 '''血液'''は、[[humans/ja|ヒト]]をはじめとする[[vertebrate/ja|脊椎動物]]の[[circulatory system/ja|循環系]]にある[[body fluid/ja|体液]]であり、[[nutrient/ja|栄養]]や[[oxygen/ja|酸素]]などの必要な物質を[[cell (biology)/ja|細胞]]に送り、同じ細胞から[[Metabolic waste/ja|代謝廃棄物]]を運び出す。

+血液は[[blood plasma/ja|血漿]]中に浮遊する血球で構成される。血漿は血液液の55％を占め、その大部分は水分（体積比92％）であり、[[protein/ja|タンパク質]]、[[glucose/ja|グルコース]]、ミネラル[[ion/ja|イオン]]、[[hormne/ja|ホルモン]]を含む。血液細胞は主に[[red blood cell/ja|赤血球]]（赤血球）、[[white blood cell/ja|白血球]]（白血球）、（哺乳類では）[[platelet/ja|血小板]]（血小板）である。最も豊富な細胞は赤血球である。これらは[[hemoglobin/ja|ヘモグロビン]]を含んでおり、ヘモグロビンは酸素と可逆的に結合することで酸素の溶解度を高め、酸素輸送を促進する。[[Gnathostomata/ja|顎脚脊椎動物]]は、主に白血球に基づく[[adaptive immune system/ja|適応免疫系]]を持っている。白血球は感染症や寄生虫に抵抗するのに役立つ。血小板は血液の[[Coagulation/ja|血液凝固]]に重要である。
