Q

What is the direction of blood flow starting from Superior and inferior vena cava?

A

Superior and inferior vena cava bring blood to RA and RV

RA and RV bring blood to pulmonary trick that separates into right and left pulmonary arteries

Right and left pulmonary arteries go to lungs

Right and left pulmonary veins bring blood from lungs to heart

Blood goes in to LA and LV into aorta

Then body

17
Q

What is the valve between the right atrium and ventricle?

A

Tricuspid Valve

Or

Right atrioventricular valve

18
Q

What is the valve between the Left atrium and ventricle?

A

Bicuspid valve

Or

Left atrioventricular valve

19
Q

What is the valve between the right atrium and pulmonary trunk?

A

Right semilunar valve

Or

Pulmonary semilunar valve

20
Q

What is the valve between the left ventricle and the aorta?
