what is double circulation .draw its flow chart
Answers
Here's is ur answer ^____^.
✔Double circulation:- .
It means the blood passes twice through the heart during each cycle .
Dear:( hope its helps ☺
Answer :
Double circulation is the circulatory system in higher vertebrates, including humans, where blood flows twice through the heart in two separate circuits - the pulmonary circuit and the systemic circuit. The pulmonary circuit delivers oxygenated blood to the heart and the systemic circuit delivers oxygenated blood to the body's tissues. This allows for efficient oxygenation of the body and supports the heart's own needs.
Explanation :
Double circulation is a term used in anatomy to describe the circulatory system in higher vertebrates, such as humans. In double circulation, blood flows twice through the heart in two separate circuits: the pulmonary circuit and the systemic circuit.
Here is a flow chart showing the double circulation in humans:
1.Blood from the body enters the right atrium of the heart.
2.Blood is pumped from the right atrium to the right ventricle.
3.Blood is then pumped from the right ventricle to the lungs, where it is oxygenated.
4.Oxygenated blood returns to the left atrium of the heart.
5.Blood is pumped from the left atrium to the left ventricle.
6.Blood is then pumped from the left ventricle to the rest of the body, where it delivers oxygen and nutrients to the tissues.
7.Deoxygenated blood returns to the right atrium, completing the pulmonary circuit.
8.The systemic circuit begins as deoxygenated blood is pumped from the right atrium to the right ventricle and then to the body.
9.Blood returns to the right atrium, completing the systemic circuit.
This double circulation allows for efficient oxygenation of the body's tissues and provides the heart with the necessary blood flow to support its own needs.
