I heard that the blood in our body is new every 5 years for females and every 3 years for a man.
I wanted to know if someone can tell me if it's true or not, and give me some more information about that processs in our body.
what do you mean by new blood? Exchanged cells (erytrocytes per 3 months) or exchanged volume or what?
With some probability, there could be some water molecule originating from your mother's body, which is still circulating in your body, just because it was "lucky"
Cis or trans? That's what matters.
I mean that(from what that i heard) that in a mans body, every 3 years, all the blood in his body is new and fresh. for a woman every 5 years.
i dont know anything about blood, biology etc etc. and i would love to get a basic explanation about it.
It's an average, someone trying to decide how quickly blood elements wear out and get replaced.
It's kind of like saying, in a school, the whole population is new every so-many years, trying to factor in entry and graduation and maybe employee turnover. It doesn't imply that on one day after a set time, everything gets replaced.
Can you please point on stuff that can make this process happen faster or slower?
Like having a serious injury lets say, or donating blood?
Are stuff like height and weight can change the time of the process?
Would be happy to get more information!
what I know is our body generate new blood cell in months (not years, as I remember).
I guess this is what you mean. And yes, like darby said that its not a one-day process, every day, some of your blood cell are dead and got degrade, and you got new blood cell as replacement. Our faeces and urine got coloured from blood cell degradation product. So if your faeces (at least) got yellowish color, then blood cell turnover is still happening in your body.
Red blood cell is made at your spine and kidney and is affected by som hormones like erythropoeitin. Therefore, condition affecting kidney such as CRD can affect your blood cell production thus emerge the symptoms of anemia.
Hope this help (and correct), perhaps, others have their correction on my answer
