What is the process of eliminating waste from the body called?

• A. Absorption
• B. Digestion
• C. Defecation
• D. Excretion

Answer: (D)

The process of eliminating waste from the body is referred to as excretion. This physiological function involves the removal of metabolic waste products and excess substances from the bloodstream, primarily through organs such as the kidneys, lungs, and skin. Excretion plays a crucial role in maintaining the body's internal balance, ensuring that harmful substances do not accumulate to toxic levels. It encompasses the elimination of substances like urea, carbon dioxide, and other metabolic waste that result from cellular processes. While defecation is a specific type of waste elimination that refers to the expulsion of solid waste from the digestive tract, it is part of the broader excretory process. Absorption and digestion, on the other hand, involve the intake and breakdown of nutrients rather than the removal of waste. Thus, excretion is the most appropriate term for the overall process of disposing of waste products from the body.
