Answer 1

[AI-generated answer — Bot]

1. Oxygen-rich blood flows from the lungs to the left atrium of the heart.

2. The left atrium contracts, pushing the blood into the left ventricle.
3. The left ventricle then contracts, forcing the oxygen-rich blood out of the heart through the aorta.
4. The aorta and its branches carry the blood to the body's organs and tissues, delivering oxygen and nutrients.
5. In the organs and tissues, the oxygen-poor blood picks up carbon dioxide and other waste products.
6. The oxygen-poor blood returns to the right atrium of the heart via the superior and inferior vena cava, where the cycle begins again.
