Ugereranyije, abagabo bakuze bakuze harimo hafi 5 (litiro 4,75) z'amaraso, agizwe na kimwe cya 3 (litiro 2,85) za plasma na quarti 2 (litiro 1.9) za selile.
Utugingo ngengabuzima twamaraso duhagarikwa muri plasma, igizwe namazi nibikoresho byashonze, harimo imisemburo, antibodies, na enzymes zijyanwa mumyenda, nibicuruzwa biva mu ngirabuzimafatizo bijyanwa mu bihaha no mu mpyiko.
Uturemangingo twinshi twamaraso dushyirwa mubice nka selile zitukura (erythrocytes), selile yera (leukocytes), na platine (trombocytes).
Ingirabuzimafatizo zitukura ni umubiri woroshye, uzengurutse, ucuramye urimo hemoglobine, imiti igoye itwara ogisijeni na dioxyde de carbone.
Hemolysis ibaho mugihe ururondogoro ruto rukingira ingirabuzimafatizo zitukura zacitse, bigatuma hemoglobine ihungira muri plasma.Hemolysis irashobora guterwa no gufata nabi urugero rwamaraso, ugasiga irushanwa kumara igihe kinini (bitera guhagarara kumaraso) cyangwa gukanda urutoki cyane mugihe cyo gukusanya capillary, kuyungurura, guhura nibihumanya, kurenza urugero mubushuhe, cyangwa mubihe byindwara.
