The Heart, Part 1 - Under Pressure: Crash Course Anatomy & Physiology #25
Guided Notes
3 key concepts
- 1
The heart's main function is to maintain a pressure gradient to pump blood throughout the body.
- 2
The heart is enclosed in a double-walled sac called the pericardium, which includes the outer fibrous pericardium and the inner serous pericardium.
- 3
The two loops of blood circulation are the pulmonary loop, where blood gains oxygen in the lungs, and the systemic loop, where oxygenated blood travels to the rest of the body.
