Key Points. 1  The majority of fluid output occurs from urination. Some fluid is lost through perspiration (part of the body's temperature control mechanism) and as water vapor in expired air. 2  The body's homeostatic control mechanisms ensure that a balance between fluid gain and fluid loss is maintained.
Urine is the nitrogenous liquid form of waste that is excreted from the body with the help of kidneys through the process of urination. Filtrate is the liquid that is formed in the kidneys while urine formation is taking place. Difference in composition.Water is the major component of urine, forming about 95% of it while the remaining part is formed by other organic and inroganic constituents.fter leaving the Bowmanâs capsule the filtrate goes into the renal tubules where 99% of water, all of glucose and amino acids, most of the Na and Cl ions are reabsorbed back into the blood. As the fluid passes further, more constituents are reabsorbed and finally, urine is formed which is excreted from the body.
