BLOOD OVER VIEW
Blood is a fluid that transfers oxygen and nutrients to cells while also removing carbon dioxide
and other waste materials. Blood is a transport liquid that is pumped by the heart (or a
comparable structure) to all areas of the body and then returns to the heart to resume the
process. Blood is a tissue as well as a fluid. It is classified as a tissue since it is made up of similar
specialized cells that perform certain roles. These cells are floating in a liquid matrix (plasma),
which is what gives blood its fluid consistency. If blood flow is interrupted, death will occur within
minutes due to the impact of an unfavorable environment on particularly vulnerable cells.
