1. Ingestion: The GIT (Gastrointestinal Tract) starts with the mouth, where food is ingested and the process of digestion begins.

2. Secretion: The GIT secretes about 7 liters of fluids per day, including mucus, acid, and enzymes, to help break down the food.

3. Mixing and Movement: The muscles in the GIT mix the food and fluids, and propel them towards the rectum for elimination. This process is known as peristalsis.

4. Digestion: This is the main function of the GIT. It involves breaking down the food into nutrients. There are two types of digestion - mechanical, where the food is physically broken down into smaller pieces, and chemical, where enzymes break down the food into its nutrient pieces.

5. Absorption: The GIT absorbs the nutrients from the food into the bloodstream. The absorbed substances include water, vitamins, minerals, carbohydrates, proteins, and fats.

6. Excretion: The GIT excretes waste products from the body in the form of feces. This includes undigested parts of the food, bacteria, and worn-out cells from the GIT lining.
