Digestive System I: The Upper Gastrointestinal Tract

1. Digestive System I: The Upper Gastrointestinal Tract

Did you know that there are digestive enzymes in your saliva? It's true. As soon as you put a piece of food in your mouth, the digestive process begins. Join us with this first of two lessons about the human digestive system, where we'll follow food through the upper gastrointestinal tract from the mouth through the stomach.

Digestive System II: The Lower Gastrointestinal Tract

2. Digestive System II: The Lower Gastrointestinal Tract

The lower gastrointestinal tract is the part of the digestive system that is responsible for the last part of food digestion and the expulsion of waste from the body. In this lesson, we'll look at each part of the system and what functions each serves in the process of digestion.

Anatomy and Physiology of the Mouth

3. 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

4. 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.

Physiology of the Stomach and Gastric Juices

5. 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.

Anatomy and Physiology of the Stomach and Autonomic Nervous System Controls

6. 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.

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.

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

8. 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.

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.

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

10. 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.

Anatomy and Physiology of the Large Intestine

11. 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

12. 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.
