Humans have two major organs that perform transport of materials. Organ 'A' is bean-shaped, dark red in colour and lie just above the waist. It helps in the removal of 'Q', a waste material from blood. The organ 'S' has the opening at the end of the urinary bladder through which the waste material is eliminated.
Organ 'B' lies in the chest cavity, slightly tilted towards the left side. It pumps continuously and pours liquid 'C' into arteries and through very fine tube-like structure 'D', distributes the liquid to various parts of the body. What are the name of these organs?
