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 by generating high hydrostatic pressure to pump blood out and low pressure to bring it back in.
- 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 superior chambers of the heart are called atria, which are low pressure areas, while the two inferior chambers are called ventricles, which produce high pressure.
