血液1マイクロリットルに含まれる成分である:
One microliter of blood contains:
* '''4.7~6.1&nbsp;万個(男性)、4.2~5.4&nbsp;万個(女性)[[erythrocyte/ja|赤血球]]''' 赤血球は血液の[[hemoglobin/ja|ヘモグロビン]]を含み、酸素を分配する。成熟した赤血球には、哺乳類では[[Cell nucleus/ja|]][[organelle/ja|オルガネラ]]がない。赤血球は([[endothelial/ja|内皮]]血管細胞やその他の細胞とともに)、異なる[[Human blood group systems/ja|血液型]]を規定する[[glycoprotein/ja|糖タンパク質]]によっても特徴づけられる。赤血球が占める血液の割合は[[hematocrit/ja|ヘマトクリット]]と呼ばれ、通常は約45%である。人体のすべての赤血球の表面積を合わせると、人体の外表面のおよそ2,000倍になる。
* '''4.7 to 6.1&nbsp;million (male), 4.2 to 5.4&nbsp;million (female) [[erythrocyte]]s:''' Red blood cells contain the blood's [[hemoglobin]] and distribute oxygen. Mature red blood cells lack a [[Cell nucleus|nucleus]] and [[organelle]]s in mammals. The red blood cells (together with [[endothelial]] vessel cells and other cells) are also marked by [[glycoprotein]]s that define the different [[Human blood group systems|blood types]]. The proportion of blood occupied by red blood cells is referred to as the [[hematocrit]], and is normally about 45%. The combined surface area of all red blood cells of the human body would be roughly 2,000 times as great as the body's exterior surface.
* '''4,000~11,000個の[[leukocyte/ja|白血球]]''' 白血球は身体の[[immune system/ja|免疫系]]の一部であり、古くなった細胞や異常な細胞、細胞の残骸を破壊・除去し、感染因子([[pathogen/ja|病原体]])や異物を攻撃する。白血球のがんは[[leukemia/ja|白血病]]と呼ばれる。
* '''4,000–11,000 [[leukocyte]]s:''' White blood cells are part of the body's [[immune system]]; they destroy and remove old or aberrant cells and cellular debris, as well as attack infectious agents ([[pathogen]]s) and foreign substances. The cancer of leukocytes is called [[leukemia]].
* '''20万~50万個の[[thrombocytes/ja|血小板]]''' [[platelet/ja|血小板]]とも呼ばれ、血液凝固([[coagulation/ja|凝固]])に関与する。凝固カスケードからのフィブリンが[[platelet plug/ja|血小板栓]]の上に網目を作る。
* '''200,000–500,000 [[thrombocytes]]:''' Also called [[platelet]]s, they take part in blood clotting ([[coagulation]]). Fibrin from the coagulation cascade creates a mesh over the [[platelet plug]].
