Blood Flow Pathways Understanding blood flow is essential. The circulatory system operates through two main circuits: Pulmonary Circulation Blood is pumped from the right ventricle of the heart to the lungs via the pulmonary arteries. In the lungs, blood picks up oxygen and releases carbon dioxide. Oxygen-rich blood returns to the left atrium via pulmonary veins. Systemic Circulation Oxygenated blood is pumped from the left ventricle to the rest of the body through the aorta. Oxygen and nutrients are delivered to tissues; waste products are collected. Deoxygenated blood returns to the right atrium via veins, completing the cycle. The Heart's Structure and Function The heart is central to the circulatory system, with its chambers and valves ensuring efficient blood flow: Chambers: Right and left atria (receiving chambers), right and left ventricles (pumping chambers). Valves: Tricuspid, bicuspid (mitral), pulmonary, and aortic valves prevent backflow and maintain unidirectional flow. Blood Vessels and Their Roles Each type of blood vessel has a specific role: Arteries: Carry oxygen-rich blood away from the heart. Veins: Return deoxygenated blood to the heart. Capillaries: Microscopic vessels where exchange of gases, nutrients, and wastes occurs. Common Disorders of the Circulatory System 4 Cardiovascular Diseases Understanding common circulatory disorders is vital for health awareness.
