Study Notes
Functions of the Heart
- The heart adjusts its rate and force of contraction to match blood flow to the changing metabolic needs of the tissues during rest, exercise, and changes in body position.
- Heart contractions produce blood pressure, which is necessary for blood flow through the blood vessels.
- The heart's valves ensure one-way blood flow through the heart and blood vessels.
- The heart separates the pulmonary and systemic circulations, ensuring the flow of oxygenated blood to tissues.
Anatomy of the Heart
- The cardiovascular system can be compared to a muscular pump with one-way valves and a system of large and small tubes (blood vessels) through which the blood travels.
