Lecture #16 Blood Flashcards
What is the life span of a typical erythrocyte?
120 days
What is the main stimulus for erythropoiesis?
Erythropoiesis is the synthesis of new red blood cells and hypoxia (O2 deficiency) stimulates this process.
What type of cell makes up 60 to 70% of leukocytes, has 2 to 5 lobes, and has a life span of 3 to 5 days?
A. Basophils B. Eosinophils C. Neutrophils D. Lymphocytes E. Monocytes F. Thrombocytes G. Keratinocytes H. Melanocytes I. Lymphocyte J. Langerhans Cell K. Plasma Cell L. Macrophage M. Mast Cell N. Fibroblast
C. Neutrophils
Which cell type responds quickest to bacterial infection?
A. Basophils B. Eosinophils C. Neutrophils D. Lymphocytes E. Monocytes F. Thrombocytes G. Keratinocytes H. Melanocytes I. Lymphocyte J. Langerhans Cell K. Plasma Cell L. Macrophage M. Mast Cell N. Fibroblast
C. Neutrophils
Which type of cell makes up 2 to 4 % of the circulating leukocytes, has a bilobed nucleus, and a life span of approximately 10 to 12 days?
A. Basophils B. Eosinophils C. Neutrophils D. Lymphocytes E. Monocytes F. Thrombocytes G. Keratinocytes H. Melanocytes I. Lymphocyte J. Langerhans Cell K. Plasma Cell L. Macrophage M. Mast Cell N. Fibroblast
