Blood entering the right ventricle in the heart during normal circulation goes to which structure next?

The blood that enters the right ventricle is deoxygenated and comes from the right atrium after returning from the systemic circulation. Once the right ventricle contracts, it pumps this deoxygenated blood through the pulmonary valve and into the pulmonary artery. From the pulmonary artery, the blood travels to the lungs. In the lungs, the blood picks up oxygen and releases carbon dioxide, which is vital for maintaining the body’s oxygen supply and removing waste gases. This process is known as pulmonary circulation.

Choosing the lungs as the next structure for the blood from the right ventricle is correct because it is critical for oxygenating the blood before it returns to the left side of the heart, where it will then be pumped into the systemic circulation to supply the rest of the body.
