What is the largest internal organ of the human body? A. heart C. liver B. gall bladder D. stomach
The Correct Answer and Explanation is:
The largest internal organ of the human body is B. liver.
Explanation:
The liver is the largest internal organ and plays a crucial role in maintaining many vital functions in the body. It is located in the upper right portion of the abdomen, below the diaphragm. The liver is involved in a variety of essential metabolic processes, including:
- Detoxification: The liver filters out toxins from the blood, such as alcohol and drugs, and breaks them down into less harmful substances that can be excreted through the urine or bile.
- Metabolism: The liver helps regulate blood sugar levels by storing glucose as glycogen and converting it back into glucose when needed. It also plays a key role in lipid (fat) metabolism and protein synthesis.
- Storage of Nutrients: The liver stores essential nutrients such as vitamins (A, D, B12) and minerals (iron and copper). It also stores glycogen, which can be converted into glucose to provide energy when necessary.
- Bile Production: The liver produces bile, a substance that helps in the digestion and absorption of fats in the small intestine.
- Blood Clotting: The liver produces proteins that are vital for blood clotting, which helps prevent excessive bleeding when injuries occur.
The heart (option A) is crucial but is not the largest internal organ. It is a muscular organ that pumps blood throughout the circulatory system. The gall bladder (option B) is a small organ that stores bile produced by the liver. The stomach (option D) is involved in digestion but is smaller in size compared to the liver.
In summary, the liver stands out as the largest internal organ due to its size and the extensive range of vital functions it performs in maintaining homeostasis.
