Question

a 29 - year - old female presents with low blood urea nitrogen. what organ is most likely involved?

Explanation:

Blood urea nitrogen (BUN) is a measure of the amount of urea nitrogen in the blood. Urea is produced in the liver as a by - product of protein metabolism. The kidneys are responsible for filtering urea from the blood and excreting it in the urine. However, low BUN levels can be associated with liver dysfunction. In liver failure or severe liver disease, the liver may not be able to produce enough urea from ammonia (a by - product of protein metabolism). This leads to lower levels of urea nitrogen in the blood.

Answer:

The liver.
