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.
All four tissue types are present in the stomach. The stomach is lined with EPITHELIAL type cells (simple columnar). Beneath the epithelial cells there is CONNECTIVE type tissue.Beneath this you will find (smooth) MUSCLE cells. There is also NERVOUS type tissue present in the wall of the stomach (myenteric and submucosal plexus).eneath the epithelial cells there is CONNECTIVE type tissue. Beneath this you will find (smooth) MUSCLE cells. There is also NERVOUS type tissue present in the wall of the stomach (myenteric and submucosal plexus).
