Digestion functions are taken care of by the gastric glands present in the wall of the stomach. These release hydrochloric acid, a protein digesting enzyme called pepsin, and mucus. What is the function of mucus? Correct Answer It protects the inner lining of the stomach from the action of the acid under normal conditions

The correct answer is it protects the inner lining of the stomach from the action of the acid under normal conditions.

Explanation:

  • The glands of the stomach are called gastric glands.
  • These are found in the stomach mucosa.
  • Gastric glands secreted hydrochloric acid, a protein-digesting enzyme called pepsin and mucus.
  • Functions of mucus:
    • Mucus protects the inner lining of the stomach from the action of the acid under normal conditions.
    • It acts as a barrier against bile salts, stomach acid, macromolecules, and pancreatic enzymes.
    • By secreting sticky, neutralizing mucus that clings to the stomach walls, stomach protects itself from being digested by its own enzymes or burned by the corrosive hydrochloric acid.
    • If the stomach wall is damaged in any manner, it can cause painful and uncomfortable stomach ulcers.
    • If the mucus is not secreted, HCI will promote erosion of the stomach lining, resulting in ulcer formation.

Additional Information

  • Functions of hydrochloric acid and pepsin.
    • Hydrochloric acid (HCI): Hydrochloric acid helps in the breakdown, digestion, and absorption of nutrients such as protein. It also kills germs and viruses in the stomach, keeping your body safe from infection.
    • Pepsin: It helps to convert big polypeptides into smaller peptide fragments.

The human eye is a complex part of the body that is used for seeing. Eyes enable people to perform daily tasks and to learn about the world that surrounds them. Sight, or vision, is a rapidly occurring process that involves continuous interaction between the eye, the nervous system, and the brain. When someone looks at an object, what he really sees is the light reflected from the object. This reflected light passes through the lens and falls on the retina of the eye. Here the light induces nerve impulses that travel through the optic nerve to the brain and then over other nerves to muscles and glands.
The eye is similar to a television camera. Both the eye and the television camera convert light energy to electrical energy. The eye converts light to nerve impulses that are interpreted by the brain as the sense perception called sight. A television camera converts light to electronic signals that are broadcast and transformed into light images in a television receiver. It is wonderful that human eyes blink an average of once every six seconds. This washes the eye with the salty secretion from the tear or lachrymal glands. Each tear gland is about the size and shape of an almond. These glands are situated behind the upper eyelid at the outer corner of the eye. After passing over the eye, the liquid from the gland is drained into the nose through the tear duct at the inner corner of the eye. Lachrymal glands or tear glands are situated
