Respiratory System Functions and Disorders Quiz

Alveoli facilitate gas exchange in the lungs.

The primary role of the respiratory system is to exchange gases, primarily oxygen and carbon dioxide, with the external environment.

The larynx, or voice box, houses the vocal cords and is involved in speech production and protecting the airway during swallowing.

Bronchitis is often caused by viral infections, leading to inflammation of the bronchial tubes.

Respiration is the physiological process of gas exchange, involving inhalation of oxygen and exhalation of carbon dioxide.

Rhinitis refers to inflammation of the nasal passages, often associated with the common cold or allergies.

The respiratory system is not involved in hormone production; its primary functions include gas exchange, breathing, and sound production.

Diabetes is not a respiratory disorder; it is a metabolic disorder affecting blood sugar levels.

Dyspnea refers to difficulty or discomfort in breathing.

The epiglottis acts as a flap to prevent food from entering the windpipe during swallowing, directing it toward the esophagus.

A persistent cough is a common symptom of pneumonia, along with fever, chest pain, and difficulty breathing.

A persistent cough is a common symptom of asthma, along with wheezing, shortness of breath, and chest tightness.

Gas exchange in the lungs is termed respiration, where oxygen is taken in and carbon dioxide is expelled.

The trachea, also known as the windpipe, connects the larynx to the bronchial tubes, allowing air passage to and from the lungs.

Emphysema is a type of COPD characterized by damage to the air sacs in the lungs.

Bronchial asthma involves inflammation and constriction of the airways, leading to breathing difficulties.

Pneumothorax is the presence of air in the pleural cavity, which can cause lung collapse.

Exposure to air pollution, such as cigarette smoke or environmental pollutants, increases the risk of developing COPD.
