Question

3. What is the significance of heart having four chambers?​

Answer 1

Answer:

Our heart has four chambers because two chambers (left auricle and right auricle) are responsible for sending the deoxygenated blood to the lungs for gaseous exchange and the other two chambers (right ventricle and left ventricle) are responsible for distributing the oxygenated blood in our whole body by Aorta.

Answer 2

The following are the key advantages of having a four-chambered heart:

• It enables the delivery of oxygenated blood to all regions of the body in a very effective manner.
• It guarantees that oxygenated and deoxygenated blood are completely separated within the heart.
• The atria (which receive blood) and ventricles (which pump blood) are clearly separated (pump the blood).
• The left half of the four-chambered heart is isolated from the right half, preventing the mixing of oxygenated and deoxygenated blood.
