cardiovascular Flashcards
1
Q
function
A
- provide adequate circulation of blood through body
- transport oxygen, nutrients
2
Q
arteries
A
- larger, thick walls
- carry blood away from heart into systemic circulation
3
Q
arterioles
A
- very small
- branches off from artery
- carries blood away from heart to tissues and organs
4
Q
capillaries
A
- smallest
- thin walls
- oxygen and nutrients from blood can travel through walls
5
Q
venules
A
- smallest veins
- receive blood from capillaries
6
Q
veins
A
carry blood towards the heart
7
Q
aorta
A
- biggest artery
- carries blood from heart to rest of the body
8
Q
vena cava
A
- biggest veins
- directly empty deoxygenated blood into hearts right atrium
9
Q
mitral valve
A
regulates blood flow from left atrium into left ventricle
10
Q
pulmonary valve
A
opens to allow deoxygenated blood to leave right ventricle and flow to lungs
11
Q
aortic valve
A
opens to allow blood to flow from left ventricle to aorta
- keeps blood flowing in correct direction
12
Q
tricuspid valve
A
controls flow of blood from right atrium to right ventricle
13
Q
pulmonary veins
A
transport oxygenated blood from lungs back to heart
14
Q
heart rate
A
number of contractions per minute
15
Q
cardiac output
A
amount of blood ejected from each ventricle every minute
