What is Single Circulation?
Single circulation is characterized by the fact that blood passes through the heart only once each cardiac cycle. Single circulation is found in fishes where the blood is pumped by the heart to the gills for oxygenation, after that it flows to the rest of the body and back to the heart.
Furthermore, their hearts are two-chambered, with only one atrium and one ventricle. As a result, single circulation has a significant disadvantage: the oxygen delivery rate is slower, and the rate of metabolism is reduced as a result. Humans have a double circulatory system, where blood travels in two separate circuits.

What is Single Circulation?
Single circulation is a circulatory system in which blood passes through the heart only once in the entire cycle. Single circulation is exhibited by fish where the heart pumps deoxygenated blood to the gills for oxygenation. The oxygenated blood then flows to the rest of the body and back to the heart.
Single circulation and double circulation differences lie in the number of times blood passes through the heart in each cycle. In this article, we will cover single circulation examples, diagrams and its features.
