Question

what is double circulation?​

Answer 1

$\huge\underline\mathfrak{Answer :-}$

Hey,

• It is called a double circulatory system because blood passes through the heart twice per circuit. The right pump sends deoxygenated blood to the lungs where it becomes oxygenated and returns back to the heart. The left pump sends the newly oxygenated blood around the body.

• Double circulation is important to keep the oxygenated and deoxygenated blood separate from each other in the body and prevent their mixing. Such separation allows a highly efficient supply of oxygen to the body.

Answer 2

Answer:

A type of blood circulation system in which the blood flows through the heart twice. In this type of circulation, the pulmonary circulation is separate from the systemic circulation.

Supplement

In this circulation, the heart consists of: the right side that pumps deoxygenated blood into the pulmonary section and the left side that pumps oxygenated blood into the systemic circulation. This is common among mammals and birds. This is in contrast to animals that have only one circulation system such as fish.
