Imagine you are a red blood cell. You are in the heart at this moment, before that you were in the lungs.

How many organs have you passed through at least if you have been back in the heart 4 times? (number)

Outside of the heart

pulmonary vein

inferior vena cava

coronary vein

coronary artery

right atrium

aorta

pulmonary artery

Inside of the heart

semilunar valves

right ventricle

septum

left ventricle

heart valves

left atrium

You'll learn more about this in basics 4: excretion

portal vein

Systemic Circulation

In all the organs of the body, oxygen and nutrients are delivered, while carbon dioxide and waste products are absorbed.

In the intestines, liver, and kidneys, additional processes occur, which is why these are highlighted separately.

Pulmonary Circulation

Flows only through the lungs, where it absorbs oxygen and releases carbon dioxide.

Heart is shown schematically:

RA = right atrium

LA = left atrium

RV = right ventricle

LV = left ventricle

oxygenated

deoxygenated

lungs

Lungs

All other organs

LORD

Left side is oxygenated = LO

Right side is deoxygenated = RD

Heartbeat

cardiac pause                                      contraction of atria                     contraction of                                                                                                                                             ventricles       

Which order of events is correct?
c = contraction cp = cardiac pause

1. c atria > cp > c ventricle
2. c ventricle > cp > c atria
3. c ventricle > c atria > cp
4. cp > c ventricle > c atria
