Cardiovascular System-Mariel Martinez Period 3 - Coggle Diagram

- - - - Platelets: fragements of larger megakarycotye, involved in blood clots process : Function: form temporary plate plug -->helps seal breaks in blood vessels with the help of Thrombopoiten: regulate platelet enlarge
      - WBC (leukocytes): complete with nuclei + organelles; normal response to infection; -Granulocytes: visible cytoplasmic granules (Neutrophils: first responders to infection; engulf and destroy bacteria
        Eosinophils: fight parasites and help control allergic reactions
        Basophils: involved in inflammation and allergies )
        
        Agranulocytes: no visible cytoplasmic granules
        (Lymphocytes: key cells of the immune system; produce antibodies and destroy infected cells
        Monocytes: largest WBCs; become macrophages that engulf pathogens and debris )
    - - Structure:small diameter (7.5), biconcave disc shape, annucleate, nor ogranelles Function:contribute to gas transport-->filled with hemoglobin
      - Production:Hematopoieses: formation of all blood cells; Erythropoiesis: form RBC, occurs in red bone marrow
      - Regulation and Requirements:Hormonal Control: Erythroprotein: stimulates formation of RBCs : always in small amounts as it maintains basal rate
- - - - Antigen: Rh (D) antigen present
      - Can receive Rh⁺ or Rh⁻ blood
    - - Antigen: no Rh antigen
      - Can receive Rh⁻ only
      - Can develop anti-Rh antibodies if exposed to Rh⁺ blood
