Pre-Nursing Smarter - Respiratory System Workbook

Introduction

• The Respiratory System Workbook is available for free download from Pre-Nursing Smarter.
• Covers 10 key concepts and topics likely to appear in the T-Science section.

Key Topics and Questions

1. Ventilation

• Question: What is the mechanical process of taking air into the body?
• Answer: Ventilation.

2. Importance of Surface Area in Lungs

• Question: Why is surface area important in the lungs?
• Answer:
  • Increased surface area leads to increased diffusion (gas exchange) of oxygen and carbon dioxide.
  • Alveoli, grape-like sacs in the lungs, increase surface area.

3. Epiglottis

• Question: Which structure, when swollen, blocks the flow of air into the trachea?
• Answer: Epiglottis.

4. Site of Diffusion

• Question: Where is the site of diffusion?
• Answer: Alveoli.

5. Breathing Control

• Question: What structure in the brain controls breathing and what does it monitor?
• Answer:
  • Structure: Medulla oblongata.
  • Function: Monitors carbon dioxide levels in the blood.

6. Cystic Fibrosis

• Question: What condition causes mucus in the lungs and salty skin?
• Answer: Cystic Fibrosis.
  • Genetic condition affecting the lungs.
  • Important pathology for the T-Science section.

7. Emphysema

• Question: What condition is marked by ruptured alveoli?
• Answer: Emphysema.
  • Caused by smoking, environmental pollution.
  • Environmental damage to the lungs.

8. Changes to Air

• Question: What happens to air as it passes from the mouth and into the bronchioles?
• Answer: Air is warmed and moisturized.

9. Muscles Involved in Breathing

• Question: Which two groups of muscles are involved in the mechanical act of breathing?
• Answer:
  • Diaphragm.
  • Intercostal muscles.
  • Encourage deep breathing to alleviate stress and enhance relaxation.

10. Inspiration Pressure

• Question: What type of pressure causes an inspiration?
• Answer: Negative pressure.
