Flashcards in Circulatory ssytem Deck (24):
1

What is the function of heart valves

Prevent unwanted back flow of blood to the heart

2

What to the valves in the heart open and close in response to

Changes in pressure

3

What are the atrioventricular valves for

Preventing back flow of blood between arteries and ventricles (increased pressure)

4

What are the semilunar valves for

prevent blood flow when there is a drop in pressure

5

What is coronary circulation

Circulation of blood to the heart

6

Where do the coronary arteries branch from

Base of the aorta

7

Where does the right coronary artery supply blood to

Myocardium of right ventricle

8

Where does the left coronary artery supply blood to

Left Ventricle and posterior of heart

9

What is a reduction in blood flow called

ischaemia

10

What is vascular disease

The narrowing of the blood vessels which decreases performance

11

What is another word for hardening of arteries

atherosclerosis

12

Why do blood vessels narrow

Due to deposition of plaques as the body tries to repair damaged vessels

13

What is cardiac output

The volume of blood pumped per minute

14

What is peripheral resistance

The resistance to flow offered by the blood vessels

15

What blood pressure gives an indication of the strain on vessels when the heart is trying to pump

Systolic

16

What is optimal blood pressure

120/80

17

What is normal blood pressure

130/85

18

What blood pressure indicates stage 1 hypertension

140-159/90-99

19

What happens to SBP during exercise

It increases linearly with exertion levels

20

What happens to DPB during exercise

it can decrease due to vasodilation

21

What happens to DPB during exercise to individuals suffering from hypertension

It increases

22

What can cause a rapid increase in blood pressure

Valsalva effect

23

What are the long term effects of exercise on BP

Endurance and rhythmic training helps reduce BP over time
Weight training alone does not reduce BP

24

How does endurance training effect the Cardiovascular system

Increased stroke volume
stronger heart
lower resting heart rate
increased blood supply to tissue
Increased oxygen carrying potential
