Answer 1

Answer ⤵⤵⤵⤵

✔In double circulation, there are two pathways in which blood flows. They are:

⚫Pulmonary circulation

⚫Systemic circulation.

✔ Pulmonary circulation :-Pulmonary circulation moves blood between the heart and the lungs.It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide.

✔Systematic Circulation :- Systematic Circulation Carries oxygenated blood away from the heart to the body , and returns deoxygenated blood back to the heart.

DOUBLE CIRCULATION

In human beings blood passes twice through the heart for one complete circulation. First when it is deoxygenated and then after getting oxygenated. this referred to DOUBLE Circulation

the movement of blood through the vessels of the body that is induced by the pumping action of the heart and serves to distribute nutrients and oxygen to and remove waste products from all parts of the body .

the circulation of blood takes place in the body of by the the pumping action of the heart the right side of the heart receives deoxygenated blood in the right Atrium from the body through two major veins.

Deoxygenated blood from the anterior part of the body that the head,neck and arms is carried by the superior Vena cava . It is carried from the posterior part that includes leg and other lower parts by the inferior Vena cava .

Blood is pumped into the left ventricle which Pump It to the various body parts via an artery called Aorta. It is the largest artery in the body. It further divides into smaller artery to supply blood to all the body parts . When blood reaches the cells through capillaries it describes Oxygen and nutrients and collect carbon dioxide and other waste through the process of diffusion .
