Question

The pulmonary veins conduct blood into the ___________, which pumps the blood into the left ventricle, which in turn pumps ____________ blood into the aorta and on to the many branches of the systemic circuit.

Answer 1

The pulmonary veins carry oxygenated blood to the left atrium, which sends it to the left ventricle; from there, it is pumped to the aorta and throughout the body.

Step-by-step explanation:

The pulmonary veins conduct highly oxygenated blood into the left atrium, which pumps the blood into the left ventricle, which in turn pumps oxygenated blood into the aorta and on to the many branches of the systemic circuit.

This pathway is essential in the pulmonary and systemic circuits of the circulatory pathway, ensuring that oxygenated blood reaches the tissues of the body and deoxygenated blood is transported to the lungs for gas exchange.
