    Study Notes

    Cell Death

    • Apoptosis is considered physiologic cell death.
    • The point of no return for affected cells is when caspases are activated.

    Biliary Atresia

    • Biliary atresia is a condition where the bile ducts are blocked, preventing bile from flowing into the intestines. This blockage can lead to liver damage and failure.

    Etiology in Pathology

    • Etiology refers to the cause of a disease or condition.

    Aplasia

    • Aplasia in pathology means the complete absence of an organ or tissue.

    Atresia

    • Atresia refers to the complete closure or absence of a normal body opening or passage. For example, biliary atresia is the absence of the bile ducts.

    Hypoplasia

    • Hypoplasia in pathology is the incomplete or underdeveloped formation of an organ or tissue. It is a less severe form of aplasia.

    Pathology

    • Pathology is the study of the causes and effects of diseases on living organisms.
    • In essence, it's about understanding the structure and function changes that occur in organisms due to disease.

    Basic Unit of Life

    • The basic unit of life is the cell.

    Focus of Pathology

    • Pathology focuses on studying the changes in cells and tissues associated with diseases.

    Significance of Pathology

    • Pathology plays a crucial role in understanding the mechanisms of disease, diagnosing illnesses, and developing new treatments.
