So if we zoom in on a small section of the lining we basically get the following microscopic diagram. So our exocrine glands consist of four important types of cells. We have mucous cells, we have chief cells, parietal cells and Gsels down all the way at the bottom of these ducts of our exocrine glands. Now, adjacent to our ducts we basically have our capillary system that connects to our blood vessels as well as to our lymph vessels and these vessels exchange waste products and bring nutrients and oxygen to the cells found on the lining of our stomach and the lining of these exocrine glands. Now below the blood vessels we have our muscle. We have a three layer muscle system that is responsible for contraction of the stomach and that ultimately allows the movement of our food from our stomach along the stomach and into our small intestine.
