the walls of the stomach is alkaline and the food contain in the stomach is acidic.. it will not accept the nutrients to enter inside the stomach walls. the small intestine having villa in the walls and it ll absorb the nutrients in the food.
In an individual, processes that could occur include digestion of food in the stomach, absorption of nutrients in the small intestine, and filtration of waste products in the kidneys.
Secretion and absorption processes primarily occur in the digestive system. Secretion of digestive enzymes and acid takes place in the stomach, pancreas, and small intestine, while absorption of nutrients occurs mainly in the small intestine through its lining known as villi.
Most of the absorption of nutrients occurs in the small intestine. The inner surface of the small intestine is lined with finger-like projections called villi, which increase the surface area available for absorption. This is where the majority of nutrients from food are absorbed into the bloodstream.
Food undergoes chemical changes in the stomach, where it gets broken down by stomach acids and enzymes, and in the small intestine, where further digestion and absorption of nutrients occur.
Filtration of the blood and re-absorption of nutrients primarily occur in the kidneys, specifically in the structures called nephrons. The nephrons filter the blood to remove waste products and then reabsorb essential nutrients, electrolytes, and water back into the bloodstream.
Eighty percent of nutrient absorption occurs in the small intestine. The other 20% occurs in the stomach tissues.
The small intestine, or the duodenum, is where most absorption of nutrients occur.
In the small intestine
cuz the stomach is a loser
true
In an individual, processes that could occur include digestion of food in the stomach, absorption of nutrients in the small intestine, and filtration of waste products in the kidneys.
Almost all absorption of nutrients occurs in the small intestine. The small intestine is divided into three parts: the duodenum, jejunum, and ileum, where various enzymes and bile aid in the breakdown of food. The walls of the small intestine are lined with villi and microvilli, which increase the surface area for maximum nutrient absorption into the bloodstream. While some absorption occurs in the stomach and large intestine, the small intestine is the primary site for nutrient uptake.

Most chemical digestion occurs in the stomach and absorption occur in the intestines in humans and many other animals.
