11.3 Chapter Questions - Disorders of Respiratory System

Question 1

What Is the function of the tonsils?

Answer 1

• Act as the first line of defense by trapping and filtering bacteria, viruses, and other pathogens.
• Produce antibodies
• Aid in the development of the immune system

Question 2

How does bronchitis affect a person’s ability to breath?

Answer 2

• Bronchitis inflames and narrows the airways.
• Excessive mucus production obstructs airflow.
• Symptoms include coughing, wheezing, and difficulty breathing.

Question 3

What is bronchoscopy and how is it a useful tool for diagnosing respiratory disorders?

Answer 3

• Bronchoscopy is a procedure using a thin tube called a bronchoscope to examine the airways and lungs.
• It helps diagnose respiratory disorders by directly visualizing the airways, identifying abnormalities, and collecting samples for analysis.
• It can detect tumors, inflammation, infections, or blockages in the airways.
• Bronchoscopy guides treatment decisions and can remove foreign objects or excess mucus.
• It is a valuable tool for accurate diagnosis and guiding appropriate treatment.

Question 4

What is spirometry and how is it a useful tool for diagnosing respiratory disorders?

Answer 4

• Spirometry is a diagnostic test that measures lung function and airflow.
• It helps diagnose respiratory disorders like asthma, COPD, and restrictive lung diseases.
• By assessing lung volume and airway obstruction, it guides treatment plans and monitors effectiveness.
• Spirometry provides objective data for clinical decision-making.

Question 5

Asbestosis, which causes pulmonary fibrosis, is a serious, chronic, non-cancerous respiratory disease. Inhaled asbestos fibers aggravate the lung tissue causing scar tissue to form. Scarred lung tissue loses its elasticity and gets thicker. Predict three symptoms that an individual with asbestosis would display and why the person would have each symptom. .

Answer 5

• alveoli scarred: difficulty breathing
• they are usually fixed in a larger position, meaning breathing out is going to be more difficult than breathing in
• acting as if they are almost always full
• making the vidal capacity is reduced on both ways
• fatigue
• sore muscles
• no wheezing
• pain from scarring

Question 6

An injury to the chest wall can cause the chest cavity to fill with air, resulting in a collapsed lung. Predict how the residual volume in an individual who has suffered such an injury would compare with the residual volume in a healthy individual.

Answer 6

• diaphragm drops = lung fills up because it reduced the pressure
• the pressure is gone due to the puncture, making the lungs collapse
• residual volume is lower
