Cardiovascular Hemodynamics

Myogenic muscular organ responsible for systemic and pulmonary circulation via coordinated rhythmic contractions.

Key Metrics & Data

• Mean Arterial Pressure (MAP): ≈ 70-110 mmHg.
• Cardiac Output (CO): SV × HR ≈ 5.0 L/min at rest.
• Healthy Ejection Fraction (EF): 55-70%.

Real-World Example

During ventricular systole, Purkinje fiber depolarization induces isovolumetric contraction, exceeding aortic pressure to force the semilunar valves open.
