I've been asking this very question myself, the best answers I could find related to donating blood. Apparently it takes 3-4 weeks to regrow the red blood cells lost in one pint of blood. the fluid itself is made up in less than 24 hours, and the iron takes longest to replace, at 8 weeks.
Interestingly enough, Wheatgrass is supposed to help stimulate the growth of red blood cells, although this is from a website trying to sell Wheatgrass, so who knows...
hope this helps!
yes
Well they don't grow back like blood cells do if that's what you mean buy "create".
put an eyebrow pencil to grow back fast
they wont grow back as fast they might not grow back at all because of the chemicals that have been on them.
Hair only grows so fast and nothing but time will get it back to where you want it.
As soon as you are cut, platelets in blood form fibers to cause a clot. Then White Blood Cells destroy any pathogens that entered the body when the cut was open. The skin cells slowly reproduce and grow back. Then its impossible to tell you were cut.
bone marrow produces red and white blood cells(stem cells in marrow grow and develop into blood)
Well, it depends on what you mean, like they can die of old age, when you die of old age it's because your system starts to shut down, and there aren't anymore blood cells to help you, because when you're younger your blood cells reproduce and grow and grow and grow ! But as you age older, your blood cells start to die can't produce.
it can take anywhere from 3 months to 1 year for eyelashes to grow back
by the way the cells r produced
In the blink of an eye
