Why do the circulatory systems of land vertebrates have separate circuits to the lungs and to the rest of the body? view available hint(s) why do the circulatory systems of land vertebrates have separate circuits to the lungs and to the rest of the body? the large decrease in blood pressure as blood moves through the lungs may prevent efficient circulation through the rest of the body. land vertebrates are bigger and require more tubing to reach all areas of the body. the circuits increase the amount of surface area available for the diffusion of gases and nutrients in the body. blood is pumped to the lungs to be oxygenated before being pumped to the rest of the body.

Explanation:

There are two types of circulation in mammals. The pulmonary circulation and the systemic circulation. As you might know, mammals use double circulation of blood.

The pulmonary circulation is the circulation of blood from the heart to the lungs.

While

The systemic circulation is the circulation of blood from the heart to other parts of the body.
