Our liver converts ammonia into urea. This urea is excreted out in the urine.
Fatty acids are not excreted in the urine because only water soluble substances can be processed into urine, and fatty acids are lipid soluble, not water soluble.
Plasma proteins and red blood cells are not excreted in urine because they remain in the blood when it is filtered through the kidneys and into the ureters. They are too big to be filtered. Most other substances present in blood are also present in urine since the kidneys filter out poisonous substances as well as substances that are present in excess such as salt and water.
The liquids in which the urea is excreted are: Urine and sweat
