Ch 10: Respiratory System Basics

About This Chapter

Improve your understanding of respiratory system basics, including amphibian respiratory systems, gross anatomy of the lungs, and more. If you are preparing for an exam or class discussion, these lessons and quizzes will help boost your confidence by testing your knowledge of the topics in advance.

Respiratory System Basics - Chapter Summary

In these lessons on respiratory system basics, you will review gross anatomy of the airway. You will also gain an understanding of the significant size of your lungs' respiratory surface area. By the end of the chapter, you should feel confident and prepared to:

  • Discuss the respiratory systems of amphibians, birds, and mammals
  • List organs that help get oxygen into the blood
  • Describe gas exchange in the human respiratory system
  • Recall the interaction of oxygen and hemoglobin in gas transport
  • Explain the process of external and internal respiration in the lungs

A brief quiz is available for each lesson to test your understanding of respiratory system basics, and you can also contact our instructors with any questions. The quizzes link back to specific topics in the video, so, if you get a question wrong, you can quickly review that topic. Our instructors provide helpful illustrations in each lesson to assist you with grasping the concepts presented.

Amphibian, Bird & Mammal Respiratory Systems

1. Amphibian, Bird & Mammal Respiratory Systems

While something as basic as breathing may sound universal, the fact is that amphibians, birds, and mammals all do it differently. In fact, even humans can't always control their breathing.

Gross Anatomy of the Airway and Lungs: Conducting & Respiratory Zones

2. 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.

Gas Exchange in the Human Respiratory System

3. Gas Exchange in the Human Respiratory System

Did you know that the average human lung has a respiratory surface area that is roughly the same size as half of a tennis court? Believe it or not, that's how much surface area an active, healthy human needs to ensure that the body gets plenty of oxygen.

Gas Transport: Oxygen and Hemoglobin

4. Gas Transport: Oxygen and Hemoglobin

Did you know that almost all of the oxygen transported in our blood is bound to hemoglobin? Hemoglobin is loaded with oxygen in the lungs and unloaded of oxygen in the metabolizing tissues. This lesson will describe how oxygen is transported in our blood.

External and Internal Respiration in the Lungs: Definition & Process

5. External and Internal Respiration in the Lungs: Definition & Process

This lesson explores the process by which oxygen and carbon dioxide get into and out of the blood located in the lungs and in our metabolizing tissues. The partial pressure gradient for each gas determines both the direction and rate of diffusion across the respiratory membrane.
