Answer: The stomach wall contains three tubular glands (gastric glands) that secrete gastric juice
What are the functions of gastric glands in the wall of stomach Class 10?
1) Pepsinogen: This is found in pepsin and helps in the digestion of protein . 2) Hydrochloric Acid: This is responsible for killing the germs present in the stomach which helps the enzyme by maintaining the acidic nature. 3) Mucous: This acts as a protective layer in the stomach against HCL.
What is the location and function of gastric glands Class 10?
GASTRIC GLANDS are present in the walls of the stomach and secrete GASTRIC JUICE .. The Gastric juice contains three substances-1)Hydrochloric acid,2)Enzyme Pepsin,3)Mucus....... Enzyme Pepsin helps in digestion of proteins and works on in the presence of an Acid i.e.HCL....
What are the functions of gastric juices Class 10?
The HCL present in the gastric juice dissolves bits of food and creates an acidic medium in our stomach . The enzyme pepsinogen is converted to pepsin in this acidic medium. Pepsinogen is a protein-digesting enzyme. It also kills bacteria and other microorganisms that enter along with the food in our stomach.
What are the functions of gastric glands present in the wall of stomach?
The gastric gland is an essential body component because it secretes gastric juice. The gastric juice contains hydrochloric acid, pepsin and mucus. Pepsin helps in digestion of proteins , hydrochloric acid helps in the functionality of pepsin and kills bacteria and mucus protects the inner lining of the stomach.
What are 4 cells of the stomach and their function?
Four major types of secretory epithelial cells cover the surface of the stomach and extend down into gastric pits and glands: Mucous cells : secrete an alkaline mucus that protects the epithelium against shear stress and acid. Parietal cells: secrete hydrochloric acid. Chief cells: secrete pepsin, a proteolytic enzyme.
What is the main function of the mucus found in the stomach?
Gastric mucus is a glycoprotein that serves two purposes: the lubrication of food masses in order to facilitate movement within the stomach and the formation of a protective layer over the lining epithelium of the stomach cavity .
What is the function of liver class 10?
The liver does many important things including: Makes bile , which helps carry away waste and break down fats in the small intestine during digestion. Makes certain proteins for blood plasma. Makes cholesterol and special proteins to help carry fats through the body.
What is human digestive system class 10?
Human digestive system- consists of the long alimentary canal that includes mouth, pharynx, oesophagus, stomach, small intestine, large intestine, rectum and anus . Nutrition in humans: ... Digestive juices – break down protein into simpler substances. The food from stomach eventually moves into the small intestine.
Which glands are present in the wall of stomach?
| Gastric glands | Latin glandulae gastricae | Anatomical terminology |
|---|
What is gastric juice function?
Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. Its main function is to inactivate swallowed microorganisms , thereby inhibiting infectious agents from reaching the intestine.
What is location and function of gastric gland?
The gastric glands are present in the wall of the stomach . Functions of gastric glands: 1. SECRETION OF HCl- The gastric gland releases hydrochloric acid which creates an acidic medium for the functioning of protein-digesting enzyme pepsin.
What are the content of gastric juice?
Gastric juice is highly acidic, with a pH of 0.9–1.5, and contains water (99%), hydrochloric acid (0.4%–0.5%), pepsin, lipase , glycoprotein and mucin, calcium, sodium and potassium salts, etc.
What is the role of HCL in stomach Class 7?
Functions of stomach:
HCl makes the medium acidic so that digestive enzymes can perform their functions. Mainly protein digestion occurs in stomach. HCl also kills the bacteria that may have enter along with the food we eat. The digestive juices break down proteins into smaller substances.
What is the main function of HCL present in gastric juice?
Hydrochloric acid is a strong acid secreted by the parietal cells, and it lowers your stomach’s pH to around 2. Hydrochloric acid converts pepsinogen into pepsin and breaks various nutrients apart from the food you eat . It also kills bacteria that comes along with your food.
What are the different components and functions of gastric juice Class 10?
Gastric juice contains three substances: hydrochloric acid, enzyme pepsin and mucus . Their functions are: Hydrochloric acid in the stomach is used to make the medium acidic to facilitate the action of the enzyme pepsin and to kill germs if any. Enzyme pepsin digests proteins to convert them into peptones.
