(a) The human circulatory system consists of the heart, blood vessels and capillaries, and circulating fluid blood.

(c) Excretion is the process of removal of harmful metabolic wastes from the body. The organ system that performs the function of excretion is known as the excretory system.
(d) Some of the waste products formed in plants include gum, resins, oxalate crystals, sap and catechu.
