Explain the production of urine.
Answers
Answer:
The nephrons of the kidneys process blood and create urine through a process of filtration, reabsorption, and secretion. Urine is about 95% water and 5% waste products. Nitrogenous wastes excreted in urine include urea, creatinine, ammonia, and uric acid.
Explanation:
There are four basic processes in the formation of urine starting with plasma.
Filtration.
Reabsorption.
Regulated reabsorption, in which hormones control the rate of transport of sodium and water depending on systemic conditions, takes place in the distal tubule and collecting duct.
Secretion.
Excretion.
