What white blood cell has the longest life span?
Lymphocytes. They need to stick around as memory to fight reoccuring infections.
If all cells in your body start out life with the same inherited information on how to build proteins then what caused the differences between a red blood cell and a white one Between a white blood?
Actually red blood cells do not have the longest life span of circulating blood cells - that would be differentiated memory B lymphocytes. RBCs actually have a relatively short circulating life span (about 4 months on average) because they lose their nuclei and most cellular organelles when they mature. This means the cell cannot repair damage to the cell membrane and eventually the cell becomes too damaged to function and is removed by the spleen.
Your body benefits when a white blood cell kills a cell that has been infected by a virus because the cells that was infected is no longer able to infect other cells with the bacteria. If the cell is not killed the virus in the cell will infect other cells. this may cause diseases that can be life threatening.
Red Blood Cell- 120 days life span White Blood Cell- The lifespan of white blood cells ranges from 13 to 20 days, after which time they are destroyed in the lymphatic system. Platelets- usually 10 -12 days These numbers do not include the amount of time it takes for them to mature in the bone marrow. It only reflects the time they live in the blood stream.
A human red blood cell... 100 to 120 days. Other (smaller) mammal's red blood cells... a little less than half that of a human's. A human white blood cell... 13 to 20 days. A human's t-cells... appears to be on the order of a year (or more). A mouse's native alpha or beta t-cell... a minimum of 8 weeks.
* Red blood cells do not have a nucleus (to save space and allow for higher amounts of haemoglobin), whereas white bloody cells do. * White blood cells protect the body from diseases (either by digesting the 'problem' or by emission of antibodies), whereas red blood cells are simply a means of transporting oxygen and other gases. * Red blood cells tend to have a life span of about 4 months, while white blood cells…
The spleen is not necessary for life but does have important functions: 1. Defense -macrophages lining sinusoids of spleen remove microorganisms from blood and phagocytose (eat) them. 2. Hematopoiesis -monocytes (white blood cell) and lymphocytes (white blood cell) complete their development in the spleen. 3. Red blood cell and platelet destruction-macrophages remove worn-out RBCs and imperfect platelets and destroy them by phagocytosis (eating); also salvage iron and globin from destroyed RBCs 4. Blood reservoir -pulp…
If you're talking about which phase of mitosis takes longest (as in, Interphase, Prophase, Metaphase, Anaphase or Telophase) then Interphase is by far the longest, taking up as much as 90% of the cycle. Or if you mean which phase of the cell life cycle (as in, G1, synthesis, G2, M phase/mitosis) then G1 is the longest stage.
White blood cells flow in the blood together with red blood cells. White blood cells are not stored in any particular place in the body because they have a short life span, therefore, the body is constantly producing fresh white blood cells. Like red blood cells, white blood cells are produced in the bone marrow.
Enzymes called caspases aid in programmed cell death, known as apoptosis. Apoptosis occurs when a cell is at the end of its normal reproductive life or when it has been damaged. At this time, the cell receives information that initiates a series of events that lead to its own destruction. After apoptosis, white blood cells engulf the degraded cell fragments.
There are actually more red blood cells than white blood cells in your body. The difference has mainly to do with their life cycle. You actually produce more white blood cells per day than red blood cells, but the white ones have a much shorter life, from a few days to a few weeks, while the red blood cells can live for 3-4 months.
