Circulatory System I: Types of Circulatory Systems

1. 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.

Circulatory System II: The Human Vascular System

2. 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?

Circulatory System III: The Heart

3. 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.

Circulatory System IV: Red Blood Cells

4. 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.

Circulatory System V: Hemoglobin

5. 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)!
