About This Chapter
The Circulatory System - Chapter Summary and Learning Objectives
Get a comprehensive look at the circulatory system's processes and structure through these engaging and quick video lessons. You'll explore the major blood vessels that carry blood to and from the heart as well as special circuits, the human vascular system and the thoracic and abdominal aorta. Each lesson is taught by a subject expert who breaks down the circulatory system into small chunks that are fun to watch and easy to remember. As you make your way through these lessons, you'll be able to:
- Describe the different types of circulatory systems
- Differentiate between arteries, veins and capillaries
- Identify the blood vessels that travel between the heart and the lungs
- Explain the different layers of blood vessels
- Evaluate hemoglobin and red blood cells

1. The Human Circulatory System: Parts and Functions
In this lesson, you will take a ride on the transportation system of the body called the circulatory system and its two parts: the pulmonary circuit and the systemic circuit. Take a look inside and see how every inch of your body receives the oxygen and nutrients it needs.
2. 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.
3. 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?
4. 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.
5. 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.
6. 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)!
7. Blood Vessels: Arteries, Capillaries & More
In this lesson, you will take a trip around the circulatory system and encounter the various blood vessels, including arteries, veins, and capillaries. Come along as we follow the path to every cell of your body.
8. Blood Vessel Layers: Tunica Intima, Tunica Media & Tunica Adventitia
In this lesson, you will take a microscopic look at the three layers, or tunics, that make up your blood vessels. Follow along and learn how the different cells within these tunics help the vessels contract and relax as blood moves through your circulatory system.
9. Major Blood Vessels Between the Heart and Lungs: Pulmonary Trunk, Arteries & Veins
In this lesson you will learn about the main blood vessels that travel between the heart and lungs. You will also discover that these arteries and veins follow a somewhat unusual pattern.
10. Major Blood Vessels That Carry Blood Away From the Heart
Do you know which arteries are typically blocked during a heart attack? In this lesson, you will learn about the major blood vessels that feed the heart, brain and upper body. Then, find out what causes the pain known as angina.
11. Major Blood Vessels: Descending Aorta - Thoracic and Abdominal Aorta
The aorta is the largest artery of your body, and it is a strong and sturdy vessel. In this lesson, you will learn about its downward path through the chest and abdomen and discover the organs and structures supplied by its branches.
12. Major Blood Vessels Leading to the Heart: Superior Vena Cava, Inferior Vena Cava & Coronary Sinus
In this lesson, you will learn about the main blood vessel that returns blood to the heart called the Venae Cavae. You'll also learn about its two sections: the Superior and Inferior Vena Cava. You will then discover the special drainage system for the heart called the Coronary Sinus.
13. Special Circuits in the Circulatory System
In this lesson, we'll discuss why it's important for you (but not for an insect) to have a closed circulatory system. We'll discuss your systemic circuit and your pulmonary circuit and how each works together to get oxygen where it needs to go.
