Paint the stripper onto a small area of your wall with a paintbrush and allow it to sit on the surface for about five minutes, unless otherwise instructed by the product's manufacturer instructions. Once the stripper has had time to work, scrape the loosened paint from the surface.imply scraping will remove the majority of loosened paint; small areas can be taken care of with fine-grit sandpaper fitted to a rotary or oscillating tool. Use only the flat edge of the scraper, or you could gouge the surface; if you do, fill in the damaged areas with joint compound.
function in digestive system. in gastric gland. The intermediate gastric glands produce most of the digestive substances secreted by the stomach. These glands are narrow tubules composed of three major cell types: zymogenic, parietal, and mucous neck cells. At the base of the gland are the zymogenic (chief) cells, which are thought to produce the enzymes pepsin and rennin. (Pepsin digests proteins, and rennin curdles milk.) Parietal, or oxyntic, cells occur throughout the length of the glandâ¦
There are four types of cells in the stomach: 1  Parietal cells: Produce hydrochloric acid and intrinsic factor. 2  Gastric chief cells: Produce pepsinogen. 3  Chief cells are mainly found in the body of stomach, which is the middle or superior anatomic portion of the stomach. It is produced by the stomach cells called chief cells in its inactive form pepsinogen, which is a zymogen. 2  Pepsinogen is then activated by the stomach acid into its active form, pepsin. 3  Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids.
