Classify any epithelium by layers and shape, name where each type lines the body and why, and tell tight, anchoring and gap junctions and the three modes of secretion apart.
Unit 3 carries 4 of Zoology's 40 marks across four chapters, so expect about one question on epithelium, occasionally two, because a location table is the easiest thing in the unit to set. MEC's scope line is a single phrase: "Structure, location and function". Questions come as recall ("which epithelium lines the trachea?"), understanding ("why are alveoli lined by flat cells?") and application, where a slide is described in words and you name the site, or a change is described (cilia paralysed by smoke) and you predict the consequence. Learn the location table cold, then the reasons behind it.

Connective Tissue: Fibres, Cartilage, Bone and the Fluids That Bind
Sort any connective tissue into proper, supporting or fluid, name its cells, fibres and matrix, and say where hyaline, elastic and fibrocartilage, compact and spongy bone, blood and lymph are found and why.
