Control Of Water And Ion Content Of The Body
Akopọ
Breathe onto a cold window and a patch of mist appears. That water was inside you a moment earlier, and nothing you decided put it there. Spend an afternoon working in the sun and your shirt dries into a faint pale crust, which is what stays behind when the water in sweat evaporates and the dissolved salts do not. Neither loss asked your permission and neither of them ever stops.
This lesson follows water, dissolved ions and a little waste out of the body by the three routes that carry them: the lungs, the skin and the kidneys. You will learn exactly which substance leaves by which door, why two of those doors cannot be closed however short of water you are, what the small word excess is doing in the phrase excess water is removed via the kidneys, and how to set a day of intake against a day of losses accurately enough to work out a volume nobody measured.
Awọn Afojusun
- Water leaves the body via the lungs when we breathe out and the skin when we sweat. Excess water is removed via the kidneys in the urine.
- Urea and ions are lost via the skin when we sweat. Excess ions are removed via the kidneys in the urine.
