3) What is the function of pancreas?

4) How tongue is useful in ingestion?​

Answer 1

1. The main difference between ingestion and egestion is that ingestion is the intake of food into the body whereas egestion is the elimination of wastes out of the body. Ingestion occurs through the mouth in animals. In protozoa, ingestion occurs by endocytosis.

2.The villi and the microvilli increase intestinal absorptive surface area approximately 30-fold and 600-fold, respectively, providing exceptionally efficient absorption of nutrients in the lumen. There are also enzymes (enterocyte digestive enzyme) on the surface for digestion.

3. The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body's cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar.

4.The front part of the tongue is very flexible and can move around a lot, working with the teeth to create different types of words. This part also helps you eat by helping to move food around your mouth while you chew. Your tongue pushes the food to your back teeth so the teeth can grind it up.
