The Structure of a Human Heart

Question 1

Aorta

Answer 1

The main artery that carries blood away from the heart to the body (oxygen)

Question 2

Pulmonary artery

Answer 2

Blood vessel that carries O2 poor blood from the right side of the heart to the lungs (de-oxygenated)

Question 3

Aortic Valve

Answer 3

three leaflet valve between the left atrium and ventricle. ( de-oxygenated)

Question 4

Mitral valve

Answer 4

two leaflet valve between the left atrium and ventricle (oxygenated)

Question 5

Left atrium

Answer 5

Receives oxygen-rich blood from the lungs and pumps it into the left ventricle. (oxygenated)

Question 6

Left ventricle

Answer 6

Pumps oxygen rich blood to the rest of the body via the aorta. ( oxygenated)

Question 7

Right ventricle

Answer 7

Pumps oxygen poor blood to the lungs. ( de-oxygenated).

Question 8

Tricuspid valve

Answer 8

Three leaflet valve between the right ventricle and the pulmonary artery.

Question 9

Right atrium

Answer 9

Receives oxygen-rich blood from the lungs and pumps it into the right ventricle (de-oxygenated blood)

Question 10

Pulmonary veins

Answer 10

Blood vessels that carry oxygen-rich blood from the lungs to the heart (oxygenated)

Question 11

Pulmonary valve

Answer 11

Three leaflet valve between the right atrium and ventricle.

Question 12

Superior vena cava

Answer 12

A major vein that carries blood from the upper body (head, chest, arms) to the heart

Question 13

Order the blood flows

Answer 13

Aorta –> body –> vena super cava inferior –> right atrium–> tricuspid valve –> right ventricle –> pulmonary valve –> lungs (drop CO2 pick up O2) –> pulmonary veins–> left atrium –> mitral valve (aka bicuspid valve) –> left ventricle –> aortic valve –aorta
