Heart Structure:
Four chambers: 2 atria and 2 ventricles.
Valves ensure one-way blood flow.
Septum separates oxygenated and deoxygenated blood.
Cardiac Cycle:
One heartbeat cycle with systole (contraction) and diastole (relaxation).
Atria contract, filling ventricles.
Ventricles contract, pumping blood.
Controlled by electrical signals from the heart’s conduction system.
Efficient Blood Circulation:
Heart’s structure and cycle maintain blood flow.
Delivers oxygen, nutrients, and removes waste.
