Pathology

Pathology is the study of diseases and the changes they cause in the structure and function of the body. It involves the examination of organs, tissues, and bodily fluids to understand the causes and effects of diseases.

Types of Pathology

1. Anatomical Pathology: Involves the examination of tissues and organs to diagnose diseases through techniques such as biopsies and autopsies.
2. Clinical Pathology: Focuses on the analysis of bodily fluids such as blood and urine to diagnose diseases and monitor treatment.
3. Forensic Pathology: Investigates the cause of death in cases of criminal or suspicious circumstances.

Understanding Disease Processes

Pathologists study the cellular and molecular changes that occur in diseases, including inflammation, infection, and cancer. They also investigate the body's responses to these diseases, and how they affect different organs and systems.

1. Classification of diseases (infectious, genetic, autoimmune, neoplastic, etc.)
2. Understanding the cellular and molecular changes in diseases
3. Diagnostic techniques in pathology (biopsies, cytology, blood tests)
4. Role of pathology in treatment and management of diseases
5. Impact of diseases on different organs and systems
