Question

The pulmonary circulation conveys blood that is ______ in oxygen to the lungs before returning back to the ______ side of the heart.

Answer 1

The pulmonary circulation conveys blood that is low in oxygen to the lungs before returning back to the left side of the heart.

The pulmonary circulation

The circulatory system is divided into two main parts namely:

• pulmonary circulation and

• systemic circulation.

The pulmonary circulation involves the movement of blood between the lungs and the heart.

Blood from the systemic circulation returns to the right side of the heart where it is pumped through the pulmonary artery into the lungs to be oxygenated.

After oxygenation has taken place in the lungs, the blood returns to the left side of the heart through the pulmonary veins.
