Excretion is defined as?

• A. The body's way of removing the waste products
• B. The passage into the bloodstream
• C. The transportation to tissues
• D. Biotransformation

Answer: (A)

Excretion is the body's process of removing waste products produced by metabolism from the body. This includes wastes like urea and creatinine in urine, undigested material in feces, carbon dioxide from the lungs, and sweat from the skin. It’s about getting rid of substances the body no longer needs or that could be harmful if they accumulated. This differs from absorption (substances entering the bloodstream), distribution (movement to tissues), and biotransformation (chemical changes to substances, or metabolism). So the description that matches excretion is the body's method of eliminating waste products.
