Question:

Principal organ for the absorption of nutrients is

Options:

1. Buccal cavity
2. Stomach
3. Small intestine
4. Large intestine

Solution:

The principal organ for the absorption of nutrients is the small intestine. The small intestine is a long, narrow tube where the majority of the nutrients from food are absorbed. The inner lining of the small intestine has tiny finger-like projections called villi, which greatly increase the surface area for absorption. The villi are covered with even smaller projections called microvilli, which further increase the surface area for absorption. The small intestine absorbs nutrients such as carbohydrates, proteins, fats, vitamins, and minerals, which are then transported to the liver via the portal vein for processing and distribution throughout the body. The buccal cavity (mouth) and stomach also play a role in the digestion of food, but the majority of nutrient absorption occurs in the small intestine.
