Answer 2

Answer:

• The chamber of heart which receives oxygen rich blood is called the left auricle.

• The left auricle receives the oxygen rich blood from the lungs through pulmonary vein.

• The oxygen rich blood from the left auricle goes into the left ventricle.

• The blood is then pumped to the whole body.

• The blood reaches each and every part of the body through Aorta.

• The transportation system of human being is a double system.

• It is said to be a double system because once the blood comes of the heart through vena-cava and then for the exchange of gases it has to go to the lungs and come back to heart to be pumped in the whole body. This cycle repeats.
