The Human Cardiovascular System - Blood & Heart - Chapter Summary and Learning Objectives

Heart disease is prevalent in our society today. There are many forms of heart disease and many problems that can affect your heart and circulatory system. Heart trouble can cause a range of other health issues, too. Without this powerful muscle and all its components working properly, a person cannot live a full life. In this chapter, we will focus on studying the cardiovascular system, including an in-depth look at the heart. You'll see how this system works and how it might fail. Some of the things you'll get to study in these lessons include:

  • The phases of the cardiac cycle
  • What happens when the heart beats
  • Types of heart conditions
  • How blood flow in the heart is regulated
  • What's important about the red blood cells

VideoObjective
The Human Circulatory System: Parts and Functions Study the parts and functions of the circulatory systems, including closed circulatory, double circulation, pulmonary circuit, systemic circuit, heart, blood vessels and blood.
Anatomy of the Heart: Blood Flow and Parts Take an in-depth look at the heart and learn about the atrium, ventricle, mitral valve, tricuspid valve, semilunar valves, aorta, vena cava pulmonary arteries and pulmonary veins.
The Cardiac Cycle: Phases, Explanation & Terms Explore the cardiac cycle.
Heartbeat and Heart Contraction Coordination Examine how the heart works.
Electrocardiogram (ECG): Definition & Wave Types Discover what an ECG is.
Arrhythmia of the Heart: Terms, Definition & ECG Detection Analyze arrhythmia of the heart, including bradycardia, tachycardia, flutter, fibrillation and heart block.
Types of Heart Conditions and Diseases Look at common types of heart conditions, such as heart attack, coronary heart disease and congestive heart failure.
Heart Rate and Blood Flow Regulation Examine stroke volume, flow rate, vascular resistance, end-diastolic volume and end-systolic volume.
Regulation of Blood Pressure: Short Term Regulation & Baroreceptors Find out more about how blood pressure is regulated.
Functions of the Lymphatic System Discover how the lymphatic system functions.

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.

What Is the Composition of Blood?

2. What Is the Composition of Blood?

This lesson is going to cover the materials of which blood is composed. We will explore the parts that make up the solid and liquid portions of blood and discuss how these are maintained.

What Are Blood Cells? - Functions & Types

3. What Are Blood Cells? - Functions & Types

There are three different types of blood cells circulating through the bloodstream. Learn about the function of each of the three types of blood cells, and test your knowledge by taking the quiz.

Carbon Dioxide Transport in the Blood

4. Carbon Dioxide Transport in the Blood

While carbon dioxide is a metabolic waste product, it plays some important physiological roles as well. This lesson describes how carbon dioxide is transported in our blood, how carbon dioxide is converted into a pH buffer, and how carbon dioxide helps with oxygen transport.

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

5. 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.

Rh Blood Group, Rh Factor & Erythroblastosis Fetalis

6. Rh Blood Group, Rh Factor & Erythroblastosis Fetalis

Rh factor is a red blood cell antigen found in most people. Those with Rh factor are Rh positive, while those without are Rh negative. In this lesson you will learn about Rh blood compatibility and its importance during pregnancy.

Anatomy of the Heart: Blood Flow and Parts

7. 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.

The Cardiac Cycle: Phases, Explanation & Terms

8. The Cardiac Cycle: Phases, Explanation & Terms

In this lesson, you will learn what happens during each heartbeat, or cardiac cycle. You will also learn that the heartbeat involves periods of relaxation and contraction, known as diastole and systole, respectively.

Heartbeat and Heart Contraction Coordination

9. Heartbeat and Heart Contraction Coordination

In this lesson you will learn about your heart's very own regulatory system, the intrinsic conduction system, and how it sets the pace for a normal, healthy heartbeat. You will discover that your heart moves to its own beat thanks to the natural pacemaker of the heart called the SA node.

Heart Rate, Cardiac Output & Stroke Volume

10. Heart Rate, Cardiac Output & Stroke Volume

The amount of blood your heart pumps is constantly changing to meet the needs of your body. In this lesson, you will learn how the heart maintains an adequate cardiac output, heart rate and stroke volume.

Regulation of Heart Rate and Stroke Volume

11. Regulation of Heart Rate and Stroke Volume

The amount of blood being pumped through your body changes constantly due to the demands of daily life. In this lesson, you will learn how your body adjusts the heart rate and stroke volume to increase or decrease blood flow.
