Question

select all that apply
which of the following are functions of the kidney?

□ maintain homeostasis
□ produce insulin
□ filter blood to eliminate waste
□ secrete renin

Explanation:

• Maintain homeostasis: Kidneys regulate blood pressure, electrolyte balance, and fluid volume, all crucial for homeostasis.
• Produce insulin: Insulin is produced by the pancreas, not the kidneys, so this is incorrect.
• Filter blood to eliminate waste: Kidneys filter blood, removing waste products (like urea) and excess substances to form urine.
• Secrete renin: Kidneys secrete renin, an enzyme that helps regulate blood pressure and fluid balance.

Answer:

• Maintain homeostasis
• Filter blood to eliminate waste
• Secrete renin
