About This Chapter
The Human Circulatory System - Chapter Summary
This chapter is designed to present a clear picture of the human circulatory system and how it works with the lungs. In these lessons, you will find overviews of the circulatory and respiratory systems and detailed information about specific structures in each of these systems. After you have completed your review of this chapter, you should be able to:
- Identify major parts and functions of the circulatory system
- Explain how the circulatory and respiratory systems work to bring oxygen and nutrients to the body
- Name and describe the function of different types of blood vessels
- Discuss the function of the atrium of the heart
- Describe the solid and liquid portions that make up blood
Using simple language and helpful illustrations, these lessons make it easy to learn about these human body systems. Lessons are easily accessible at any time, on any device, making it convenient to fit studies into any schedule. Self-assessment quizzes help you determine whether you have achieved mastery of the material or need to continue your review.
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. Blood Vessels: Arteries, Capillaries & More
In this lesson, you will take a trip around the circulatory system and encounter the various blood vessels, including arteries, veins, and capillaries. Come along as we follow the path to every cell of your body.
3. 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.
4. Atrium: Heart Function & Definition
The atrium is a key player in the functioning of the heart, yet it does not get the attention it's due when compared to the ventricles. This lesson pays homage to this unsung hero in cardiac circulation.
5. Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones
The respiratory system includes the lungs as well as other organs that help to get oxygen into the blood and carbon dioxide out of the blood. The conducting zone of the respiratory system carries oxygen into the lungs and carbon dioxide out of the lungs. The respiratory zone is where oxygen and carbon dioxide move into and out of the blood.
6. 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.
