Q

the atria

A

-has upper chambers
-holding chambers
-small, thin walled
-contracts minimally to push blood into ventricles

17
Q

tricuspid valve

A

-3 cusps
- AV valve between RA and RV

18
Q

Bicuspid valve

A

-2 cusps
- AV valve between LA and LV

19
Q

What happens when the bicuspid valve is open?

A

-blood flows from LA into LV
-aortic semilunar valve is closed
- tension on chordae tendinae is low

20
Q

semilunar valves

A
  • between ventricles and blood vessels
  • aortic (base of aorta)
    -pulmonary (base of pulmonary trunk)
21
Q

What happens when the bicuspid valve is closed?

A

-blood flows from LV into aorta
- aortic semilunar valve is open
- tension on chordae tendineae is high

22
Q

pulmonary circuit

A

collects blood from the body

23
Q

right side of the heart

A

-carries blood from heart to lungs
-blood deoxygenated
-02 poor
-CO2 rich

24
Q

right atrium

A

receives blood from superior vena cava, inferior vena cava, coronary sinus

25
Q

Superior vena cava

A

drains blood above diaphragm

26
Q

inferior vena cava

A

drains blood below diaphragm

27
Q

Coronary sinus

A

drains blood from the heart

28
Q

right ventricle

A

pumps blood into pulmonary trunk

29
Q

what is the pulmonary trunk?

A

splits into right & left pulmonary arteries

30
Q

pulmonary arteries

A

carry blood AWAY from the heart to the lungs

31
Q

what does the left side of the heart do?
(systemic curcuit meaning)

A
  • systemic circuit - receives blood from the lungs
  • carries blood from the heart to the body
    -blood is oxygenated
    -O2 rich / CO2 poor
    -much stronger, thicker muscle
32
Q

Left atrium

A

4 openings (pulmonary veins) that receive blood from the lungs

33
Q

Left Ventricle

A

-pumps blood into aorta
- thicker, contracts more forcefully, higher blood pressure than right ventricle has to get to body

34
Q

aorta

A

carries blood from LV to body

35
Q

Know blood flow through the heart

A
36
Q

Coronary arteries

A

-supply blood to heart wall
-originate from base of aorta

37
Q

Left Coronary artery

A
  • 3 branches
    -supply blood to the anterior heart wall and left ventricle
38
Q

right coronary artery

A
  • supply blood to right ventricle
39
Q

great cardiac vein

A

drains left side

40
Q

small cardiac vein

A

drains to right side

41
Q

middle cardiac vein

A

drains posterior

42
Q

coronary sinus

A

-receives both veins
- drains into RA
