Verified step by step guidance

Understand the primary function of the urinary system: The urinary system is responsible for filtering blood, removing waste products, and regulating blood volume and composition.

Identify the components of the urinary system: The major organs include the kidneys, ureters, bladder, and urethra. The kidneys play a central role in filtering blood and producing urine.

Clarify the processes involved: The kidneys filter waste products like urea, creatinine, and excess ions from the blood, while also maintaining electrolyte balance and blood pressure through mechanisms like the renin-angiotensin system.

Compare the options provided: Exchange of gases between blood and air is a function of the respiratory system, absorption of nutrients from food is a function of the digestive system, and production of hormones for growth is primarily associated with the endocrine system.

Conclude that the correct answer is regulation of blood volume and removal of waste products, as this aligns with the primary role of the urinary system.
