What is urine and what is it made of?

Urine is made up of range of organic compounds such as proteins and hormones, inorganic salts and numerous metabolites.  These by-products are often rich in nitrogen and need to be removed from the blood stream through urination.  The pH level of urine is typically around (pH7) but varies depending on diet, hydration levels and physical fitness.  The color of urine is also determined by these factors, with dark-yellow factors, with dark-yellow urine indicating dehydration and greenish urine indicating of excessive asparagus consumption.
