White blood cells are larger than red blood cells and contain less of them. When a person is infected with bacteria, the quantity of white cells in the body might skyrocket. In contrast, when a person is infected with a virus, the number of red blood cells can increase.
The average human wbc count is 5-10 million/ml while the average rbc count is 4-6 million/ml. A wbc count of more than 20 million/ml indicates an excessive amount of white blood cells while a rbc count of more than 10 million/ml suggests a possible internal bleeding problem. A person's red blood cell count can rise when they suffer from anemia (low blood count) or hemorrhage (bleeding into the bloodstream). A white blood cell count that is too high could be a sign of inflammation or infection.
In conclusion, white blood cells are larger than red blood cells.
In the event of an infection, white blood cells assault and eliminate the bacterium, virus, or other organism that is causing it. If this occurs too far beyond the number of red blood cells, you can become leukopenic (lack of white cells). Being leukopenic makes you vulnerable to infections that the body cannot fight off.
When someone has leukemia, their white blood cell production lines go wrong. They make too many or not enough white blood cells. In very rare cases, people with leukemia can also have a problem with their red blood cells or platelets. These other problems can occur because of difficulties in producing new white blood cells or difficulties in destroying old or damaged cells.
People who suffer from leukemia need to be treated with aggressive antibiotics until they are no longer infectious. After treatment has stopped, they need regular checks to make sure that their white blood cell count is still low enough to prevent infections occurring. If it rises above normal levels again, another round of treatment will be required.
In conclusion, leukemia means the cancerous change of bone marrow tissue. It is divided into two main types: acute and chronic. Acute leukemia is diagnosed when there are high numbers of white blood cells or blasts in the blood or bone marrow samples.
WBCs help fight infection by going to sites of injury or infection and searching for bacteria or other particles that may have caused the damage. They also help protect against cancer because they kill cells that are infected with viruses or have changed into cancerous cells.
Lymphocytes are a type of WBC and there are two main types: T cells and B cells. The T cell is responsible for helping the body fight off infections and cancers, while the B cell produces antibodies that can find and attack foreign particles such as bacteria and viruses. Both types of lymphocytes require stimulation by proteins on the surface of other cells in order to proliferate and produce more immune cells. This process is called "activation."
The term "white blood cell" comes from the color of these cells being similar to white meat birds. Blood cells are called "red blood cells" or "erythrocytes" because they contain hemoglobin, which gives them their red color.
WBCs are one of the most important parts of the immune system.
