Hello, your question is missing its options so I went online to find them.
Here they are:
All of the following processes are functions of the urinary system EXCEPT __________.
A. elimination of urine .
B. excretion of excess ions such as sodium or potassium .
C. regulation of blood volume .
D. production of urea.
Answer:
The correct answer is: D. production of urea.
Step-by-step explanation:
The urinary system is the system responsible for the filtration of the blood and the elimination of wastes. When blood reaches the nephrons (the structural unit of the kidneys), it is filtered in order to eliminate anything that is not of use. Once filtered, the components that travel through the tubules in the nephrons can be reabsorbed into the bloodstream or have the addition of products that are secreted from the blood and into the tubules for them to be excreted.
The production and elimination of urine are fundamental for the correct functioning of the body, as it regulates the concentration of ions and water, which deeply impacts in the volume and osmolarity of the extracellular fluids such as blood plasma and interstitial fluid. This way, it can be said that the urinary system is responsible for A) the elimination of urine, B) the excretion of excess ions, and c) the regulation of blood volume.
Urea, however, although it has an important role in the reabsorption of water and ions in the nephrons, it is not produced in the urinary system. Urea is a carrier of waste nitrogen.
