1. Observe the urine sediment images in Figure 27-9 in order to detect the presence of leukocytes, epithelial cells, mucus threads, bacteria, casts, and various crystals.

2. Table 27-1 shows abnormal components of urine, disorders, and their possible causes.

3. Identify the abnormal components in each of the urine sediment images A,B, C, and D and name the disorder associated with the presence of the components and the possible causes of the presence of the components in the urine samples.
