Transcript text: Which chamber of the heart contracts and sends blood into the pulmonary trunk? Left atrium Right ventricle Left ventricle

Solution

The answer is the second one: Right ventricle.

Explanation for each option:

Left atrium: This chamber receives oxygenated blood from the pulmonary veins and sends it to the left ventricle, not the pulmonary trunk.
Right ventricle: This chamber contracts and sends deoxygenated blood into the pulmonary trunk, which then carries it to the lungs for oxygenation. Therefore, this is the correct answer.
Left ventricle: This chamber pumps oxygenated blood into the aorta, not the pulmonary trunk.
IDON'T KNOWYET: This is not a valid anatomical option.

In summary, the right ventricle is responsible for contracting and sending blood into the pulmonary trunk.
