Ch 38: Prentice Hall Biology Chapter 38: Digestive and Excretory Systems

About This Chapter

The Digestive and Excretory Systems chapter of this Prentice Hall Biology course helps students learn the essential science lessons associated with the human digestive and excretory systems. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Digestive and Excretory Systems textbook chapter.

How It Works:

  • Identify the lessons in the Prentice Hall Biology Digestive and Excretory Systems chapter with which you need help.
  • Find the corresponding video lessons within this companion course chapter.
  • Watch fun videos that cover the digestive and excretory systems topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, re-watch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn about:

  • The dietary importance of water
  • Carbohydrates, lipids and proteins
  • Minerals
  • The upper and lower gastrointestinal tracts
  • The pancreas
  • The gallbladder and liver

Water's Role as a Nutrient: Importance & Dietary Need

1. Water's Role as a Nutrient: Importance & Dietary Need

Water is an important thing for the entire world and the world inside your body. This lesson will point out why it's important for you and how much you need on a daily basis.

Structure and Function of Lipids

2. Structure and Function of Lipids

Molecules called lipids have long hydrocarbon chains that determine the way they act. They can be fats, oils, or hormones, and even exist in our cell membranes. Learn more about the chemical structure and biological function of various lipids in this lesson.

Primary Functions of Protein in the Body

3. Primary Functions of Protein in the Body

Protein is a vital molecule that carries out many functions in your body. Learn how proteins provide structure, regulate body processes, transport materials throughout your body, help your immune system and act as a source of energy.

Structure and Function of Carbohydrates

4. Structure and Function of Carbohydrates

Carbohydrates are found in many foods that we eat and may be found as sugars, starches, or fiber. Learn more about these three distinct types of carbohydrates, and how they are distinguished through their chemical structures in this lesson.

Minerals in Our Food: Functions in the Body & Food Sources

5. Minerals in Our Food: Functions in the Body & Food Sources

Minerals are important substances that help your body's form and function on many different levels. This lesson will go over some important ones, what they do, and where they are found in our diets.

Vitamins We Need: Their Importance & Sources

6. Vitamins We Need: Their Importance & Sources

There are a lot of different vitamins, and they come from many different places! This lesson will teach you about what they are, how many different kinds you need, what they do, and where you can obtain them naturally.

Digestive System I: The Upper Gastrointestinal Tract

7. 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

8. 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.

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

9. 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

10. 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.

Excretory System

11. Excretory System

Each year in the U.S., close to 400,000 people with kidney failure undergo dialysis treatment in order to remove waste, remove excess fluid and restore electrolyte balance. Kidneys, the workhorses of the excretory system, perform these same functions more effectively than any machine. In this lesson, we'll talk about how the excretory system removes toxic substances from the body.

The Kidney: Major Divisions & Structures

12. The Kidney: Major Divisions & Structures

Learn about the major layers of the kidneys, like the renal cortex and renal medulla. Find out about the inner parts of the kidneys, including the renal papilla, renal pelvis, renal pyramid, and renal hilum.

Human Skin: Layers, Function & Structure

13. Human Skin: Layers, Function & Structure

This lesson will cover the three main layers of your skin, which includes the epidermis, dermis, and subcutis. In addition, we'll learn about other skin cells and tissue, such as adipose tissue, keratinocytes, melanocytes, and Merkel's cells.
