A Digital Resource on the Histology of the Excretory System

Welcome to this digital resource on the histology of excretory system. This resource is designed to aid your

mastery of the excretory histology by allowing you to revisit the material presented during lab. The material

presented here corresponds with the material presented during lab. In fact you will need your lab exercise, the

Histology of Excretory System to progress through this digital resource. We hope you find this material helpful.

However it should not take the place of slide observation in the laboratory. To fully appreciate histological

detail and completely explore a slide of the excretory system you should observe the slide through the

microscope. Also all slide tests involve histology presented through the microscope.
