What is Single Circulation?

What is Single Circulation?

Single circulation is a type of circulation commonly seen in fishes. This type of circulation is characterized when only one cardiac cycle is completed.

Points to note:

  • In single circulation, the blood passes through a single circuit – where blood is pumped by the heart to the gills for oxygenation, after which the blood flows to the rest of the body and back to the heart.
  • Animals such as fish are known to have single circulatory systems. Moreover, their hearts are two chambered- with just a single atrium and a single ventricle.
  • As a result, single circulation has a significant disadvantage – the oxygen delivery rate is slow and this consequently lowers the rate of metabolism.
  • Humans have a double circulatory system, where the blood travels in two distinct circuits.
