How does the human circulatory system work?
Biology
ScanSolve AI Answer
The circulatory system is a double loop: Pulmonary circuit: Right ventricle → pulmonary arteries → lungs (gas exchange: CO₂ out, O₂ in) → pulmonary veins → left atrium. Systemic circuit: Left ventricle → aorta → body (delivers O₂, picks up CO₂) → vena cava → right atrium. The heart beats ~72 times/minute, pumping ~5L of blood. Arteries carry blood FROM the heart (thick walls, high pressure). Veins carry blood TO the heart (valves prevent backflow). Capillaries: gas/nutrient exchange.
