What is the largest organ in the digestive system? The largest part of the GI tract is the colon or large intestine. Water is absorbed here and the remaining waste matter is stored prior to defecation. Most of the digestion of food takes place in the small intestine which is the longest part of the GI tract. A major digestive organ is the stomach.

Essentially, it drains the structures supplied ultimately by the ...
Digestive Secretions and Absorption of Water. Absorption is a complex process, in which nutrients from digested food are harvested. Absorption can occur through five mechanisms: (1) active transport, (2) passive diffusion, (3) facilitated diffusion, (4) co …
Nutrient Absorption in the Digestive System. Carbohydrates, The small intestine is 5–6m in length, iron is absorbed in the duodenum, The later sections of the small intestines are covered with tiny, most nutrients are absorbed from the lumen of the alimentary canal into the bloodstream through the epithelial cells that make up the mucosa.
1995-1-5 · Iron Absorption Iron absorption is affected by the form in which iron is presented to the digestive tract, and inorganic iron ions change oxidation state during the absorption process. There are two major forms of dietary iron. Heme iron, found primarily in red meats, is the most easily absorbed form.
2021-10-12 · Iron—The ionic iron needed for the production of hemoglobin is absorbed into mucosal cells via active transport. Once inside mucosal cells, ionic iron binds to the protein ferritin, creating iron-ferritin complexes that store iron until needed. When the body has enough iron, most of the stored iron is lost when worn-out epithelial cells ...
2021-5-1 · Vitamins do not require digestion, but have varying chemical compositions, and as such are absorbed by the digestive system in different ways. Fat-soluble vitamins, namely vitamins A, D, E and K, follow the same absorption route as other lipid substances.
