Ch 3: Human Circulatory System Study Guide

About This Chapter

The Human Circulatory System chapter of this Human Biology Study Guide course is the most efficient way to study the circulatory system. This chapter uses simple and fun videos that are about five minutes long, plus includes lesson quizzes and a chapter exam to ensure you understand the essential concepts of the human circulatory system.

Who's It For?

Anyone who needs help learning or mastering human circulatory system material will benefit from the lessons in this chapter. There is no faster or easier way to learn about the circulatory system. Among those who would benefit are:

  • Students who want to learn a broad topic in a short amount of time
  • Students who are looking for easy ways to identify the most important information on the topic
  • Students who have fallen behind in memorizing anatomy and physiology of the human circulatory system.
  • Students who prefer multiple ways of learning human biology (visual or auditory)
  • Students who have missed class time and need to catch up
  • Students who have limited time to study for an upcoming exam

How It Works:

  • Watch each video in the course to review all key topics
  • Refer to the video transcripts to reinforce your learning.
  • Test your understanding of each lesson with a short quiz.
  • Complete your review with the Human Circulatory System chapter exam.

Why It Works:

  • Study Efficiently: The lessons in this course cover only information you need to know.
  • Retain What You Learn: Engaging animations and real-life examples make topics easy to grasp.
  • Be Ready on Test Day: Take the Human Circulatory System chapter exam to make sure you're prepared.
  • Get Extra Support: Ask our subject-matter experts any human biology question. They're here to help!
  • Study With Flexibility: Watch videos on any web-ready device.

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.

The Cardiac Cycle: Phases, Explanation & Terms

3. 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.

Heart Rate, Cardiac Output & Stroke Volume

4. 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

5. 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.

Regulation of Blood Pressure: Short Term Regulation & Baroreceptors

6. Regulation of Blood Pressure: Short Term Regulation & Baroreceptors

Blood pressure in your blood vessels is closely monitored by baroreceptors; they send messages to the cardio regulatory center of your medulla oblongata to regulate your blood pressure minute-by-minute. In this lesson, you will learn how baroreceptors regulate your short-term blood pressure.

Total Peripheral Resistance & Blood Flow Regulation

7. Total Peripheral Resistance & Blood Flow Regulation

Blood flows continually through your heart and blood vessels. As the needs of the body change, blood flow needs to increase or decrease. Learn how vasodilation, vasoconstriction and other factors change the amount of resistance within your blood vessels to change blood flow through your body.

Functions of the Lymphatic System

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

9. 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

10. 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.

Blood Coagulation and Wound Healing

11. 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.

Atrioventricular Septum: Definition, Function & Development

12. Atrioventricular Septum: Definition, Function & Development

The heart is a very intricate machine with many essential parts. In this lesson, we will learn about the atrioventricular septum. Specifically, we will explore its definition, function, and development.

Atrioventricular Node: Definition, Function & Role

13. Atrioventricular Node: Definition, Function & Role

The atrioventricular node, also known as the AV node, plays a critical role in the electrical conduction of our heart. Read this lesson to learn more about where this special node is located and the important function it has.
