在肺中，氧分子将自己吸附在驻留在红细胞上的血红蛋白分子上，然后传递氧气在细胞与细胞之间前进。Oxygenmolecules氧分子Hemoglobinmolecules血红蛋白Oncethecellshaveusedtheoxygenwhichhasbeendelivered,thecarbondioxidetheyhaveproducedarethentransportedbacktothelungsandexpelledinexhaledair.

当细胞将送达的氧气使用完毕时，它们产生的二氧化碳会被运回肺并随着呼出的气体被排出。Carbondioxide二氧化碳Expel驱逐，逐出Exhale呼出，发出Para.10Thebloodandlymphvesselconjunctionwiththedigestivesysteminorderforthecirculatorysystemtoperformthedeliveryofnutrition.血管和淋巴管与消化系统协同工作以确保循环系统发挥运用养分的作用Conjunction连接Cleansing净化Whenfoodiseatenitisbrokendownbythedigestivesystemandthenutrientsareabsorbedthroughthewalloftheintestines，whichisthenpickedbythebloodvesselandcarriedofftothecellsrequiringthenutritionwithapitstopthrongtheliverfornutrientabsorptionandtoxiccleaning.吃下的食物在消化系统分解，养分通过肠壁吸收后为血管获取并送到需要这些养分的细胞，期间肝脏将营养物质吸收并清除有毒物质。Thewastesassociatedwithexcesswaters,ions,plasma,andmetabolicwasteproducedbythecells,arethenfilteredthroughcapillarieswhichbelongtothekidneys.
