6

ID: 2

Interventricular Septum

7

ID: 3

Right Ventricle

8

Describe: 1

Deoxigenated blood enters right atrium from superior and inferior venae cavae.

9

Describe: 2

Blood in right atrium flows through right AV (Tricuspid) valve into right ventricle.

10

Describe: 3

Contraction of right ventricle forces pulmonary valve open

11

Describe: 4

Blood flows through the pulmonary valve into pulmonary trunk.

12

Describe: 5

Blood is distributed by right and left pulmonary arteries to lungs, where it unloads CO2 and loads O2.

13

Describe: 6

Oxygenated blood returns from lungs via pulmonary veins to left atrium.

14

Describe: 7

Blood in left atrium flows through left AV (bicuspid) valve into left ventricle.

15

Describe: 8

Contraction of left ventricle forces aortic valve open.

16

Describe: 9

Blood flows through the aortic valve into ascending aorta.

17

Describe: 10

Blood in aorta is distributed to every organ in the body, where it unloads O2 and loads CO2.

18

Describe: 11

Deoxygenated blood returns to right atrium via venae cave.

19

Give a simple 6 step description of blood flow.

  1. Blood enters the right atrium through vena cavae.
  2. Blood travels through tricuspid valve into right ventricle.
  3. Blood travels through pulmonary valve out to the lungs via the pulmonary arteries.
  4. Blood returns through pulmonary veins to left atrium.
  5. Blood passes through bicuspid valve to the left ventricle.
  6. Blood passes through the aortic valve to the aorta.
