Muscle cells from the stomach have a characteristic tear-drop shape with a grainy cytoplasm containing mitochondria and a nucleus. Describe the function of these cells in the wall of the stomach

These muscle cells are known as a type of cell called smooth muscle. They serve to contract/shorten regularly in unison in a process known as peristalsis. This allows the food to be mixed with each other, as well as with digestive enzymes to help break it down.
