• D. Excretion

Answer: (D)

Verified step by step guidance

1. Understand the concept of excretion: Excretion is the biological process by which an organism separates and eliminates waste products from its body. This is crucial for maintaining homeostasis and preventing damage to the body from toxic substances.
2. Differentiate between the terms: Filtration, Secretion, Absorption, and Excretion. Filtration involves the movement of water and solutes across a membrane due to pressure. Secretion is the release of substances from cells or glands. Absorption is the uptake of substances into cells or across tissues.
3. Identify the role of excretion in the body: Excretion involves organs such as the kidneys, liver, lungs, and skin, which help remove waste products like urea, carbon dioxide, and sweat.
4. Consider the physiological systems involved: The urinary system, including the kidneys, ureters, bladder, and urethra, plays a major role in excretion by filtering blood and forming urine to eliminate waste.
5. Recognize the importance of excretion in maintaining health: Efficient excretion is vital for removing metabolic waste, regulating fluid and electrolyte balance, and maintaining acid-base balance in the body.
