Question

In bird and mammals the left and right side of the heart are separated. Give reasons.

Answer 1

Answer:

The separation of the right and left side of heart is useful to prevent oxygenated blood and deoxygeneted blood from mixing. Such separation allows a highly efficient supply of oxygen to the body.

Answer 2

Answer:

The separation keeps oxygenated and deoxygenated blood from mixing allowing a highly efficient supply of oxygen to the body.

Explanation:

• The septum separates the left and right sides of the heart.
• Valves prevent the backflow of blood and separate the atria from the ventricle and the ventricle from the pulmonary artery or aorta.
• The right side of your heart collects blood on its return from the rest of the body.
• The blood entering the right side of your heart is low in oxygen. The heart pumps the blood from the right side to the lungs.  
• The blood returns directly to the left side of the heart from the lungs, then pumps it out again to all parts of your body through an artery called the aorta.
