These hormones include aldosterone (which controls sodium); atrial natriuetic peptide or ANP which traps sodium in the nephron so more urine is produced; anti-diuretic hormone/vasopressin, that helps to conserve water; and the renin-angiotensin-aldosterone system, that balances blood volume and blood pressure to ensure
