Anatomy and physiology of digestion
In this subject, you will learn about the complex physiological processes that occur after food intake and the anatomical structure of our gastrointestinal tract.
The digestive tract is a complex mechanism that starts after food intake. Digestion begins in the mouth, where food is digested through chewing and mixing with saliva. The next step is the utilization of food in the stomach, where it is further broken down and mixed with gastric juice. Then, the food enters the small intestine, where most of the digestion and absorption take place. Digestion is finally completed in the large intestine, where the food is processed into stool.
The different areas of the digestive tract are introduced and explained in terms of how it functions. Before that, the structure and function of the biological membrane are explained. The biological membrane is a protective barrier that exists around each cell and prevents foreign substances from entering the cell. The membrane consists of a lipid bilayer surrounded by proteins. These proteins are responsible for regulating the influx of nutrients into the cell. Digestion is influenced by many factors, including the type of food, the amount of food, the time of day, and the overall health condition of the body.
This is a crucial subject for the nutritionist training program.
