Renin-Angiotensin-Aldosterone System When blood volume is low, juxtoglomerular cells in kidney secrete the hormone renin Renin triggers the conversion of angiotensin I & II Angiotensin is a vasoconstrictor, causing blood pressure to rise Angiotensin also triggers the release of the hormone aldosterone by the kidney, which causes sodium retention in the distal convoluted tubule Increased sodium causes the blood to retain water, raising blood pressure

Vasopressin/Anti-Diuretic Hormone Hypothalamus detects decline in water content of blood Anterior pituitary gland releases vasopressin (ADH) Vasopressin increases water retention in the collecting ducts of the nephron Vasopressin is a vasoconstrictor, causing elevation of blood pressure Hormone can be turned off by alcohol or caffeine consumption

Blood pH must be maintained between Alkalosis is a blood pH > 7.45 Acidosis is a blood pH < 7.35 Cellular metabolism produces standing acids/H+ donors (carbonic, phosphoric, lactic,fatty) Plasma-Based Buffering Systems (bicarbonate, phosphate, protein) help to temporarility maintain pH levels

Kidneys assist in regulation of pH by excretion of acids into filtrate and reabsorption of bicarbonate ions
