Chapter 48.5, Problem 10LO
Summary Introduction
To describe: Regulation of fluid and electrolyte balance by antidiuretic hormone (ADH), renin-angiotensin-aldosterone system, and atrial natriuretic peptide (ANP).
Introduction: The kidney is an important organ of the excretory system, and nephron is the basic structural unit of kidney. The main function of nephron is ultrafiltration. It removes waste products, ions, and excess water from the blood, and returns the required molecules back to the blood. The glomerular filtration rate (GFR) refers to the rate of flow of filtered fluid through the kidney.
