About This Chapter
The video lessons in this chapter provide an overview of the components and functions of five major systems in the human body: circulatory, respiratory, digestive, excretory, and musculoskeletal. Each short video lesson brings the body system to life, with engaging animations and concrete explanations.

This chapter provides an overview of the major systems. Topics include:
- The different types of connective tissue
- The parts of the skeletal and muscular system and how they are related
- The types of circulatory systems in different organisms
- Details on the human vascular system
- An overview of the heart and how it works
- The role of red blood cells and hemoglobin
- How gas exchange works in the respiratory system
- The upper and lower gastrointestinal tracts of the digestive system
- An overview of the excretory system

1. Multicellular Organisms, Tissues and Epithelium
In this lesson on multicellular organisms, you'll take a look at what it actually means to be multicellular and how cells are organized into tissues, organs, and organ systems. This lesson also covers one of the four main tissue types: epithelial tissue.
2. Types of Connective Tissue
In this lesson, you'll learn about the various types of connective tissues in the body. These tissues include bone, fat, cartilage and blood. They form the framework of the body, support organs and much, much more!
3. Skeletal System and Muscular System
Do you know how many bones are in the human body? Check out this video lesson to uncover the answer, as well as understand the role and importance of the skeletal and muscular systems.
4. Circulatory System I: Types of Circulatory Systems
From cnidarians to humans, all animals need a circulatory system to absorb nutrients and get rid of waste. Find out why different kinds of animals have different systems, and see what a closed circulatory system and indoor plumbing have in common.
5. 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?
6. Circulatory System III: The Heart
What purpose does the heart serve? And how do different types of hearts function? In this lesson, you'll learn about two, three and four-chambered hearts.
7. Circulatory System IV: Red Blood Cells
Why don't mature red blood cells have nuclei or mitochondria, and how do these guys squeeze through capillaries? While learning about the brief but glorious lives of red blood cells, you'll also see which characteristics help them transport oxygen and carbon dioxide to other cells.
8. Circulatory System V: Hemoglobin
Did you ever wonder how red blood cells can store enough oxygen to supply the entire human body? Join us in this lesson on hemoglobin to learn why red blood cells are so good at transporting oxygen and carbon dioxide. This lesson will make you see red (as well as blue and purple-maroon)!
9. Gas Exchange in the Human Respiratory System
Did you know that the average human lung has a respiratory surface area that is roughly the same size as half of a tennis court? Believe it or not, that's how much surface area an active, healthy human needs to ensure that the body gets plenty of oxygen.
10. 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.
11. 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.
12. 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.
