Question

The food mixes thoroughly with the acidic gastric juice of the stomach by the churning movement of its muscular wall. What we called the food then?
A. Bolus
B. Chyme
C. Succus entericus
D. Chylomicron

Answer 1

Hint: The food mixes thoroughly with the acidic gastric juice of the stomach by the churning movement by this a thick, highly acidic, semi-liquid material made by the digestive juices of your stomach, which interact with the food that we eat. It is a product of two forms of digestion - mechanical and chemical digestion and without it we do not get the required nutrients.

Complete answer:
Bolus-Bolus is a ball-shaped mixture of food and saliva that forms in the mouth during chewing (most suitable for mammals that feed on plants). It is the same colour as the food you eat, and saliva provides an alkaline pH.
Succus entericus-Intestinal juice, also known as serous fluid, is a fluid that is secreted in small quantities from the small intestine. Secretion of Succus entericus is alkaline. It is produced by duodenal wall glands and It consists of water, bicarbonate ions and mucous proteins. This serous fluid is formed by the secretion of the brush border cells of the mucous membrane with the secretion of goblet cells. Fights strong acids and proteolytic enzymes that enter the small intestine from the stomach and protect the duodenum from damage.
Chyme- Chyme is the product of the mechanical and chemical breakdown of the bolus and consists of partially digested food, water, hydrochloric acid and various digestive enzymes. The Chyme slowly passes through the pyloric sphincter and enters the duodenum, where it begins to extract nutrients.
Chylomicrons, formed in the intestinal mucosa during the digestion of digestive products, are very large lipoprotein complexes that circulate through the lymphatic vessels. These triglycerides in chylomicrons are broken down into glycerol and free fatty acids, reaching fat cells and re-esterified by the catalytic action of lipoprotein lipase.
So, the correct answer is “Option B”.

Note:
Chyme has a low pH, which fights bile production and helps digest food.. Some cells from the mouth and oesophagus are separated by the mechanical actions of chewing and swallowing including in the Chyme.
There are two main functions of Chyme: the first is to increase the surface area of ​​food so that digestive enzymes can do their job, and the second is to stimulate the various digestive glands to break out.
