GENERAL HISTOLOGY

Detailed explanation-1: -Human urine is composed primarily of water (95%). The rest is urea (2%), creatinine (0.1%), uric acid (0.03%), chloride, sodium, potassium, sulphate, ammonium, phosphate and other ions and molecules in lesser amounts30 (Table 1).

Detailed explanation-2: -Generally, a high BUN level means your kidneys aren’t working well. But elevated BUN can also be due to: Dehydration, resulting from not drinking enough fluids or for other reasons. Urinary tract obstruction. Congestive heart failure or recent heart attack.

Detailed explanation-3: -An adult human being normally passes about 1.8 litres of urine in 24 hrs. The urine consists of 95% of water, 2.5% of urea and 2.5% other waste products.

Detailed explanation-4: -Urine has large amounts of nitrogen, phosphorus, and potassium. Nitrogen content in urine is high, mostly in urea, which makes up more than 50 percent of the total organic acids. This includes urea from protein metabolism, sodium and potassium both of which come from food.
