Key concepts
3 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 divided into four chambers: two superior atria, which are low pressure areas, and two inferior ventricles that produce high pressures.
- 3
Arteries carry blood away from the heart, while veins carry blood back toward the heart.
