Question

explain double circulation in human​

Answer 1

so here goes your answer

The majority of mammals (including humans) utilize a double circulatory system. This means we have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide.

Double circulatory systems are important because they ensure that we are giving our tissues and muscles blood full of oxygen, instead of a mixture of oxygenated and deoxygenated blood. While it may take a bit more energy than a single circulatory system, this system is much more efficient.

Answer 2

Answer:

in double circulation,the blood passes twice through the heart to supply to the body.this process is termed as double circulation.

Explanation:

double circulation involves two circulations;

1. systematic circulation:in this circulation blood completes its circulation from left ventricle to right auricle through body organs.
2. pulomonary circulation:in this,blood completes its circulation from right ventricle to left auricle through the lungs
