Understanding Blood, the Immune System, and Blood Doping

This text explores the interactions between blood and the immune system, focusing on the role of erythropoietin and antibodies produced by immune cells. It explains how antigens work, distinguishing between self and foreign molecules, particularly in Type A blood. The document covers the functions of macrophages, B cells, and T cells in creating antibodies and chemicals that combat disease. It also contrasts active immunity—where the body generates its own antibodies—versus passive immunity, where antibodies are received from another source.

Presentation Transcript

  1. Blood and the Immune System

  2. Blood Doping • Blood • Erythropoietin

  3. Antibody Protein made by cells in your immune system Binds to ‘foreign’ molecules called ANTIGENS

  4. In Type A blood , ‘A’ antigens are ‘self’ and ‘B’ antigens are ‘foreign’

  5. Specific Macrophage

  6. B Cells T Cells Make Antibodies Make Chemicals Kill Diseased Cells

  7. Active Immunity • Give Antibodies (from someone else who made them) • Passive Immunity • Given Antigen (make own antibodies)

  8. Barriers
