When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚ then into single amino acids. Once the protein is digested into

hormones‚ enzymes‚ and waste products. Lipid absorption. Lymphatic vessels such as lacteals in the intestines absorb and transport large molecules‚ fats‚ and lipids in the digestive system mainly in the form of lipoprotein such as chylomicrons. The lymphatic system absorbs lipids and other substances from the digestive tract through lymphatic vessels called lacteals located in the lining of the small intestine. Lipids enter the lacteals and pass through the lymphatic vessels to the venous circulation.

With Crohn’s the immune system launches a direct attack on the digestive tract‚ leading to inflammation which can occur anywhere from the mouth to the rectum; although it is most commonly restricted to the small intestine. This constant state of inflammation causes physical damage to the lining of the area of the digestive tract affected‚ which leads to pain‚ ulceration‚ abcesses‚ along with frequent‚ watery bowel movements often accompanied by blood.
