Question
State the importance of excretion in living organisms.
Answer
1. Elimination of metabolic wastes to prevent accumulation to toxic levels. Excretion is the primary mechanism through which waste products, such as carbon dioxide, urea, and ammonia, are eliminated from the body. These waste products result from metabolic processes and, if allowed to accumulate, can be toxic and disrupt cellular functions.
2. Excretion helps maintain internal balance by regulating the levels of water, ions, and other substances in the body. Proper excretion of excess water and electrolytes is essential for maintaining proper fluid and electrolyte balance, which is crucial for normal cellular function.
