Which structures and organs of the pig digestive system develop as tubes or chambers within its tubular tract?

Tubes:

- Oesophagus: This is a muscular tube lined with mucous membrane involved in transferring chewed food from the mouth to the stomach.

- Small Intestine: Composed of the duodenum, jejunum, and ileum, the small intestine is where the major part of digestion and nutrient absorption occurs.

- Large Intestine: Consisting of the cecum, colon, and rectum, the large intestine plays a crucial role in water absorption, the formation of feces, and the elimination of waste.

Chambers:

- Stomach: The stomach is a J-shaped organ that serves as a temporary reservoir for food. It secretes gastric juices and churns the food to initiate digestion.

- Cecum: Located at the junction of the small and large intestines, the cecum is a pouch-like structure that hosts beneficial bacteria involved in the fermentation of plant matter.
