Control of sodium balance

Main mechanisms

• Aldosterone (most important)
• Atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP)
• ADH (in AV6, but not WG21)
• Angiotensin
• Renal nerve stimulation

Other factors not directly involved in renal function

Factors that increase Na+ resorption

• Cortisol
• Oestrogen
• Growth hormone
• Thyroid hormone
• Insulin

Factors that decrease Na+ resorption

• Glucagon
• Progesterone
• Parathyroid hormone
