Chapter 9: Nutrition and Digestive System of Humans

What you need to learn in this chapter

In this chapter, we will learn about the nutrition and digestive system of humans. We will start by identifying the structures of the human digestive system. Next, we will explore the different types of digestion, including physical and chemical digestion. We will also analyze the process and products of carbohydrate digestion in the mouth. Moving on, we will study and focus on the structure of a villus in the ileum. We will discuss the adaptations of the ileum and villus in the absorption of digested food. Lastly, we will delve into assimilation. We will describe the roles of the circulatory system in the assimilation of digested food. Additionally, we will discuss the functions of the liver in assimilation, including the metabolism of digested food, storage of nutrients, and detoxification. By the end of this chapter, we will have a comprehensive understanding of the nutrition and digestive system of humans and how our bodies process and utilize food for energy and growth.
