Ch 22: The Cardiovascular System

About This Chapter

Watch video lessons about the human cardiovascular system and how it functions. Each well-illustrated video includes a helpful self-assessment, which can demonstrate how well you understood the material.

The Cardiovascular System - Chapter Summary and Learning Objectives

The cardiovascular system is really the 'heart' of life science, for humans; learn more about the components of the cardiovascular system through a series of video lessons led by a qualified life science teacher. Get an overview of the circulatory system, the lymphatic system, and circulatory system as a whole. At the end of this chapter, you should be able to:

  • Summarize the parts and functions of the human circulatory system
  • Discuss the anatomy of the heart, lymphatic system, and blood
  • Explain the concept of blood type and why it matters
  • Describe types of heart conditions and diseases

Video Objective
The Human Circulatory System: Parts and Functions List the parts of the circulatory system, and describe how they work, individually and together.
Anatomy of the Heart: Blood Flow and Parts Describe the parts of the heart and how they function.
Types of Heart Conditions and Diseases Identify types of health conditions related to the heart, including coronary heart disease and congestive heart failure.
Functions of the Lymphatic System Describe the lymphatic system, and its role in the cardiovascular system.
Blood: Function and Components Define blood; explain its role in the cardiovascular system and what it's made of.
Circulatory System IV: Red Blood Cells Summarize the structure and function of the circulatory system, and describe the role of red blood cells.
Blood Types: ABO System, Red Blood Cell Antigens and Blood Groups Explain what blood types are, and what those designations mean.

The Human Circulatory System: Parts and Functions

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.

Anatomy of the Heart: Blood Flow and Parts

2. 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.

Types of Heart Conditions and Diseases

3. Types of Heart Conditions and Diseases

Your heart muscle receives a rich blood supply from the coronary arteries. If the coronary arteries become blocked, it can result in coronary heart disease, angina, heart attack or congestive heart failure. Learn how these conditions get started.

Functions of the Lymphatic System

4. 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.

Blood: Function & Components

5. Blood: Function & Components

You know your heart pumps blood through your blood vessels, but do you know why this is important? Learn why your blood must keep moving, as well as the things that make it up, like plasma, red blood cells, white blood cells and platelets.

Circulatory System IV: Red Blood Cells

6. 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

7. 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.
