Study Notes
Function of Myocardium
- Myocardium generates the necessary force to circulate blood throughout the body.
- Blood transport includes oxygen (O2), nutrients, carbon dioxide (CO2), and metabolic wastes.
- Oxygen-rich blood is sent to cells while CO2 and waste products are returned to the heart for removal.
Pulmonary Circuit
- Transports deoxygenated blood from the right ventricle to the lungs for gas exchange.
- Major components: pulmonary trunk, pulmonary arteries, lungs, and pulmonary veins.
- Delivers oxygenated blood back to the left atrium.
- Contraction of the right side of the heart drives blood through the pulmonary circuit.
Systemic Circuit
- Carries oxygenated blood from the left ventricle to body organs and tissues.
- Returns deoxygenated blood to the right atrium for reoxygenation.
- Key components include the aorta, arteries, arterioles, capillaries, venules, veins, and superior/inferior vena cava.
- Purpose is to supply O2 and nutrients to cells while removing wastes and CO2.
- Contraction of the left side of the heart propels blood through the systemic circuit.
