Why Are There Two Loops in the Circulatory System

There are two loops in the circulatory system; the first goes to and from the heart, visiting the lungs to collect oxygen and get rid of carbon dioxide. The other loop is significantly longer and goes to and from the heart, but travels all around the body in between.

Why does the circulatory system have two circuits?

Your circulatory system has two main circuits: the systemic circuit, which takes blood from the heart to the body, and the pulmonary circuit, which takes blood from the heart to the lungs. The purpose of the systemic circuit is to provide your cells with oxygen.

What are the two parts to the double circulatory system?

• the pulmonary circuit is between the heart and lungs.
• the systemic circuit is between the heart and the other organs.
