The small intestine is where the majority of food digestion occurs. At this point carbohydrates and proteins are already partially digested, while lipids have not yet begun. Chyme leaves the stomach and enters the duodenum (the 1st portion of the small intestine) via the pyloric sphincter. Here, maltase breaks down maltose into glucose monomers and peptidases break down peptides into amino acids. Bile is then released from the gall bladder and enters the small intestine via the bile duct to aid in the digestion of fats into glycerol and fatty acids. The chyme then enters the jejunum (the 2nd portion of the small intestine) where digestion continues and absorption begins(the jejunum is composed of many fold that increase its surface area and therefore improve absorption.) Glucose and amino acids are transported across the membrane by means of active transport (requires ATP) while glycerol and fatty acids require the help of carrier proteins (micelles (produced in the liver)) to enter the blood stream. Next, the chyme enters the ileum (the 3rd portion of the small intestine) which is mainly responsible for the absorption of select nutrients (ie. vitamin c). Once the chyme leaves the small intestine, most of the nutrients have been absorbed and only waste products and water remain; this is called liquid stool.

What else can I help you with?
Where in the body are protein absorbs?
Nutrients are absorbed in the small intestine. Protein absorption actually begins in the stomach, and continues throughout the digestive tract. The absorption rate depends largely on the source of the protein.
Where does absorption of protein take place?
Absorption of protein primarily takes place in the small intestine, specifically in the duodenum and jejunum. Proteins are broken down into amino acids by enzymes in the stomach and small intestine, and these amino acids are then absorbed through the intestinal wall into the bloodstream to be transported to different parts of the body for various functions.
Where in the body does the trypsin work?
Trypsin is a digestive enzyme produced in the pancreas that works in the small intestine. It breaks down proteins into smaller peptides and amino acids, assisting in the process of protein digestion and absorption in the gastrointestinal tract.
Is protein absorbed by the human large intestine?
Digestion of all food is completed in the small intestine, as is absorption. Large intestine is simply to pass undigested materials out of the body, and absorb what water the body requires.
What enables absorption of b12 across small intestine wall?
Intrinsic factor, a protein produced by the stomach, is required for the absorption of vitamin B12 in the small intestine. In the small intestine, vitamin B12 binds to intrinsic factor, forming a complex that can be absorbed through the intestinal wall.
A protein secreted by the stomach that is necessary for the absorption of vitamin B12?
The protein secreted by the stomach that is necessary for the absorption of vitamin B12 is called intrinsic factor. Intrinsic factor binds to vitamin B12 in the small intestine, allowing for its absorption into the bloodstream. Without intrinsic factor, vitamin B12 cannot be effectively absorbed and can lead to a deficiency.
What is the portion of the gastrointestinal tract that absorbs food?
The process of digestion is mainly in the stomach but lots of things are also digested in the small intestine e.g. maltose into glucose (enzyme used is maltase), protein into amino acids (protease is the enzyme) and lipids into glycerol and fatty acids (lipase is the enzyme) When these have been broken down they are absorbed through the lining of the small intestine where they are absorbed into the blood (absorbtion) and used as raw materials for growth and tissue repair (assimilation). So the answer is the small intestine Hope that helped =)
Which absorptive process in the small intestine requires a carrier and energy to transport nutrients into absorptive cells?
Active transport in the small intestine requires a carrier protein and energy (in the form of ATP) to move nutrients against their concentration gradient into absorptive cells. This process allows the absorption of nutrients like glucose and amino acids that are present at lower concentrations in the intestines compared to inside the absorptive cells.
What is the process that moves food from the small intestine to the blood?
The procces is called absorption. If you want to get technical, however, the name of the process depends on what the nutirent being absorbed is. For instance sodium is absorbed using a protein carrier, glucose uses that same carrier but for glucose it is called a symporter because it takes a "free" ride with sodium. Once the nutirents cross the intestinal wall they are sent to the mesenteric veins which take them to the liver and then to the circulation. If the absorbed nutrient is a big fat molecule then it takes a different path; it is picked up the the lacteals and sent directly to the circulation, thus bypassing the liver.
Is villi located in esophagus?
No, villi are not located in the esophagus. Villi are small, finger-like projections found in the small intestine that increase its surface area for nutrient absorption. The main function of the esophagus is to transport food from the mouth to the stomach.
Can you take whey protein with milk?
Yes you can, it gives you more protein and makes the protein absorption process slower and more constant. Personally i think it tastes better with water though.
Does protein digestion use peptidase made in the small intestine?
The protein is first broken down by PEPSIN (made in the gastric glands) in the stomach and/or TRYPSIN (made in the pancreas) in the duodenum. The protein is now broken down into DIPEPTIDES. The dipeptides are now broken down by peptidase (made by the intestinal glands) in the small intestine. The dipeptide is now an AMINO ACID. It is then absorbed by the capillaries in the villi of the small intestine. Hope that helped :)
