Answer 1

Answer: (A), (C)

The correct options are
A Pumping oxygen rich blood to different areas of the body.
C Pumping carbon dioxide rich blood to the lungs.

• Heart pumps the oxygenated blood to all parts of the body, while the deoxygenated blood is brought back to the heart.
• This deoxygenated blood is now pumped from the heart to the lungs to get oxygenated again.
• The oxygen rich blood is then brought back to the heart from the lungs. Blood then enters the left atrium and then passes to the left ventricle.
• The blood from the left ventricle is pumped into another blood vessel, called aorta. The aorta pumps this oxygenated blood to all parts of the body.
