Urine is produced by filtration of the blood by the kidneys. Waste products urea, creatinine, excess electrolytes are filtered in the kidney and collect in the pelvis from which it trickles down the ureter, two tubes which open in the bladder. The bladder gradually distends and once full, it gives the urge to micturate and you pass out the urine.

Additionally, water also cycles through sheep as they excrete urine and feces, releasing water back into the environment.
The main nitrogenous waste expelled in urine is urea, which is produced in the liver through the urea cycle. This process converts ammonia, a toxic byproduct of protein metabolism, into urea, which is less harmful and can be easily excreted by the kidneys. Urea is then filtered from the blood and eliminated from the body in urine.
Menstruation can potentially affect urine ketone test results, although the impact is generally minimal. Hormonal fluctuations during the menstrual cycle may influence metabolism and hydration levels, which can, in turn, affect ketone production and excretion. Additionally, the presence of menstrual blood in the urine sample could lead to contamination, potentially skewing results. If accurate ketone measurements are needed, it's best to test at a consistent time in relation to the menstrual cycle.
