Answer: Red is not a problem, this simply means you can transport more oxygen around the body. A lot of doping in athletes does just this. You can also increase your red blood count by staying at high altitude.
White however is symptoms of infections. High count of white blood cells is normally used by medical personnel to check for infections.
Answer: There are a number of mechanisms for carbon dioxide transport in the blood, and which ones are used and to what extent depends on the level of CO2 in the blood. In normal conditions CO2 is picked up via the spent hemoglobin (which has discharged 1 or 2 of its four oxygen carrying sites) and carried back to the lungs for gas exchange as carbaminohemoglobin. As an aside, the pick up of CO2 by hemoglobin renders the hemoglobin less able to carry Oxygen, and has the affect of forcing additional remaining oxygen molecules off the hemoglobin and into the blood stream, making even higher amounts of oxygen available at the tissue level. Unlike Oxygen, Carbon Dioxide dissolves readily in blood. Should there be more CO2 in the blood than can be carried by the hemoglobin, the balance will for the most part be dissolved directly into the blood via the equation below, facilitated by an enzyme known as Carbonic Anhydrase:
This equation defines the role of carbonic acid as a buffer in the blood, keeping pH relatively constant in spite of continually changing acidic products levels in the blood (higher CO2 near the muscles, lower CO2 near the lungs). Note that excess bicarbonate (HCO3) and hydrogen ion (H+) concentrations are excreted by the kidneys, although in healthy circumstances these are recombined when CO2 is excreted during gas exchange in the lungs. This is a "short" version of a very complex and dynamic topic. There are many other buffers in the blood that provide back up assurance that pH does not become overly influenced by increases and decreases in CO2 as part of the normal respiratory cycle.
Answer: A raised white blood cell count can mean you have an infection in the body. A low red blood cell count could mean your bone marrow is not creating enough healthy red blood cells, which can lead to not getting enough oxygen circulating throughout the body.
Answer: White blood cells are cells of the immune system defending the body against both infectious disease and foreign materials. If you have a high white blood cell count it means your probably sick or fighting off a virus of some kind.
Answer: White blood cells perform a complex function, identifying and attacking invaders of the body. They need genetic information found in the nucleus to be able to do this correctly. Red blood cells perform a very simple function, transporting oxygen. Simply by containing hemoglobin, red blood cells do this automatically, so they do not need genetic information found in the nucleus. White blood cells have a complex function, requiring them to identify and attack invaders of the body. They need lots of genetic information to be able to do this. Red blood cells have a very simple function, to transport oxygen, which happens automatically because of the oxygen-binding compound hemoglobin that they contain, so they do not need any genetic information to be able to do that.
The only purpose that red blood cells have is to carry oxygen via hemoglobin throughout the body. The red blood cells are able to forgo all unnecessary organelles and be more efficient by having most of the cell fill up with hemoglobin while being formed in the bone marrow.
