The urinary system function is to remove waste from the blood and transport it outside the body.

• A. Remove waste from blood and transport outside
• B. Filter lymph
• C. Produce red blood cells
• D. Secrete hormones

Answer: (A)

The main idea is what the urinary system does with waste. Its primary role is to filter waste from the blood and remove it from the body as urine. The kidneys pull waste products like urea, creatinine, and excess ions from the bloodstream, urine forms and travels down the ureters to the bladder, and then exits through the urethra. This process also helps regulate fluid balance, electrolytes, and pH, supporting overall homeostasis. Filtering lymph belongs to the lymphatic system, producing red blood cells occurs in bone marrow, and secreting hormones is a function of endocrine glands. These are different systems, so they don’t describe the urinary system’s main job.
