    Does human body organ has any mechanism or function requires the concept of acids or bases? I mean is there any part of human body needs acids or bases to operate? Or you can give me some website to look up by myself that will also be fine.

    Don’t tell me it’s impossible, even if it is. I’m writing a fiction story and I need to know how the human body can be altered to survive underwater.

    I am writing a paper on the affects of iron in the human body and i cant seem to find any definitive information about the difference of fe2+ and fe3+ when it comes to human health.
    I know the body oxidizes fe2+ to fe3+ and fe3+ cannot carry oxygen, but how does that relate to our health?

    With regards to the infamous Periodic Table of Elements (that we all know from high school chemistry class) – what type of molecules and atoms is the human body made up of?

    I know our bodies are mainly composed of water, so that would by Hydrogen and Oxygen molecules. But what else?

    I know that it’s possible to survive in a hard vacuum, disregarding the lack of oxygen; but how long would it be before the temperature of the human body reaches freezing, taking into account that heat loss will be fairly slow without a medium to transmit heat away?

    Thanks

    How much oxygen do the red blood cells in a human body carry? E.g. for an average person of weight 80kg.

    ( I presume it’s not the same as the total carrying capacity of all the red blood cells in a body since something like half of the blood will be carrying carbon dioxide? )

    Thanks

    It’s pretty much known to everybody that the oxygen we breath is O2, Less common knowledge is that Ozone is O3, and highly toxic, but what about O? It doesn’t occur naturally, but that doesn’t necessarily mean it can’t exist, so what effect does it have on a human body?

    Hi Everyone

    I would like to ask you what would happen to oxygen when it goes into our human body system.

    Why do we need to breathe?

    Thank you
    Thank you. That was helpful.
