All organs consist of two or more tissues that must work together to enable the organ to function properly. The study of the tissues that make up the body's organs is called organology. Most organs are made of layers of tissues stacked upon one another and "glued" together by proteins and other compounds in the ground substance. This exercise introduces you to organology, a topic we explore repeatedly in the remainder of this lab manual. Procedure 1: Determine the Tissue Types of Organs. Following are illustrations of two organs: a joint and the esophagus (Fig. 5.12). Tissue sections from each organ have been taken, and your task is to identify each tissue. Be specific about which type of muscle, epithelial tissue, and connective tissue you identify in the organ. When you have completed the procedure, answer Check Your Understanding question 6 (p. 132).
Organ A: a joint; Organ B: the esophagus
