The main function of the iliac crest is that it allows several muscles to attach to it. Some of these muscles include latissimus dorsi, iliacus muscle, and fascia lata.
The ilium is the largest of the three bones of the pelvis. It is an attachment site for the muscles of the abdominal wall.
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.
Ileum
mouth, esophagus, stomach, small intestine, large intestine, (duodenum, illeum jejunum), rectum
The large intestine, it absorbs all water, salt, minerals, and vitamins once it passes from the end of the small intestine (illeum) into the large intestine (colon) through the Ileocecal valve
Aggregate function
it is the large intestine
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.
illeum & cecum
The Cecum is the very first part of the Large Intestin (or Colon) into which the small intestine pushes its contents. It is in the lower right quadrant of the abdomen and the part the Appendix comes from. The Illeum is the final part of the small intestine where much of the absorption occurs. To move the food along its smooth muscle wall can conduct Peristalsis. This pushes the food into the cecum slightly above the base. When the colon conducts its own peristalsis the food is pushed up the ascending colon and past the entrance of illeum. The Ileocecal valve is between the illeum and the cecum to prevent the food that is pushed past entrance from going backwards into the illeum again instead of continuing around the tract.
Illeum
Ileum
mouth, esophagus, stomach, small intestine, large intestine, (duodenum, illeum jejunum), rectum
In the end of the small intestine. The illeum absorbs the nutrience and send into the blood system
The Duodenum and Illeum (both parts of the small intestine) through chemical digestion
The large intestine, it absorbs all water, salt, minerals, and vitamins once it passes from the end of the small intestine (illeum) into the large intestine (colon) through the Ileocecal valve
Carbohydrates begin digestion in the mouth with the help of the enzyme salivary amylase this process continues in the duodenum with the help of the enzyme amylase and it finishes off in the illeum still using amylase. Carbohydrates are broken down into polysaccharides which are chains of sugar and are then broken down into monosaccharides which are simple sugars. monosaccharides are the final break own product for carbohydrates. Proteins are digested in the stomach using the enzyme pepsin. continues to the duodenum and uses the enzyme trypsin and continues then to the illeum and uses the enzyme erepsin. proteins are broken down into polypeptides after this they are broken down into dipeptides and after this are then broken down into amino acids which is the final breakdown product. fats are broken down in the duodenum and the illeum . they are broken down in both using the enzyme lipase. they are broken down into fatty acids first and then into glycerol. glycerol is the final breakdown product for fats.
All the true organs of the gastrointestinal tract have a function. However there is one small part of the Large Intestine called the Cecum (where the Illeum of the Small Intestine connects into) from which a small projection called the Appendix is seen. The appendix is though to have once been a stomach for rumentation of plant matter (like cows do) but has since evolved into a useless tiny projection pron to inection and inflamation. It projects downwards from the cecyum in the bottom right of the abdomen.
