A
Regulation of blood glucose levels
B
Production of erythropoietin to stimulate red blood cell production
C

D
Secretion of digestive enzymes
Verified step by step guidance1
Understand the primary function of the kidneys: The kidneys are responsible for filtering blood to remove waste products, excess substances, and toxins, maintaining homeostasis in the body.
Identify the role of a dialysis machine: A dialysis machine acts as an artificial kidney by performing the filtration process, removing waste products from the blood when the kidneys are not functioning properly.
Differentiate between the functions listed: Regulation of blood glucose levels and production of erythropoietin are not functions of a dialysis machine. These are specific functions of the pancreas and kidneys, respectively.
Recognize the correct function: The dialysis machine's main function is to filter blood to remove waste products, similar to the natural filtration process performed by healthy kidneys.
Clarify misconceptions: Secretion of digestive enzymes is a function of the digestive system, not related to the kidneys or dialysis machines.
