This unit will provide students with the foundation knowledge of pathology by gaining an understanding of the fundamental processes that occur when the human organism undergoes disturbance of its homeostasis. They will gain an appreciation of the ‘one health’ concept of the interrelationships between humans and other living things and their shared environment impacting on human health. The Unit incorporates pathological processes such as cell injury and death, inflammation, healing and neoplasia. Students will gain an understanding of the basic cellular and molecular functions of the immune system in health and disease. Students will be introduced to the range of microorganisms infecting humans and the microbiome, which appears to protect against a growing number of diseases. Students will also learn how the immune system can sometimes be dysregulated and cause significant pathology (immunopathology). Laboratory practical classes will introduce students to basic immunology and pathology techniques that will reinforce material presented during lectures.
