red blood cells are replaced ever 120 days, so therefore are replaced 3 times a year
120 days
Red and white blood cells are both made in the marrow of the long bones.
in long bones
The human blood cell on average lives for apx. 120 days. once it dies it has to be replaced.
long bones in our body are the resorviour of red blood cells. There from bone marrow stem cells the red blood cells diffrentiate
90 to 120 days
It varies dramatically depending on what type of cell it is. For example, blood cells and skin cells are constantly being replaced, so they don't live for very long. However, your brain and nerve cells NEVER get replaced, so they live until you die. That's why if you hurt your spine in, for example, a car wreck, you are likely paralyzed for life, whereas if you scrape your skin it will grow back.
If by 'replaced' you mean, can the body grow new ones like with blood and tissue cells, then no, not at present. There is some promising research being done with stem-cell therapies, but they're a long way from being able to effectively regrow nerve tissue.
Bone marrow from long bones in your body contribute in producing the red blood cells at younger age.
Bone marrow is found in the long bones of the body and also in the pelvic bones. The long bones are the femur, which is the thigh bone and the humerus which is the upper arm bone. the pelvic bones are the hip bones. The center if these bones contain the marrow and this is where the red blood cells are made. Red blood cells transport oxygen around the body to all other cells. Red blood cells live for 120 days. They are destroyed in the spleen.
Cells that store nutrients are Fat Cell. the function of Fat cells are long term storage of nutrients for the body. Where: attached to bones by tendons. Cells are striated (cells contain alternating light and dark bands) Cells have more than one nucleus. Can be controlled voluntarily.
The bone marrow located inside the bone. It is present in the bones of the ribs and in the long bones of the body. It manufactures red blood cells and white blood cells. It is not an eatable.
