During catabolism, complex compounds within the cells are broken down into smaller ones. This process is essential for releasing energy and breaking down nutrients for various cellular functions. Purification of the body by eliminating waste matter is more closely associated with the process of excretion and not specifically catabolism. The steady circulation of blood being controlled is linked to the mechanisms of homeostasis and cardiovascular regulation. Building larger molecules from smaller ones is characteristic of anabolic processes, not catabolism. Therefore, the correct answer is A because it describes the breakdown of complex compounds into smaller ones during catabolism.
