Students Will Review:
This chapter summarizes the material students need to know about the circulatory system for a standard human biology course. Topics covered include:
- Parts and functions of the circulatory system
- Anatomy of the human heart and blood vessels
- The cardiac cycle
- Heart rate and cardiac output
- Measures and regulation of heart and blood vessel functions
- Blood flow regulation
- Lymphatic system physiology
- Blood cell antigens and blood types
- Coagulation and wound healing
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. 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
