Final answer:
Gastroscopy does not deal with the lungs. It is a procedure used to examine the stomach and diagnose conditions in the gastrointestinal tract.
Step-by-step explanation:
Gastroscopy does not deal with the lungs. Gastroscopy is a medical procedure that involves inserting a thin, flexible tube with a camera (endoscope) into the stomach to examine its lining and diagnose any abnormalities or conditions.
The lungs are part of the respiratory system, while the stomach and the entire gastrointestinal (GI) tract are part of the digestive system. The respiratory system is responsible for breathing and gas exchange, while the digestive system is responsible for the breakdown and absorption of food.
