Ch 18: Circulatory System Structure & Function

About This Chapter

Accessing these convenient lessons on the structure and function of the circulatory system can help you with test preparation or a class project. You can review the anatomy of the heart, blood coagulation, the lymphatic system, and more from a mobile-friendly platform.

Circulatory System Structure & Function - Chapter Summary

In this chapter on the structure and function of the circulatory system, engaging lessons cover subjects like the flow of blood through heart chambers and blood vessels that carry blood away from the heart. There's also a discussion about how your blood type is determined. After going through the lessons, you should be able to do the following:

  • Identify chambers and valves in the heart
  • Define systole and diastole
  • List the advantages of a double circulatory system
  • Explain how blood travels throughout the body
  • Provide details about major blood vessels that feed the upper body
  • Recall why mature blood cells have mitochondria
  • Discuss clotting factors involved in wound healing
  • Describe the vital role of the lymphatic system

Our instructors are skilled at helping you understand the circulatory system. If you find yourself struggling with a topic, you can submit questions to these experts. A short quiz is available for each lesson to test your understanding of the concepts covered. Each video is accompanied by a full written transcript, which can be used as an entirely text-based learning option.

Anatomy of the Heart: Blood Flow and Parts

1. Anatomy of the Heart: Blood Flow and Parts

In this lesson, you will take a look inside the heart and identify the chambers and one-way valves that make up this vital organ. You will also follow along as we trace the flow of blood through the heart chambers.

Systole: Definition & Measurement

2. Systole: Definition & Measurement

This lesson defines what the term systole means and how it occurs in the body. We will take a brief look at the function of the heart in order to fully understand what is happening during systole. After reading the lesson, there is a short quiz to check your knowledge.

Diastole: Definition & Importance

3. Diastole: Definition & Importance

We are going to discuss what diastole means and when it occurs. You will learn about the importance of diastole. There will be a quiz to check your understanding after the lesson.

Double Circulation: Definition & Advantage

4. Double Circulation: Definition & Advantage

Humans and many other organisms use a double circulatory system. This means that we have two separate circuits for blood in our body. Learn how these circuits differ and the function of each one.

How Blood Travels Throughout the Body

5. How Blood Travels Throughout the Body

This lesson is going to cover the different blood vessels that carry blood throughout the body. The route and changes in blood pressure will also be discussed. A short quiz will follow.

Major Blood Vessels That Carry Blood Away From the Heart

6. 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.

Circulatory System IV: Red Blood Cells

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.

Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups

8. Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups

You are either blood type A, B, AB or O. But, did you know that your blood type is determined by microscopic antigens found on your red blood cells? In this lesson, you will learn about the different blood groups and why they do not mix.

Blood Coagulation and Wound Healing

9. Blood Coagulation and Wound Healing

When your blood vessels suffer damage, your body follows a sequence of events to promote blood clotting. In this lesson, you will learn about coagulation cascade and important clotting factors involved in wound healing.

Functions of the Lymphatic System

10. Functions of the Lymphatic System

In this lesson, you will learn about the lymphatic system and the vital role it plays in keeping the cardiovascular system working. You'll discover how the lymphatic system (with its lymphatic vessels and capillaries) quietly works in the background to return leaked fluids back to the blood.
