Question
Chapter 26.2, Problem 14WDYL
Summary Introduction
To determine:
The secretory cell types in the stomach along with their products and functions of the products.
Concept introduction:
The stomach is present just below the diaphragm and in the upper left region of the abdomen. Stomach mixes the ingested food with gastric secretions and digests the food into semi-fluid chime. Stomach consists of some secretory cells whose secretion helps in the digestion process.
