Question

From the given picture of the digestive system, identify the part labelled as gastric gland.

(A) A
(B) B
(C) C
(D D

Answer 1

Digestion and absorption are the functions of the digestive system. Food is broken down into small molecules, which are then absorbed into the body during digestion. There are two main components of the digestive system:
a) The alimentary canal (intestinal tube) is a continuous tube with two openings: the mouth and the anus.
b) The teeth and tongue, salivary glands, liver, gallbladder, and pancreas are among the organs that make up the accessory organs.

Complete answer:
The alimentary canal starts from the mouth and ends at the anus. The food we eat through the mouth follows the path of oesophagus reaches the stomach, small intestine, large intestine, rectum and the undigested food is eliminated from the body through the anus. In all the parts, the food is digested by the digestive enzymes and absorbed.

To answer this question, We should check each part and should know the functionality of each part. We will realize that each part will be distinguished by its specific functions.
(A) A-This part is Oesophagus. The oesophagus's purpose is to move food from the mouth to the stomach and to prevent GER by preventing the retrograde flow of gastric contents into the oesophagus through the lower esophageal sphincter (LES).

(B) B- This portion secretes digestive juice that contains pepsin, a protein-splitting enzyme. Pepsinogen is an inactive type of pepsin that is secreted. This part is known as the stomach. It is also known as the gastric gland. (labelled B in the diagram).

(C) C-This part is Pancreas. It's about the same size as your palm. During digestion, the pancreas produces enzymes, which are pancreatic juices. Sugars, fats, and starches are broken down by these enzymes. Your pancreas also produces hormones, which aid digestion.

(D) D-This part is Descending colon (part of the large intestine). From just under the diaphragm at the top of the abdomen to the left pelvic area, the descending colon descends (goes downward) along the left side of the abdomen. The descending colon is where faeces are stored before being drained into the rectum.

Therefore the correct answer is option ‘B’.

Note: The three main cell types found in gastric glands are zymogenic, parietal, and mucous neck cells. The zymogenic (chief) cells are found at the gland's base and are thought to contain the enzymes pepsin and rennin. (Peptides are digested by pepsin, and milk is curdled by rennin.) The gastric gland is the stomach's main secretory unit. Since it secretes gastric juice, the gastric gland is an important body part. Hydrochloric acid, pepsin, and mucus are all contained in gastric juice. Pepsin aids protein digestion, hydrochloric acid aids pepsin's functionality and destroys bacteria, and mucus protects the stomach's inner lining.
