Document Summary
Cellular level: cell in the stomach lining . Tissue level: layers of tissue in the stomach wall : cells of similar structure and specialized function combine to form tissues. Cardiac muscle pumps blood from the heart. Smooth muscle controls movement of contents through hollow tubes and organs. Consists of cells specialized for initiation and transmitting electrical impulses. Electrical impulses act as signals that are important in communication, coordination, and control in the body. Consists of cells specialized for exchanging materials between the cell and its environment. Any substance that enters or leaves the body must cross an epithelial barrier. Connects, supports, and anchors various body parts. Loose connective tissue attaches epithelial tissue to underlying structures. Bone gives the body shape and support. Organ level: the stomach : composed of two or more types of primary tissue. Body system level: the digestive system : digestive.
