Deoxygenated blood from various parts of the body is collected by___
Answers
Deoxygenated blood leaves the heart, goes to the lungs, and then re-enters the heart; Deoxygenated blood leaves through the right ventricle through the pulmonary artery. From the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
Answer:
The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium. The pulmonary artery carries deoxygenated blood from the right ventricle into the lungs for oxygenation.
Key Points
Five great vessels enter and leave the heart: the superior and inferior vena cava, the pulmonary artery, the pulmonary vein, and the aorta.
The superior vena cava and inferior vena cava are veins that return deoxygenated blood from circulation in the body and empty it into the right atrium.
The pulmonary artery carries deoxygenated blood from the right ventricle into the lungs for oxygenation.
The pulmonary veins carry oxygenated blood from the lungs into the left atrium where it is returned to systemic circulation.
The aorta is the largest artery in the body. It carries oxygenated blood from the left ventricle of the heart into systemic circulation.
The aorta has many subdivisions that branch off into smaller arteries. These subdivisions are the ascending and descending aorta, the aortic arch, and the thoracic and abdominal aorta.
Key Terms
pulmonary arteries: The arteries that take deoxygenated blood away from the right side of the heart and into the capillaries of the lungs for the purpose of gas exchange.
aorta: The great artery which carries the blood from the heart into systemic circulation.
venae cavae: The two large vessels, the superior and inferior vena cava, that bring deoxygenated blood from systemic circulation to the heart.
