Question

diagram of double circulatory system
class 10 ​

Answer 1

Explanation:

In double circulation, there are two pathways in which blood flows. They are: 1) Pulmonary pathway 2) Systemic pathway. The pulmonary circulation or pathway carries the deoxygenated blood from the right side of the heart to the lungs.

Answer 2

Answer:

Diagram in attachment. (I drew it in MS Paint. You may draw the same by hands.)

Explanation:

First of all, oxygenated blood enters the heart from the lungs via the pulmonary vein. The blood is poured into the left auricle, it then goes to the left ventricle and then is sent to all the body parts via aorta.

Then, all body cells use the oxygenated blood for respiration and then the de-oxygenated blood, containing carbon-dioxide is sent back to the heart via the superior and inferior vena cava.

Blood enters the right auricle, moves into the right ventricle and then is sent to the lungs via the pulmonary artery. In the lungs, carbon-dioxide moves outside the body, we inhale oxygen and then the oxygenated blood is sent to the left auricle via the pulmonary vein and the cycle continues.
