Blood Flashcards
(15 cards)
Red blood cells
erythrocytes, contain hemoglobin (gas exchange)
White blood cells
leukocytes, immune response
Platelets
Thrombocytes, blood clotting
Granulocytes
neutrophils, eosinophils, basophils
Agranulocytes
monocyte, lymphocyte
Neutrophils
Abundance: 40-70% Function: phagocytize foreign material, can leave blood and go into tissue structure: 2x size of RBC -bands: immature neutrophil, “band” of nuclei (unsegmented) -segs: mature neutrophils, nuclei are segmented into 2-5 lobes increased during bacterial and fungal infections
Eosinophils
Abundance: 1-5% Function: phagocytic, function in parasitic infections (protozoa, helminths0 Structure: 2x size of RBC -2 lobed nucleus, red/organce cytoplasmic granules Increased: during parasitic infections, severe allergies
Basophils
Abundance: >1% Function: unknown, participate for an allergy response (produce histamine/heparin) Structure; 2x RBC -dark cytoplasmic granules -1-2 lobe nucelus (if seen) Increased: allergic response
Monocytes
Abundance: 2-6% Function: can migrate into tissue–> macrophage when mature (phagocytic) can be seen an antigen presenting cell Structure: 2-4X RBC, bean shaped nucleus, no granules Increased: viral infections
Lymphocytes
Abundance: 25-40% Function: adaptive immunity -T cells: cell mediated immunity -B cells: can become plasma cells: produce antibodies -Natural Killer cells: non-specific, kill foreign and infected cells Structure: 1-2x RBC -spherical nucleus that takes up most of the cell increased: Viral infections
