribution during exercise result from changes in what

cardiac output and from changes in regional vasodilation and vasoconstriction
decrease in TPR

12

This variety of drugs is used to treat hypertension

β blockers
