Secretion function in the small intestine.. inside the digestive tract and into the blood. Mucus from the cavernous cells. Immunoglobulin immunoglobulin. Serotonin proteins. Water and electrolytes. Hormonal hormones



Function of secretion:
External secretion: "into the intestinal tract":
- mucus from the cells.
- Immunohistochemistry of defensive secretion: especially IgA secretory.
Serotonin proteins: which may be excreted in some pathological conditions such as the gastrointestinal disease of the protein.
- Water and electrolytes: Not produced by the intestine in the normal state, but in some cases, such as cholera, under the influence of cholera toxin, which makes the intestinal cells "water" into the water, water diarrhea occurs, and the secretion of water and electrolytes due to the use of some drugs or when they gather Some sugars that are not absorbable significantly at the expense of their concentration in the blood and the intestine in the water (Tanash).
Internal secretion: "to the blood":
It contains several substances (digestive hormones) that are excreted from the cells of the endocrine directly into the blood: Gastrine, CCK, Somatostatine Secertine, VIP, GIP, Motoline.
