Which of the following is associated with the structure marked as "$X$"?

Digestion and Absorption

Solution:

The marked structure (X) is stomach. Stomach is the most distensible and widest organ of the alimentary canal which is differentiated into four parts - cardiac fundic and pyloric part. It acts as a food reservoir and helps in mechanical churning and chemical digestion of food. Caecum is a small blind sac which hosts some symbiotic microorganisms. The undigested, unabsorbed substances enter into the caecum of large intestine through ileo-ceacal valve which prevents the back flow of the faecal matter.
