Answer 1

Blood does not technically reach very cell red blood cells are mearly vessels for oxygen which is then “absorbed” by the area that it is flowing through due to the fact tens of millions of cells die and are made in the body it is not necessary for “blood to reach the cells” hence cells dying and new ones replacing them
