Pathologies of the Respiratory System - Chapter Summary and Learning Objectives

The video lessons in this chapter deal with the lungs and other parts of the respiratory system. You'll get a look at the anatomy and function of each structure and learn about the conditions and diseases that can affect respiration. This chapter is designed to teach you:

  • The anatomy and physiology of the respiratory system
  • How respiratory acidosis and alkalosis occur
  • About chronic obstructive pulmonary disease (COPD) and its causes and treatments
  • Causes of restrictive lung disease
  • Causes and treatment of tuberculosis, pulmonary embolism and cystic fibrosis

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

1. 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.

Function of Pleural Cavities and Pleural Membranes

2. Function of Pleural Cavities and Pleural Membranes

Each lung is contained within a pleural cavity, the space between the outside of the lung and inside of the chest wall. Pleural membranes cover the outside of the lungs and line the inside of the chest wall. The lungs remain expanded when we breathe due to a vacuum effect within the pleural cavity.

Carbon Dioxide Transport in the Blood

3. Carbon Dioxide Transport in the Blood

While carbon dioxide is a metabolic waste product, it plays some important physiological roles as well. This lesson describes how carbon dioxide is transported in our blood, how carbon dioxide is converted into a pH buffer, and how carbon dioxide helps with oxygen transport.

Respiratory Acidosis: Causes and Regulation

4. Respiratory Acidosis: Causes and Regulation

This lesson will discuss an important relationship between the kidneys and the lungs and how both of them play a role in respiratory acidosis. We'll also discuss some of the major causes of respiratory acidosis.

Respiratory Alkalosis: Causes and Regulation

5. Respiratory Alkalosis: Causes and Regulation

This lesson will discuss a condition called respiratory alkalosis. We'll define and compare alkalosis vs. alkalemia as well as what may cause respiratory alkalosis and how it may be controlled.

The Causes of Chronic Obstructive Pulmonary Disease (COPD)

6. The Causes of Chronic Obstructive Pulmonary Disease (COPD)

This lesson explores the causes of obstructive lung disease, including COPD, emphysema, and chronic bronchitis. We'll also discuss asthma, cystic fibrosis, and bronchiectasis.

Pneumothorax and Atelectasis: Similarities, Differences & Causes

7. Pneumothorax and Atelectasis: Similarities, Differences & Causes

This lesson will discuss two conditions, both of which are sometimes called a collapsed lung, that have some similarities and some major differences. These two conditions are known as pneumothorax and atelectasis.

Extrinsic Causes of Restrictive Lung Disease

8. Extrinsic Causes of Restrictive Lung Disease

Did you know that air can actually cause you problems breathing? It's true. Find out in this lesson how air, fluid, fat, and all sorts of other stuff causes difficulty breathing.

Intrinsic Causes of Restrictive Lung Disease

9. Intrinsic Causes of Restrictive Lung Disease

What does popcorn have to do with lung disease? Well, this lesson will help you find out as we venture into the world of the intrinsic causes of restrictive lung disease.

Conditions Associated with Respiratory Failure

10. Conditions Associated with Respiratory Failure

This lesson will discuss two causes of respiratory failure, one of which occurs in adults and one of which occurs in infants. You'll also find out how too much alcohol can lead to one of these respiratory problems.

Tuberculosis: Diagnosis, Treatments & Latency

11. Tuberculosis: Diagnosis, Treatments & Latency

This lesson will discuss the disease known as tuberculosis. We will talk about mycobacterium tuberculosis, latent TB, TB disease, mycolic acid, and the symptoms, signs, and treatments used for this terrible disease.

Bacterial Pneumonia: Causes, Signs & Treatments

12. Bacterial Pneumonia: Causes, Signs & Treatments

This lesson will discuss the causes of bacterial pneumonia. We'll also look into how bacterial pneumonia is diagnosed and treated as well as the common signs and symptoms associated with this condition.

Viral and Fungal Causes of Pneumonia

13. Viral and Fungal Causes of Pneumonia

This lesson will discuss two causes of pneumonia: viruses and fungi. We'll go over some of the main agents that cause these types of pneumonia and how viral and fungal pneumonia differ from bacterial pneumonia.

Pulmonary Embolism: What is it and Why Does it Occur?

14. Pulmonary Embolism: What is it and Why Does it Occur?

This lesson will discuss a condition known as deep vein thrombosis, including the three main reasons for its formation, as well as its very famous and deadly complication: a pulmonary embolism.

Lung Cancer: Causes, Signs & Treatments

15. Lung Cancer: Causes, Signs & Treatments

Lung cancer is actually one big term for many different types of cancers. This lesson will help you understand how lung cancer is classified based on its origins and appearance.

Cystic Fibrosis: Cause, Progression, and Treatment

16. Cystic Fibrosis: Cause, Progression, and Treatment

This lesson will discuss a genetic disorder called cystic fibrosis as well as it how it affects the respiratory and digestive system, the ways by which it can be diagnosed, and treated.

The Lungs and the Heart: One Affects the Other

17. The Lungs and the Heart: One Affects the Other

This lesson discusses how the heart and lungs may cause one another problems when one or the other becomes sick or damaged. Namely, we will discuss something known as cor pulmonale and pulmonary edema.
