    Does blood “take out the trash too”, i didnt realize it serves that dual function. Like I knew it transports oxygen and maybe nutrients vaguely…

      It sure does! Blood is carried back to the spleen, kidney, and liver where the blood is “cleaned” of the waste it was carrying before being recirculated. It also carries immune cells to/from your lymph nodes, oxygen, water, all sorts of stuff. Blood is more than just WBC/RBC!
