Once food passes out of the stomach, enzymes get to work on the nutrients in the small intestine, breaking them into smaller products. It is also in the small intestine where substances are absorbed into the bloodstream. This absorption takes place in tiny, finger-like structures called villi. These line the walls of the intestine, and are ideal for the diffusion and active transport of molecules.
The Small intestine plays the greates role
small intestine
jejunum
The digestive system is responsible for themechanical and chemical digestion of food products, for the absorption of nutrients, and the excretion of waste products. The proper functioning of the digestive system is necessary for proper nutrient absorption. Nutrients are critical to ensure overall good general health.BASICALLY I JUST USED MY COMMON SCENSE hope i helped sorry if i didnt im not good in science
its absorption
heart
is the stomach importantwith regard to absorption of digesive end products
In the small intestine
absorption
The absorption of amino acids, simple sugars (such as glucose), vitamins and minerals involves active transport processes. in contrast, the products of fat (fatty acids) digestion are lipid-soluble molecules and are able to diffuse easily through the membranes of the intestinal cells.
The rectum is the final part of the digestive tract, and is where faeces, the waste products of digestion, are stored until they are expelled from the body. All the waste will then leave by the anus.
The renal system eliminates some of the waste products produced by digestion; in particular proteins.
Proteins-----(protease enzymes)---->amino acids.
The rectum is the final part of the digestive tract, and is where faeces, the waste products of digestion, are stored until they are expelled from the body. All the waste will then leave by the anus.
The function of the ileum is mainly to absorb vitamin B12 and bile salts and whatever products of digestion were not absorbed by the jejunum.
