Blood Components Flashcards
What is the primary function of Red Blood Cells (RBC)?
Assist with gas transport for aerobic respiration
RBCs are non-nucleated cells containing hemoglobin.
What type of cell is characterized as a segmented polymorphonuclear granulocyte?
Neutrophil
Neutrophils are involved in the defense system and are the first WBCs during inflammation.
What is the main function of Eosinophils?
Defense against parasites and allergic reactions
Eosinophils are segmented polymorphonuclear granulocytes.
What is the role of Basophils in the immune response?
Associated with allergic reactions
Basophils are also segmented polymorphonuclear granulocytes.
What is the function of Monocytes/macrophages?
Phagocytosis
Monocytes are large mononuclear phagocytes.
What types of immunity do Lymphocytes participate in?
Humoral and cell mediated immunity
Lymphocytes are mononuclear immunocytes.
What is the primary role of Natural Killer cells?
Defends against tumors and viruses
Natural Killer cells are large granular lymphocytes.
What is the primary function of Platelets?
Hemostasis
Platelets are cytoplasmic fragments.
What is the average lifespan of Red Blood Cells (RBC)?
80-120 days
What is the lifespan of Neutrophils?
4 days
How long can Monocytes/macrophages live?
Months to years
The lifespan depends on the type of cell.
What is the average lifespan of Lymphocytes?
Depends on type
Different types of lymphocytes have varying lifespans.
What is the lifespan of Platelets?
8-11 days
