Answer: Blood plays a very important role before cellular respiration. The blood provides oxygenated blood for the aerobic processes that takes place during cellular respiration. Glycolysis, link reaction, Kreb's Cycle and Electron Transport Chain are all the aerobic process of Cellular respiration that requires oxygen.

After cellular respiration the waste materials are carried away by blood only.
Hence, blood plays an important role before cellular respiration.
