masya89 [10]

This is a specific response because in order to fight antigens, white blood cells, the most important cells of the immune system, must produce large, Y-shaped proteins known as antibodies to fight these invaders.

Which digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine?.
blsea [12.9K]

Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.

  • A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone.
  • It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide.
  • The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.
  • The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid.
  • Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.
