Answer 2

Answer:

• The deoxygenated blood from body is taken to the heart through veins.

• This blood first enters the right auricle from superior and inferior vena cava and then through the tricuspid valves, it goes to right ventricle.

• Now , from here the deoxygenated blood goes to lungs for purification through pulmonary arteries.
• After purification , the oxygenated blood is transferred to left auricle by the pulmonary veins .
• From left auricle , it goes to left ventricle via the bicuspid valve.
• Now, from here it released out through aorta and is distributed in the body via arteries.
• In this process the blood enters twice the heart, so this process is called double circulation .
