Question

Bile juice is secreted from
(a)Salivary gland
(b)Intestinal gland
(c)Stomach
(d)Liver

Answer 1

Hint: Bile juice contains bile acid, which is essential for digestion and absorption of nutrients from the food. A bile is secreted from an organ which is an endocrine and exocrine gland.

Complete answer:
Bile juice contains bile acids, which are essential for digestion and absorption of-soluble vitamins, and fats in the small intestine. Some of the waste products including bilirubin, are eliminated from the secretions of the body and also eliminated through faeces. Bile is stored in the gallbladder and it's secreted by the Liver. It's main function is to digest the food.
It plays several important functions, among them is to assist with fat digestion and absorption in the gut. It is a medium for our body to excrete waste products(metabolic wastes) from the blood.

Additional Information
Salivary glands of adults contain enzymes that hydrolyze (breakdown) starch, sucrose, and trehalose. Amylase and sucrase are the enzymes that are secreted by the Salivary gland, while trehalase remains in the gland.
Enzymes are secreted by the intestinal gland.
Enzymes that are secreted are peptidase, sucrase, maltase, lactase, and intestinal lipase. In contrast to the gastric glands of the stomach, where chief cells are the prominent glands to secrete pepsinogen.
The stomach secretes pepsin enzyme which is mainly responsible for the digestion of proteins. These are found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin, activating for the functions to be performed.

So, the correct answer is ‘Liver’.

Note: Hydrochloric acid is secreted by the lining of the stomach. It's responsible for the checking of the invasion of microbes (for possible infections in the future).
