Question

Explain significance of double circulation

Answer 1

The double circulation is a circulation which completes two routes or phases in the whole human body, it includes, systemic circulations and pulmonary circulations.

1) Systemic Circulation: The flow of oxygenated blood from the left ventricle of heart to all parts of the body and deoxygenated blood from various parts of the body to the right atrium is called as systemic circulation. All systemic arteries have been arising from the main connector, aorta. Inspire of all this functions, the systemic circulation has been linked to supply most of the blood to the very needy bodily tissues, hence, it is known as the greater Circulation or peripheral Circulation (beings from the peripheral region). The main purpose of the systemic Circulation is to carry the elementary oxygen and nutrients to body tissues including the removal of carbon dioxide and other wastes from tissues.

2) Pulmonary Circulation: It is the flow of deoxygenated blood from the right ventricle of the heart and they return the oxygenated blood from the lungs to the left atrium is known as the pulmonary Circulation. The pulmonary trunk arising from right ventricle and then dividing into the right pulmonary artery and left pulmonary artery supplies the deoxygenated blood to the right lungs and left lungs respectively. Exchange of the gases are taken place here in these lungs. The two pulmonary veins from each lung transport the oxygenated blood to the left atrium.

Significance of the double Circulation include the checking of the irregular mixes of the oxygenated blood and the deoxygenated blood. Oxygenated blood carries more significant amount of oxygen, because of this, is more useful in providing the right amount of essential energy to the main tissues of the body. Deoxygenated blood will always carry a significantly higher amount of carbon dioxide for its immediate expulsion or elimination from the body, this is also a useful carrier to keep in check of the intoxicity rate develop in the blood as it becomes an early type of symptom to show in some diseases.

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

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 circulation and 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
