Students will review:
In this chapter, you'll learn the answers to questions including:
- What are the parts of the circulatory system, and how do they work?
- How does blood flow through the different parts of the heart?
- What types of medical conditions and diseases can affect the heart?
- How does the lymphatic system work?
- How are blood types categorized?
1. The Human Circulatory System: Parts and Functions
The human circulatory system has many parts that enable blood to move throughout the body. Learn about the circulatory system, how provides oxygen to cells, and explore the many other parts and functions, including the pulmonary and systemic circuits.
2. Anatomy of the Heart: Blood Flow and Parts
The heart is a complex organ that regulates a body's blood flow. Explore the anatomy of the heart and learn about its different parts, including the four chambers and heart valves, the heartbeat, as well as the process and importance of blood flow.
3. Types of Heart Conditions and Diseases
There are several types of heart conditions and disease. Learn about coronary arteries and the causes and symptoms of atherosclerosis, coronary heart disease, angina, heart attack, and congestive heart failure.
4. Functions of the Lymphatic System
A healthy lymphatic system is necessary for a properly functioning cardiovascular system. Learn about the lymphatic system (lymphatic capillaries, lymph nodes, lymph, lymphatic vessels, & lymphatic drainage), the functions of each structure within the lymphatic system, and how edema occurs if the lymphatic system fails to return leaked fluids to the blood.
5. Circulatory System IV: Red Blood Cells
Red blood cells are an important part of the circulatory system with only one job: to transport carbon dioxide and oxygen between the body's lungs and all other cells. Learn about this process and understand red blood cells, including how they are produced and how they function.
6. Blood Types: ABO System, Red Blood Cell Antigens & Blood Groups
Blood types are determined by antigens found in red blood cells. Learn about the blood types, red blood cell antigens, agglutination, the ABO system, the blood groups, and the definitions of universal donor and universal recipient blood types.
7. Coronary Heart Disease: Causes, Symptoms & Treatment
In this lesson, we will look at what causes coronary heart disease. We will learn about symptoms associated with this disease as well as treatment options.
8. Systemic Vascular Resistance: Definition & Formula
This lesson clearly explains the terms and concepts related to systemic vascular resistance, including alternative terms and formulas you might see in other textbooks. This way, you won't be confused!
