1. Heart Circulation

2. Circulation Through the Body
The heart functions as two separate pumps

3. Pulmonary Circulation
Oxygen-poor blood from the right side of the heart goes to the lungs.

4. In the lungs...
Carbon dioxide leaves the blood and goes into the alveoli of lungs. Oxygen is absorbed into the blood on red blood cells (hemoglobin)

5. Systemic Circulation
Oxygen-rich blood from the left side of the heart goes to the rest of the body.

6. After cycling through the body
Oxygen-poor blood returns to the right side of the heart and the cycle starts over.
