Dear Student,

a) The blood vessels which bring blood to the heart are Superior and Inferior vena cava which brings blood to right atrium and pulmonary veins which bring blood to left atrium,
The aorta carries away blood from left ventricle to the body parts.
The pulmonary trunk carries blood from right ventricles to the lungs.

b) Carbon dioxide and Oxygen are the two substances that are carried by blood.
