Hormones

Two key hormones stimulate the production of pancreatic juice and bicarbonate:

Cholecystokinin (CCK): This hormone is released by the small intestine in response to the presence of fats and proteins. It stimulates the pancreas to secrete enzyme-rich pancreatic juice that aids in digestion.

Secretin: This hormone is released in response to acidic chyme entering the small intestine. It stimulates the pancreas to produce bicarbonate-rich pancreatic juice to neutralize the acid. Together, these hormones ensure the proper breakdown of food in the digestive system.

The correct Option is : 2

Step 1: Function of theca interna.
The theca interna is a layer of cells in the ovarian follicle that plays a critical role in hormone production. It synthesizes androgens, which are precursors to estrogen.

Step 2: Hormone production.
The granulosa cells, under the influence of FSH, convert the androgens produced by the theca interna into estrogen through aromatization.

Step 3: Explanation of other options.
Option (A): Incorrect. Progesterone is primarily produced by the corpus luteum, not theca internal.

Option (C): Incorrect. LH (luteinizing hormone) stimulates theca interna but is not secreted by it.

Option (D): Incorrect. FSH (follicle-stimulating hormone) regulates granulosa cells, not theca interna.
