✓ Correct answer: C. Filtration of blood and removal of waste Answer: Filtration of blood and removal of waste The primary function of the renal system (kidneys) is to filter the blood and remove waste products, which are excreted as urine. This system helps in maintaining the body's fluid and electrolyte balance, as well as regulating blood pressure. The renal system is not responsible for the regulation of immune responses, secretion of hormones, or production of neurotransmitters.
