GENERAL HISTOLOGY

Detailed explanation-1: -It takes in food from the esophagus (gullet or food pipe), mixes it, breaks it down, and then passes it on to the small intestine in small portions. The entire digestive system is made up of one muscular tube extending from the mouth to the anus. The stomach is an enlarged pouch-like section of this digestive tube.

Detailed explanation-2: -The cecum is the pouch-like beginning of the large intestine.

Detailed explanation-3: -Stomach. The stomach wall produces gastric juice (hydrochloric acid and enzymes) that digests proteins. The stomach acts like a concrete mixer, churning and mixing food with gastric juice to form chyme-a thick, soupy liquid.

Detailed explanation-4: -Esophagus: The esophagus is a muscular tube that connects the pharynx (throat) to the stomach. The esophagus contracts as it moves food into the stomach. A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach.

Detailed explanation-5: -The cells responsible for producing the HCl in the stomach are the parietal cells. It helps in the production of hydrochloric acid and certain enzymes that aid in the process of digestion of food.
