P points to the tube that carries food from the pharynx to the stomach, which is the Oesophagus.

Q points to the upper, dome-shaped part of the stomach, which is known as the Fundus.

R points to the junction where the oesophagus meets the stomach, which is the Gastro-oesophageal junction (regulated by the gastro-oesophageal sphincter).

Therefore, P is Oesophagus, Q is Fundus, and R is Gastro-oesophageal junction.
