During the chest examination of a patient by a stethoscope, the doctor observed some bubbling sounds that indicate the presence of fluid in the alveoli.The possible respiratory disease diagnosed by the doctor will be
Correct answer: D. Pneumonia
- A. Asthma
- B. Sinusitis
- C. Bronchitis
- D. Pneumonia
Explanation
The key terms in the question are 'bubbling sounds' and 'fluid in the alveoli.' These are characteristic of pneumonia, a condition where the alveoli become inflamed and fill with fluid or pus due to infection, causing sounds often described as crackles or rales during a stethoscope examination. Asthma involves airway constriction and wheezing, not fluid in the alveoli. Sinusitis affects the nasal sinuses, not the lungs. Bronchitis involves inflammation of the bronchial tubes, which may cause coughing and mucus, but does not typically lead to bubbling sounds in the alveoli.

About Human Respiratory System
The human respiratory system conducts air to the alveoli, where oxygen and carbon dioxide exchange occurs across thin respiratory surfaces. Questions cover the nasal passage, trachea, bronchi, lungs, diaphragm and intercostal muscles, ventilation mechanics and gas transport, while distinguishing breathing and gaseous exchange from cellular respiration.
