3.Blood function RBC 一 carry oxygen via hemoglobin from lungs to peripheral tissues and carbon dioxide away from peripheral tissues to lungs reticulocyte:number increases in hemolytic anemia,decreases in aplastic anemia,radiation and chemotherapy
• RBC – carry oxygen via hemoglobin from lungs to peripheral tissues and carbon dioxide away from peripheral tissues to lungs – reticulocyte: number increases in hemolytic anemia, decreases in aplastic anemia, radiation and chemotherapy 3. Blood function
3.Blood function ● WBC leucocytes are an important part of the body's immune system and also have a role in inflammation,allergic responses,and protect against pathogens,abnormal cells (cancer cells), remove toxins and wastes
• WBC – leucocytes are an important part of the body's immune system and also have a role in inflammation, allergic responses, and protect against pathogens, abnormal cells (cancer cells), remove toxins and wastes 3. Blood function
3.Blood function 。Neutrophils -phagocytize and provide a first line of defense in acute infections increase in bacterial infection phagocytize bacteria and fungi release antimicrobial chemicals
• Neutrophils – phagocytize and provide a first line of defense in acute infections – increase in bacterial infection – phagocytize bacteria and fungi – release antimicrobial chemicals 3. Blood function
3.Blood function 。lymphocytes lymphocytosis:viral infections,antigen stimulation lymphocytopenia:early stages of bacteria infection
• lymphocytes – lymphocytosis: viral infections, antigen stimulation – lymphocytopenia: early stages of bacteria infection 3. Blood function
3.Blood function ·Monocytes increase in viral infections and inflammation differentiate into macrophages and dendritic cells in the tissue phagocytize pathogens and debris -"present"antigens to activate other immune cells take part in tissue repair
• Monocytes – increase in viral infections and inflammation – differentiate into macrophages and dendritic cells in the tissue – phagocytize pathogens and debris – “present” antigens to activate other immune cells – take part in tissue repair 3. Blood function
