Single Circulation Examples
The following are some of the examples of single circulation:
Single Circulation in Amphibians
Nearly all amphibians, especially frogs and toads, have one circulatory system. However, their hearts are slightly more complex than those of fish, with three chambers. Through deoxygenated blood flow, the body is brought into two atria, and oxygenated blood from the lungs is put into them. The next step after the mixing of the blood is the pumping of the blood by the ventricle to the body, where some of the oxygen is absorbed by the tissues before the circulation of the blood starts again.
Single Circulation in Reptiles
Almost all reptiles, among them lizards and snakes alike, have one-way circulation with a heart pumping blood in a three-chambered heart. Meanwhile, differences exist within reptiles as their heart has a partial separation of the ventricle, which permits at least some separation between oxygenated and deoxygenated blood. During this condition, there is a blood shift from body organs to the lungs, which helps in heightened oxygen delivery.

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.
