Respiratory System and Thoracic Injuries Quiz

Alveoli facilitate the exchange of oxygen and carbon dioxide between the lungs and bloodstream.

The diaphragm contracts during inspiration, causing the lungs to expand and air to be drawn in.

Oxygen is carried by red blood cells, binding to hemoglobin for delivery to tissues.

Expiration is the process of exhaling air from the lungs, releasing carbon dioxide.

Atelectasis involves the collapse of alveoli, leading to reduced lung function and breathing difficulties.

The trachea carries air to and from the lungs, allowing for respiration.

Bronchitis involves inflammation of the bronchial tubes, leading to coughing and difficulty breathing.

The medulla oblongata regulates involuntary functions including breathing rhythm.

Pneumothorax involves the presence of air or gas in the pleural cavity, causing lung collapse.

Temperature regulation is not a primary function of the respiratory system.

Open pneumothorax allows air to enter the pleural cavity, leading to potential lung collapse and requiring urgent treatment.

The diaphragm separates the thoracic and abdominal cavities, aiding in breathing and organ function.

COPD involves chronic inflammation and narrowing of the airways, leading to breathing difficulties.

Asthma involves inflammation and constriction of the airways, leading to breathing difficulties and wheezing.

Flail chest can lead to respiratory failure due to compromised lung function and inadequate ventilation.
