Question

Draw a labelled diagram of the transverse section of the pancreas and explain its role in the digestion of various food materials.

Answer 1

Digestion as we all know about this process is the breaking down of particles called bolus which pass through the esophagus and reaches the stomach. Before mixing into the blood and blood carries the nutrients for cell growth, cell repair and other things. Organisms obtain their nutrition from food or balance diet of different biomolecules like- Carbohydrates, proteins, fats, minerals and vitamins. As we know that nutrition is an essential mechanism in organisms.

Complete answer:
There are various steps in the nutrition process known as modes of nutrition, where we study about the steps or forms by which animals’ uptake food. Direct and indirect consumption can both provide nutrition. As important as the bodily movements, breathing mechanism, excretion process etc. it provides energy to the body in the form of food.
During digestion, the pancreas makes pancreatic juices called enzymes. These pancreatic enzymes help in breaking sugars, fats and starches. The pancreas also aids digestion by producing hormones. These are like chemical messengers that travel through the blood.
The pancreas has two primary functions: an exocrine role that aids digestion and an endocrine role that controls blood sugar levels.
As we discussed about how the pancreas helps in digestion and also act as an endocrine gland as also it secretes hormones which are equally vital to the body. All of the steps in nutrition and how they aid in bodybuilding and life maintenance. Animals also take food by autotrophic, heterotrophic, saprotrophic nutrition. They are the modes of nutrition.

Note:
As we know, the pancreas is an organ of the digestive system as well as an endocrine system. It is located in the abdomen behind the stomach. It is said that human beings can live without a pancreas if it has an infection and needs to be removed. But they are left without the cells of insulin cells are absent as pancreas secrete insulin hormone.
