Verified step by step guidance

Understand the primary functions of the urinary system: The urinary system is responsible for filtering blood, removing waste products, regulating electrolyte balance, and maintaining fluid balance. It also plays a key role in regulating blood pressure through mechanisms like the renin-angiotensin-aldosterone system (RAAS).

Analyze the options provided: Blood pressure, oxygen transport, digestion of proteins, and body temperature. Consider which of these functions aligns most closely with the urinary system's role.

Eliminate unrelated options: Oxygen transport is primarily managed by the respiratory and circulatory systems, digestion of proteins is a function of the digestive system, and body temperature is regulated by the hypothalamus and skin (thermoregulation).

Focus on blood pressure: The urinary system regulates blood pressure by controlling the volume of blood (via water retention or excretion) and releasing hormones like renin, which influence blood vessel constriction and sodium balance.

Conclude that the correct answer is blood pressure, as it is directly regulated by the urinary system through fluid balance and hormonal mechanisms.
