Summary Introduction
To review:
Difference among systematic, pulmocutaneous, and pulmonary circuits.
Introduction:
Circulatory system includes a circuit of several blood vessels that are responsible for carrying blood and oxygen to different parts of the body. This circulation takes place with the help of three different types of circuits, namely, systematic, pulmocutaneous, and pulmonary depending upon the type of organism.
