Blood Flow Pathways
Systemic Circulation
Path: Left Ventricle → Aorta → Body → Vena Cava → Right Atrium
Blood: Oxygenated to body, Deoxygenated return
Pulmonary Circulation
Path: Right Ventricle → Pulmonary Artery → Lungs → Pulmonary Veins → Left Atrium
Blood: Deoxygenated to lungs, Oxygenated return
Cardiac Physiology Facts
Cardiac Cycle Duration
A complete cardiac cycle takes approximately 0.8 seconds at 75 BPM, consisting of coordinated atrial and ventricular contractions and relaxations.
Heart Valves
Four one-way valves ensure unidirectional blood flow: Tricuspid (3 leaflets), Pulmonary (3 leaflets), Mitral/Bicuspid (2 leaflets), and Aortic (3 leaflets).
Pressure Gradients
Blood flows from high to low pressure areas. Left ventricle generates highest pressure (120 mmHg systolic) to pump blood through systemic circulation.
ECG Correlation
Electrical activity precedes mechanical events: P wave triggers atrial contraction, QRS complex triggers ventricular contraction, T wave occurs during ventricular relaxation.
