Question

what is double circulation​

Answer 1

Answer:

Explanation:

The human circulatory system has three key components: blood vessels, blood and the heart. It is called a double circulatory system because blood passes through the heart twice per circuit.

The right pump sends deoxygenated blood to the lungs where it becomes oxygenated and returns back to the heart.

The left pump sends the newly oxygenated blood around the body. By the time this blood returns to the heart, it has returned to a deoxygenated state.

Blood Passes Through The Heart Twice Per Circuit

Blood enters the heart

Deoxygenated blood from the body enters into the right atrium of the heart.

Blood pumped to lungs

This deoxygenated blood is pumped out of the heart and towards the lungs by the right ventricle.

Lungs oxygenate the blood

At the lungs, the deoxygenated blood exchanges carbon dioxide for oxygen. This is how it becomes oxygenated (contains oxygen).

Blood returns to the heart

Oxygenated blood returns to the left atrium of the heart.

Blood pumped to the body

This oxygenated blood is pumped out of the heart and to the body by the left ventricle.

Blood returns to the heart

The oxygenated blood gives its oxygen to body cells in exchange for carbon dioxide. The blood becomes deoxygenated and returns to the heart.

$\Large\mathcal\pink{DOUBLE \: CIRCULATION}$

Deoxygenated blood from the body tissues is poured into right atrium. Contraction of heart forces it into right ventricle. From right ventricle deoxygenated blood flows to the lungs through pulmonary artery.oxygenated blood from lungs is return into left atrium and then into left ventricle. The left ventricle forces the oxygenated blood to the whole body.thus, for making one complete round of circulation circuit around all body parts, the blood passes through the heart twice.

the pathway of blood from heart to the lungs and back to the heart is called pulmonary circulationand the pathway of blood from heart to the body and back to hurt is called system circulation this is known as double circulation of blood

$\Large\mathcal\orange{SINGLE \: CIRCULATION }$

Single circulation is the type of circulatory system that occurs in fishes in which the blood passes only one through the heart, in each complete circuit of the body compare double circulation “ single circulation a dictionary of biology

In single circulation there is no pulmonary circulation and there is only system circulation . These organism have two chambered heart and the blood is circulated one time from heart to the body
