What is meant by the term 'double circulation of blood
in mammals? What is diastole?
Answers
Answer:
the circulation which enters twice in the heart is know as double circulation
Explanation:
the phase of the heartbeat when the heart muscle relaxes and allows the chambers to fill with blood is known as diastole
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.
Diastole and systole are two phases of the cardiac cycle. They occur as the heartbeats, pumping blood through a system of blood vessels that carry blood to every part of the body. Systole occurs when the heart contracts to pump blood out, and diastole occurs when the heart relaxes after contraction.
