Anatomy and Physiology of the Mouth

1. Anatomy and Physiology of the Mouth

The digestive system is a long tube that breaks food down both mechanically and chemically. In this lesson, you will learn about the mouth and how it begins the digestive process - with the help of the teeth and the enzyme called salivary amylase.

Anatomy of the Throat and Esophagus

2. Anatomy of the Throat and Esophagus

After food has been partially broken down in the mouth, it moves through the pharynx, or throat, and the esophagus. In this lesson, you will learn how food is swallowed and how it is propelled by peristalsis through the esophagus.

Anatomy and Physiology of the Stomach and Autonomic Nervous System Controls

3. Anatomy and Physiology of the Stomach and Autonomic Nervous System Controls

In this lesson, you will learn how the unique anatomy of the stomach - including rugae, gastric pits and gastric glands - makes it a perfect organ for digestion. You will also learn how the autonomic nervous system controls digestion.

Physiology of the Stomach and Gastric Juices

4. Physiology of the Stomach and Gastric Juices

When food enters your stomach, it is mechanically broken down by a process called churning. In this lesson you will learn about this process and the chemical break down of proteins within the stomach by the enzyme pepsin.

What is the Small Intestine? - Anatomy and Functions

5. What is the Small Intestine? - Anatomy and Functions

In this lesson, you will learn about the three divisions of the small intestine - the duodenum, jejunum, and ileum. You will also gain an understanding of the basic functions of each of these sections, including their role in removing bacteria.

What Is the Pancreas? - Function, Enzymes & Role in Digestion

6. What Is the Pancreas? - Function, Enzymes & Role in Digestion

Your pancreas plays an important role in the digestion of food. In this lesson, you will learn about the enzymes found in pancreatic juice that allow your body to break down carbohydrates, proteins and fats.

The Gallbladder & Liver: Function & Role in Digestion

7. The Gallbladder & Liver: Function & Role in Digestion

Bile is produced by the liver and stored in the gallbladder. In this lesson, you will learn about bile and its role in the breakdown of dietary fats. You will also learn how the hormones secretin and cholecystokinin help regulate these organs.

Movement Through the Small Intestine: Peristalsis, Segmentation & Pendular Movement

8. Movement Through the Small Intestine: Peristalsis, Segmentation & Pendular Movement

The small intestine is an important organ for digestion and absorption of nutrients. In this lesson, you will learn about the enterogastric reflex. You will also learn how intestinal movements, such as peristalsis, segmentation, and pendular movement, improve digestion and absorption.

Small Intestine: Nutrient Absorption and Role In Digestion

9. Small Intestine: Nutrient Absorption and Role In Digestion

The majority of digestion and absorption of nutrients takes place in the small intestine. In this lesson, you will learn about unique modifications within the walls of the small intestine, such as microvilli, villi, and circular folds. These structures increase absorption of nutrients.

Anatomy and Physiology of the Large Intestine

10. Anatomy and Physiology of the Large Intestine

The large intestine is the made up of the cecum, colon, rectum and anal canal. In this lesson, you will learn about the anatomical features and basic functions of these large intestine segments.

Rectum, Functions of the Large Intestine & Water Absorption

11. Rectum, Functions of the Large Intestine & Water Absorption

The large intestine is the final processing area for digested food. In this lesson, you will learn how the large intestine removes water from undigested food and prepares for the elimination of feces through the anus.

Chemical Digestion of Carbohydrates: Definition & Process

12. 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

13. 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

14. 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

15. 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.

Transverse Colon: Definition & Function

16. Transverse Colon: Definition & Function

The transverse colon is a part of the large intestines. In this lesson, learn the structural details, as well as the functionality of this important part of the digestive system.

Sclerosing Mesenteritis: Causes & Treatment

17. Sclerosing Mesenteritis: Causes & Treatment

Sclerosing mesenteritis is a rare but painful disorder. In this lesson, you're going to learn what it is in simple terms as well as what its causes and treatments might be.

Mesentery: Medical Definition & Function

18. Mesentery: Medical Definition & Function

In this lesson, you will learn about the mesentery, its functions, its characteristics, and its classifications. You will also become familiar with the difference between true mesenteries and specialized mesenteries.

Epiploic Appendix: Definition & Functions

19. Epiploic Appendix: Definition & Functions

Although appendices is part of the term, the epiploic appendices (appendages) are not the appendix! Find out what they are in this lesson and what roles some believe they play in our body.
