Vigorous physical activity triggers a rapid and coordinated release of the hormones vasopressin and aldosterone and the enzyme renin to minimize sodium and water loss through the kidneys.

Question

Quizplus · Accepted Answer

During vigorous physical activity, the body aims to maintain fluid and electrolyte balance. Vasopressin (antidiuretic hormone) and aldosterone work to conserve water and sodium, respectively, while renin, part of the renin-angiotensin-aldosterone system, helps regulate blood pressure and fluid balance. These mechanisms are activated to minimize sodium and water loss through the kidneys, ensuring hydration and electrolyte levels are maintained during intense exercise.
