Sagot :

When blood first reaches the lungs, it contains high levels of carbon dioxide. That is option A.

The pulmonary circulation

The pulmonary circulation is the part of the circulatory system that concerns the movement of blood between the heart and the lungs.

The steps include the entrance of blood from the systemic circulation into the right atrium. As the right atrium contracts blood moves through the right ventricle into the pulmonary artery.

From the pulmonary artery, the deoxygenated blood enters the lungs to be oxygenated.

Therefore, when blood first reaches the lungs, it contains high levels of carbon dioxide.
