Basophilic granulocytes in the peripheral blood

have brick-red granules.

are usually about 8 to 10 µm in diameter.

their basophilic granules in the cytoplasm are larger than those of other granulocytes.

have a double-lobed, sometimes S-shaped or irregularly segmented nucleus.

Leukocytes in the peripheral blood

are physiologically present in the blood of adults at a frequency of 15,000 to 40,000 leukocytes/mm3.

some are short-lived, e.g. neutrophils normally survive only hours to days.

some memory cells can survive for months to years.

can pass from the bloodstream into the connective tissue.

during their differentiation, specific granules are formed, the presence of which allows us to distinguish the type of granulocyte formed in the myelocytes (neutrophilic, basophilic, eosinophilic).

are characterized by a spherical, unsegmented nucleus (called mononuclears).

arise from precursor cells, myeloblasts.

are exemplified by monocytes and NK cells (natural killer cells).

Hynek's nuclear number

expresses the amount (mass) of hemoglobin in the erythrocyte.

is the average number of nuclear segments in neutrophils.

is approximately 2.7 in a healthy individual.

represents the average nuclear volume of erythroblasts (in femtolitres).

von Willebrand factor.

eosinophil cationic protein (ECP).

gives rise mainly to erythrocytes.

develops from the megakaryoblast.

gives rise to platelets.

is usually about 100 µm in size.

still has a nucleus, which is ejected from the cell in the next stage of development.

continues to develop into a reticulocyte, of which there are normally only a limited number in circulation (1-2% of erythrocytes).

circulates in the blood and normally penetrates the blood vessel wall into the connective tissue of most organs, where it carries oxygen directly to the cells.

is an erythrocyte with a diameter of approximately 7.2-7.5 µm.

Erythrocytes (red blood cells) in the peripheral blood

are non-nucleated and have no rough endoplasmic reticulum, which allows them to survive for hours or days at most.

transport oxygen and carbon dioxide, both bound to haemoglobin.

their small fraction (up to 10% of erythrocytes), which still has nuclei, are called reticulocytes.

thanks to their flexible membrane cytoskeleton, they can deform reversibly and thus penetrate even small capillaries.

Of all the white blood cells in the peripheral blood, in a healthy person they usually form

20 - 30% lymphocytes.

65 - 75% neutrophils.

2 - 5% eosinophils.

4 - 8% monocytes.

A low hematocrit may be caused by

excessive production of erythropoietin.

prolonged occult bleeding, e.g. in the intestine.

sudden and rapid blood loss.

dehydration of the body.
