Single Circulation in Fish
Similar to the circulatory system of the human body, a single system is responsible for nourishing and transporting oxygen to all fish. Only blood reaches the heart in a whole cycle of one circulatory system, except just after going through the body of this fish. The process of gases exchange happens in the gills, thus through them the blood from the heart is delivered (carbon dioxide is released and oxygen is absorbed).
The product of the circulatory system is the oxygenated blood which supplies all the organ of the body through the gills and returns to the heart again using the same organs. The blood is in a single circulation since it flow only once time through the heart.
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.
