1. A Digital Resource on the Histology of the Respiratory System Welcome to this digital resource on the histology of respiratory system. This resource is designed to aid your mastery of the respiratory 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 Respiratory 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. For you to fully appreciate histological detail and completely explore a slide of the respiratory system you should observe the slide through the microscope. Also all slide tests involve histology presented through the microscope.
