Circulatory System

Question 1

• Upper chambers that receive blood

Answer 1

Atria

Question 2

• Lower chambers that pump blood out of the heart

Answer 2

Ventricles

Question 3

• Ensure one-way blood flow

Include the tricuspid (right side), bicuspid/mitral (left side), pulmonary, and aortic valves.

Answer 3

Valves

Question 4

• Carry blood away from the heart, typically oxygenated (except pulmonary artery)

Answer 4

Arteries

Question 5

• Carry blood towards the heart, typically deoxygenated (except pulmonary veins)

Answer 5

Veins

Question 6

• Microscopic vessels where gas and nutrient exchange occur between blood and tissues

Answer 6

Capillaries

Question 7

• Blood flows from the heart to the body (left ventricle → aorta → systemic arteries → body tissues → veins → right atrium).

Answer 7

Systemic Circulation

Question 8

• Blood flows from the heart to the lungs for oxygenation (right ventricle → pulmonary arteries → lungs → pulmonary veins → left atrium).

Answer 8

Pulmonary Circulation

Question 9

The force exerted by blood on the walls of arteries. Normal is around 120/80 mmHg

Answer 9

Blood pressure
