Explanation:

${\huge{\bold{\underline{\underline{Answer:}}}}}$

Double circulation is a process during which blood passes twice through the heart during one complete cycle. This type of circulation is found in amphibians, reptiles, birds, and mammals. However, it is more prominent in birds and mammals as in them the heart is completely divided into four chambers – the right atrium, the right ventricle, the left atrium, and the left ventricle.

The movement of blood in an organism is divided into two parts:(i) Systemic circulation(ii) Pulmonary circulation
