Answer: Mild low levels are common and usually harmless. They are especially common in people of African descent. if the decrease is more than mild and persistent or accompanied by other symptoms or abnormalities it may warrant further evaluation. The white cells fight infection so, besides being a sign of another problem, low levels can lead you to get sick easily.
Answer: Which white blood cell? The three most common methods of fighting infections are: production and release of antibodies, phagocytosis (surrounding and digesting), and chemotherapy (the granules of some white blood contain chemicals). White blood cells are capable of traveling to an area of infection.
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.
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.
