Question

Give any two classes in which we find double circulation
​

Answer 1

Double circulation is the most efficient way of circulation. Here, in humans, the four-chambered heart, arteries, veins, and capillaries all have a vital role to play. Blood gets pumped out of the heart. This blood goes to different organs and then blood again comes back to the heart.

Answer 2

Two classes of double circulation :

• Circulation is of two type: They are Pulmonary Circulation and Systemic Circulation.
• Pulmonary circulation passes blood linking the heart and the lungs.
• It carries deoxygenated blood to the lungs to take up oxygen and discharge carbon dioxide.
• The oxygenated blood then passes back to the heart. This means we have two types loops in the body in that the blood flows.
• One is oxygenated, which merans the rich amount of oxygen, and the other one is deoxygenated, which refers that it has "small to no oxygen", but a more of carbon dioxide.
