Question

Name two endocrine hormones that affect separate body systems. Name the tissue/organ that they target and the effects

Answer 1

Different Endocrine Hormones acts on Different Systems to produce certain effects.

For Example-

1.Anti Diuretic Hormone(ADH)/Vasopressin.

This is a Hormone that Affects Urinary System.

Vasopressin is Secreated by Posterior Pituitary Gland in Response to Increase in Plasma Osmolarity(Due to Excessive Loos of Urine).

ADH released from Posterior Pituitary Acts on its receptors cells in the collecting ducts,-----which leads to reabsorption of water into the circulation----Thus prevent Water Loss ---Reduces osmolarity.

2.Gastrin-

Gastrin is a Hormone That Affects Digestive System.

Gastrin is Secreated by G cells in the Antrum of Stomach,in response to food .(Mainly Protein containing food)

Gastrin acts on parietal cells of the stomach------Helps the release of Hcl from the Parietal cells of stomach----Increases Gastric Motility & Aids conversion of Pepsinogen into pepsin by Hcl.

It also binds to Cholecystokinin B receptors ------------Stimulate the release of Histamine From Enterochromaffin like cells-----Histamine acts on parietal cells ---Release of Hcl
