Question
How does the blood return to the heart from the lungs?through the pulmonary valvethrough the pulmonary veinsthrough the pulmonary arterythrough the aorta
Solution
The blood returns to the heart from the lungs through the pulmonary veins. Here's a step-by-step explanation:
- Oxygen-depleted blood from the body enters the heart through the superior and inferior vena cava into the right atrium.
- The blood then moves into the right ventricle, which pumps it out through the pulmonary artery.
- The pulmonary artery carries the blood to the lungs, where it picks up oxygen and releases carbon dioxide, a process known as gas exchange.
- The now oxygen-rich blood returns to the heart via the pulmonary veins, entering the left atrium.
- The blood then moves into the left ventricle, which pumps it out through the aorta to the rest of the body.
