Chemical Digestion of Carbohydrates: Definition & Process

1. Chemical Digestion of Carbohydrates: Definition & Process

Carbohydrates are an important energy source, but must be broken down to be absorbed out of the digestive tract. In this lesson, you will learn how disaccharides and polysaccharides are broken down to monosaccharides through a process called hydrolysis.

Carbohydrate Digestion and Absorption: Process & End Products

2. Carbohydrate Digestion and Absorption: Process & End Products

Carbohydrates that you eat are broken down to monosaccharides by enzymes in your digestive tract. In this lesson, you will learn about these digestive enzymes and how monosaccharides are absorbed out of the digestive tract.

Protein Digestion and Absorption Process

3. Protein Digestion and Absorption Process

Protein is one of the primary nutrients your body uses to build cellular structures. In this lesson, you will learn how protein is broken down into amino acids within your digestive tract and how amino acids are absorbed out of the intestines and into the hepatic portal system.

Lipids Digestion and Absorption

4. Lipids Digestion and Absorption

Lipids, or fats, are digested and absorbed in the small intestine. In this lesson, you will learn how bile salts emulsify fat so pancreatic lipase can digest it. You will also learn how fats first enter lymphatic capillaries, called lacteals, before entering your blood circulation.

How Fiber is Digested by the Body

5. How Fiber is Digested by the Body

In this lesson, you will learn how and where fiber is digested in your body. You will also gain a clear understanding of the different types of fiber and their potential health benefits.

Absorption of Micronutrients and Water into the Bloodstream

6. Absorption of Micronutrients and Water into the Bloodstream

In this lesson, you will gain a deeper understanding of how and where absorption of micronutrients and water take place in your body. You will also learn how and where it enters your bloodstream.

Absorption of Nutrients to the Lymphatic System

7. Absorption of Nutrients to the Lymphatic System

In the lesson, we will explore the lymphatic system and how it functions. You will learn about the parts of your body that make up your lymphatic system and what nutrients are absorbed there.

How are Nutrients Transported Around the Body?

8. How are Nutrients Transported Around the Body?

There are specific steps involved in nutrient transportation to ensure that your body gets what it needs to function properly. This lesson explores how nutrients are transported throughout your body.

Circulatory System II: The Human Vascular System

9. Circulatory System II: The Human Vascular System

In this lesson, learn all about the operation of the human vascular system. What are the different types of blood vessels? How does blood flow through the human body? How does the system adapt to your body changing?

Lymphatic Vessels: Definition & Function

10. Lymphatic Vessels: Definition & Function

In this lesson, you will learn what lymphatic vessels are and why they are important for fluid management, immune function, and fat absorption. You'll then take a short quiz to test your knowledge.
