What is the primary purpose of a bronchoscopy?

The primary purpose of a bronchoscopy is to conduct an endoscopic examination of the bronchial tubes. During a bronchoscopy, a healthcare provider uses a specialized instrument called a bronchoscope, which is a thin tube equipped with a camera and light, to visualize the airways and lungs. This procedure allows for the assessment of various conditions affecting the bronchial passages, including infections, blockages, or abnormalities such as tumors or inflamed tissue. Additionally, bronchoscopy can facilitate the collection of tissue samples for biopsy and enable the removal of foreign objects or mucus plugs within the airways.

The other options do not accurately represent the primary function of bronchoscopy. Performing a lung transplant is a complex surgical procedure that requires different techniques and skills. Removing a lung tumor may necessitate surgical interventions outside of what a bronchoscopy offers. Similarly, assessing heart function typically involves tests like echocardiograms or cardiac catheterizations rather than bronchoscopy, which is specifically concerned with the observation of the bronchial and pulmonary structures.
