Double Circulation of Blood
Double Circulation of Blood
Double Circulation is the type circulation in which blood flows through heart twice to complete a single cycle. This type of circulation system can be found in vertebrates like birds and mammals. As humans are also mammals, therefore, this type of circulation is also found in us.
The main organ of a blood circulatory system is its pump or we can say heart. Heart which is a muscular organ, pumps blood to different parts of the body.
The main difference is that the blood follows two routes - one for oxygenated blood and the other for deoxygenated blood. Hence, the name "double circulation'. Such type of blood circulation is called a closed vascular system.
Two types of circulation : Double Circulation in Human
1. Pulmonary Circulation :-
2. Systemic Circulation :-
Note : -
There are present some other fluid located in particular organs such as synovial fluid filled in the cavities of skeletal joints, viterous humour in the eye etc. These type of fluid are called as Non circulating fluids.
