Answer:-

Digestion Process

The digestion process is a series of reactions of food with the digestive hormones and juices. This starts right from the oral cavity.

Why is digestion important?

It is an important process that breaks down the proteins, fats, carbohydrates, vitamins, minerals into simpler forms so that it can be absorbed easily into the body cells. During this process, proteins are converted into amino acids, carbohydrates are converted into simple sugars and fats are broken down into fatty acids and glycerol.

Many digestive enzymes and hormones act on food, at various stages during the process of digestion. The whole process occurs in a sequential manner.

The following table shows the digestive process in a simple format.

Digestive juices/enzymes added

Food that is broken down

Mouth Chewing Saliva Starch(Carbohydrate)

Oesophagus Peristalsis —- —-

Stomach Churning Stomach acid and Digestive Enzymes Proteins

Small Intestine Peristalsis Digestive Juices Carbohydrates, proteins, starch

Pancreas —– Pancreatic juice Carbohydrates, Fats, proteins

Liver —– Bile Fats

Large Intestine Peristalsis —- Bacteria act on the remaining food particles.

Mechanism of Digestion

The digestion process can be divided into different stages, such as digestion in the:

Oral cavity

Stomach

Small intestine

Large intestine

Digestion includes a complex combination of mechanical and chemical processes. Some of the activities in the process include ingestion and propulsion of food, mechanical or physical digestion, chemical digestion, absorption, and defecation.

Digestion in the Oral Cavity

When food is taken in through the mouth, chewing and mixing of the food occurs. There is also a chemical breakdown of carbohydrates, due to the action of saliva from the salivary glands. 30% of the starch is hydrolyzed by the action of amylase, which is a salivary enzyme. The other enzyme, lysozyme is an antibacterial agent that prevents infections.

Starch + Salivary amylase → Maltose

Mastication of food and swallowing of food are the important activities that take place here in the oral cavity. Food is broken down into smaller particles by the chewing action of teeth. As saliva is added, it mixes with the food particles, slowly moistening and lubricating the food. This small ball is called a bolus, which is then swallowed. The pharynx helps in the movement of the bolus into the oesophagus, from where it moves to the stomach through the peristaltic movements of the oesophagus.

Digestion in the Stomach

When food reaches the stomach, it stays and it would or might take 4-5 days to digest

Answer 2

Explanation:

a) liver helps in digestion of fats

b) gastric juices in activate swallowed microorganisms.

c) trypsin helps in digestion of proteins

d) lipase digest butter fat in our body

f) mucus is used as a lubricant for materials that that must pass over membrane.

e) bile juice breakdown the fats into fatty acids

g)HCL break down the proteins into amino acids
