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¦
Chief Cells. The other type of exocrine secretory cell in the stomach is the chief cell. Chief cells secrete digestive enzymes that cleave the proteins in food into smaller pieces. The main enzyme secreted by chief cells is pepsin.he stomach is an organ of the digestive system. The inner wall of the stomach contains small pores called gastric pits. These pits contain cells that secrete chemicals that digest food. The two main types of exocrine secretory cells of the stomach are parietal cells and chief cells.
