Question

Explain the circulation of blood

Answer 1

Deoxygenated blood is collected from all the parts of body and is carried to lungs which purify blood and this oxygenated blood is taken to heart by arteries which then pumps this blood to all the parts of body.arteries carry oxygenated blood and veins carry deoxygenated blood.

Answer 2

Answer :

Humans have double circulation.

This means that blood passes through the heart twice as it goes once around the body it works like this :

The right side of the heart pumps blood to the lungs to collect the oxygen and get rid of carbon dioxide.

The left side of the heart pumps blood to the rest of the body to supply cells with oxygen and pick up carbon dioxide and other waste.

When blood gets to the body cells, a liquid called tissue fluid passes across the wall capillaries. Substances such as oxygen, carbon dioxide move in both directions through the walls by diffusion.

Process :

$\boxed{\sf Right\;Atrium}} \longrightarrow \boxed{\sf Right\;Ventricle}} \longrightarrow \boxed{\sf Pulmonary\; Artery}} \longrightarrow \boxed{\sf Lungs}} \longrightarrow \boxed{\sf Left\;Atrium}} \longrightarrow \boxed{\sf Left\;Ventricle}} \longrightarrow \boxed{\sf Aorta}} \longrightarrow \boxed{\sf Rest\;of\;the\;body.}}$
