Question

Which one of the following pairs of the kind of cells and their secretion is correctly matched?
a) Oxyntic cells- A secretion with Ph between 2 and 3
b) Alpha cells of islets of Langerhans- secretion that decreases blood sugar level
c)Kupffer cells- a digestive enzyme that hydrolyses nucleic acids
d)Sebaceous glands- a secretion that evaporates for cooling

Answer 1

Hint: The secretion caused by a cell or a gland is used for the different purposes. Secretion involves the movement of the substances from one point to the another and is released chemically from either cell or gland due to the generation of some signals.

Complete answer:
The oxyntic cells are also known as parietal cells. they are present in the inner lining of the stomach. They are the epithelial cells present in the stomach. They help in the secretion of the hydrochloric acid. These cells usually are present in the fundus and cardiac region of the stomach. When the food enters the stomach, a signal is generated which makes them release the hydrochloric acid and the intrinsic factor.

Additional Information: Alpha cells of islets of Langerhans secrete the glucagon hormone. They help in increasing the glucose level in the blood. Hence, increasing the blood sugar level to an optimum level. The Kupffer cells are present in the liver. They help to destroy the foreign particles that enter our body. They also remove the worn-out cells present in the blood. Sebaceous glands are present on the surface of the skin. They help in the secretion of the oily substances called sebum which helps in the lubrication of the skin.
So, the answer is ‘oxyntic cells-a secretion with ph. between 2 and 3’.

Note: The oxyntic cells release hydrochloric acid and intrinsic factors. They help in the absorption of the vitamin $B_(12)$ from the stomach as it is absorbed from the intrinsic factor released by the cells. These cells are activated by the neural and the endocrine stimulations.
