    Red blood cells, also called erythrocytes, are responsible for the characteristic color of our blood. They are responsible for picking up carbon dioxide from our blood and for transporting oxygen. The essential component of red blood cells is hemoglobin, which can hold oxygen so the cells can then transport around the body. This process is what gives the body energy, which explains why people who suffer from anemia (low count red blood cells) often feel tired and sleepy. A high count of red blood cells is rare, but it can happen. Causes include kidney disease, dehydration, anabolic steroid use, and pulmonary fibrosis. People suffering from a high count of red blood cells usually have impaired circulation, and are at a high risk for heart disease. White blood cells or leukocytes, on the other hand, are primarily responsible for fighting foreign organisms that enter the body. This includes everything from bacterial and parasitic infections to allergic response. T-cells, a form of white blood cells, are the ones that stop functioning properly in the presence of an HIV infection. An overproduction of white blood cells can lead to leukemia.

    I think Red blood cells carry oxygen, while white cells do not. e.g. Red blood cells in humans do not have nuclei, while white cells do.
