Diffusion is needed in the small intestine so that nutrients from digested food can be diffusedinto the blood vessels of the intestine wall. The lining of this wall is called the mucosa and is covere in tiny wrinkles that form indents in the surface. Not only does this increase surafce area but there are tiny hairs called villi as well that add even more surface area. The villi are also covere in microvilli. Rhis means more surface for nutrient absorption. Furthurmore these villi are only one cell thick meaning substances cam easily be exchanged to and from the blood vessels.
Glucose is absorbed into the bloodstream through a process called facilitated diffusion in the small intestine. Specialized proteins called glucose transporters help move glucose molecules from the intestine into the bloodstream, where it can be used for energy by the body's cells.
The small intestine contains villi. Villi are small finger-like projections on the inner lining of the small intestine that help increase the surface area for absorption of nutrients.
After the small intestine, the digested food enters the large intestine, also known as the colon. The main function of the large intestine is to absorb water and salts from the material that has not been digested as food, and to help the body eliminate solid waste.
The pancreas secretes digestive enzymes and bicarbonate into the small intestine to aid in digestion, while the liver produces bile which is released into the small intestine to help with the digestion of fats.
The small intestine requires a rich blood supply to deliver nutrients absorbed from food to the rest of the body. The blood vessels in the small intestine also help remove waste and transport it to the liver for processing. This intricate network of blood vessels supports the high metabolic activity of the small intestine.
Large surface area Thin- Short distance for diffusion
the villi in the small intestines.
The small intestine is where your food goes after the stomach. The small intestine digests your food, then sends it to the large intestine.
yes it is! but the large intestine is shorter then the small intestine...Did that help? Hope I did! :)
the three glands that help to complete the digestion are large, intestine small intestine and kidney
The small intestine has many villi, small projections into the lumen of the small intestine. These villi increase the surface area of the small intestine, and increase the funcitonal area for the absorbtion of nutrients.
Glucose is absorbed into the bloodstream through a process called facilitated diffusion in the small intestine. Specialized proteins called glucose transporters help move glucose molecules from the intestine into the bloodstream, where it can be used for energy by the body's cells.
The duodenum (the first part of the small intestine).
The first part of the small intestine, or duodenum, is where the small intestine receives bile to help digest fats.
it doesn't
They are the large and small intestine
The small intestine contains villi. Villi are small finger-like projections on the inner lining of the small intestine that help increase the surface area for absorption of nutrients.
