Pulmocutaneous circulation

Pulmocutaneous circulation is an important part of the amphibian circulatory system. It helps direct blood to the skin and lungs, which is essential for breathing and absorbing oxygen through the skin. In amphibians, blood flows from the ventricle into a special artery called the conus arteriosus. From there, the blood moves into either the left or right truncus arteriosus.

These vessels then divide the blood into two pathways: the pulmocutaneous circuit and the systemic circuit. The pulmocutaneous circuit specifically sends blood to the lungs and skin, where it picks up oxygen and releases waste products. This process is vital for amphibians, as they rely on both lungs and their moist skin to breathe. Understanding pulmocutaneous circulation helps us learn how these animals stay alive and healthy in their environments.
