Some of the factors that affect the rate at which particles diffuse include: the particle's molecular weight, temperature, concentration difference, diffusion distance, permeability and surface area.
This region of the stomach is called the 'cardiac' region. How does the mucosa in this region change? Gastric Glands in the fundus (body) of the stomach. The epithelium of the mucosa of the fundus and body of the stomach forms invaginations called gastric pits. The lamina propria contains gastric glands, which open into the bases of the gastric pits. These glands are responsible for the synthesis and secretion of the gastric juice.
The gastric mucosa is the mucous membrane layer of the stomach which contains the glands and the gastric pits.In humans it is about 1 mm thick and its surface is smooth, soft, and velvety.he epithelial lining of the gland ducts is of the same character and is continuous with the general epithelial lining of the stomach. An important iodine concentration by sodium-iodide symporter (NIS) is present in mucinous cells of surface epithelium and gastric pits of the fundus and pyloric part of the stomach.
