What organ removes waste created by digestion?

What organ removes waste created by digestion?

• A. Liver
• B. Heart
• C. Kidneys
• D. Lungs

Answer: (A)

The correct answer is the liver. The liver plays a crucial role in the digestive process and is responsible for metabolizing nutrients from the food we consume. It removes waste products from the blood, including those generated from digestion and metabolism. The liver processes these products to prepare them for removal from the body, either as bile (which aids in digestion and fat absorption) or through conversion into less harmful substances that can be excreted by other organs. While the kidneys also remove waste from the body, their primary function is to filter blood and excrete waste products as urine, particularly those related to the balance of excess fluids, electrolytes, and metabolic waste. The heart is responsible for circulating blood throughout the body, but it does not participate in waste removal, and the lungs facilitate the exchange of gases, removing carbon dioxide from the bloodstream, but they are not involved in processing digestive waste. Understanding these functions helps clarify why the liver is central to waste removal related to digestion.
