Ch 8: Digestive System: Tutoring Solution

About This Chapter

The Digestive System chapter of this College Anatomy & Physiology Tutoring Solution is a flexible and affordable path to learning about the digestive system. These simple and fun video lessons are each about five minutes long and they teach all of the information about the digestive system required in a typical anatomy & physiology course.

How it works:

  • Begin your assignment or other anatomy & physiology work.
  • Identify the digestive system concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our college anatomy & physiology tutoring solution will benefit any student who is trying to learn about the digestive system and earn better grades. This resource can help students including those who:

  • Struggle with understanding the anatomy and physiology of the mouth, esophagus, stomach, intestines, pancreas, gallbladder and liver or any other digestive system topic
  • Have limited time for studying
  • Want a cost effective way to supplement their biology learning
  • Prefer learning biology visually
  • Find themselves failing or close to failing their digestive system unit
  • Cope with ADD or ADHD
  • Want to get ahead in anatomy & physiology
  • Don't have access to their biology teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about the digestive system simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live anatomy & physiology tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about the digestive system on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

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.

Chymotrypsin: Definition, Structure & Mechanism

16. Chymotrypsin: Definition, Structure & Mechanism

Chymotrypsin is an enzyme used for digesting proteins. In this lesson we will learn what types of proteins it digests and how it digests those proteins.

Chymotrypsin: Uses & Functions

17. Chymotrypsin: Uses & Functions

The body uses several enzymes to digest food. One of these enzymes, chymotrypsin, is for digesting proteins. We will learn about this and other uses of chymotrypsin outside of digestion.

The Difference Between Trypsin & Chymotrypsin

18. The Difference Between Trypsin & Chymotrypsin

Trypsin and chymotrypsin are two very similar enzymes that perform similar functions. In this lesson we will explore how they are different and what in the structure causes the difference.

Trypsin: Definition, Function & Mechanism of Action

19. Trypsin: Definition, Function & Mechanism of Action

Trypsin is one of the enzymes used to digest proteins. It is very similar to another protein digestion enzyme, chymotrypsin. In this lesson we'll learn more about trypsin, what it does, and how it works.
