sensible fluid losses ar those the person is aware of such as through wound drainage, GI tract losses and urination. Insensible fluid losses may occur without the person's awareness. Insensible losses occur daily through the skin and lungs.

Insensible perspiration (losses from skin and lungs)
Insensible fluid loss , is not readily seen or felt fluid, excreted from the body. Insensible fluid loss consists of 1)vaporization from lungs ( exhaled watervapor) and 2) passive diffusion through skin ( also called perspiratio insensibilis = insensible perspiration ). All values below are for adult humans: Vaporization from lungs : average amount 300 ml. , will increase with hard physical work and in dry hot climate. Insensible perspiration : average amount 350 ml. . Other ways of fluid excretion, that are not insensible fluid loss : Urinary production ( of urine ) can be seen : average amount daily 1000 - 1500 ml - will increase if you are overhydrated - and decrease if you are dehydrated. Active sweating from sweat glands can be seen : average amount daily 150 ml. , will increase in case of physical hard work or high temperatures. Fluid lost to the fecal matter in the intestines : average amount daily : 150 ml. , but will increase in case of Diarrhea.
