Haematopoetic components Flashcards
where does erythropoiesis (red blood cell production) occur
bone marrow (pluripotent stem cells)
what do pluripotent stem cells develop to
Myeloid progenitor (become blood cells)
or
lymphoid progenitor (become lymphoid cells)
what is the function of erythrocytes
contain haemoglobin that bind to oxygen and carry it around the body.
and carry carbon dioxide for excretion
which cells produces platelets
megakaryocyte
what are reticulocytes
immature red blood cells
what are functions of neutrophils
tissue repair
phagocytic
which blood cell is not found in the blood
macrophages
how are macrophages developed
monocytes leave the blood and develop into macrophages in tissue
how to identify eosinophils under the microscope
very pink due to staining
function of eosinophils
helminth (soil transmitted) infection
allergy
most abundant white blood cells
neutrophils
how to identify monocytes
large nucleus
human kidney shape
how to identify basophils
large cytoplasmic granules that block the nucleus
not very abundant
what are the functions of mast cells
release histamines (activating factors) for wound release
what percentage of white blood cells are neutrophils
60%
