Study Notes

Functions of the Heart

Heart contractions adapt to match blood flow with changing metabolic needs during rest, exercise, and posture changes, ensuring adequate blood supply.
Heart contractions generate blood pressure, necessary for blood flow through blood vessels.
Heart valves secure one-way blood flow through the heart and blood vessels, preventing backflow.

Anatomy of the Heart

The cardiovascular system is comparable to a muscular pump with one-way valves and a network of large and small tubes (blood vessels) through which blood circulates.
The heart separates pulmonary and systemic circulations, guaranteeing oxygenated blood flow to tissues.
