Why do you need red blood cells?

Answer 1

Red blood cells are vital in our bodies because they are solely responsible for delivering oxygen to the organs in our body. If we didn't have any red blood cells, we wouldn't last 5 seconds because our organs will shut down due to oxygen deprivation.

Red blood cells contain an important component called Hemoglobin. This protein contains iron and carries oxygen. The lungs play an important role because they allow oxygen to diffuse into the blood cells. The blood cells are then pumped along with the rest of the blood throughout the body where they transfer the oxygen to each of our organs.

Answer 2

Because the white blood cells fight diseasesWhenever a germ or infection enters the body, the white blood cells snap to attention and race toward the scene of the crime. The white blood cells are continually on the lookout for signs of disease. When a germ does appear, the white blood cells have a variety of ways by which they can attack. Some will produce protective antibodies that will overpower the germ. Others will surround and devour the bacteria.by Olivia rose Thomson ( u can call me OLIVE) haha
