Human physiology is the science of the mechanical, physical, and biochemical functions of normal humans or human tissues or organs. ... Renal physiology is the study of the physiology of the kidneys. ... Acid-base physiology is the study of the acids, bases and their reactions in the body. ... In chemistry, alchemy and water treatment, filtration is the process of using a filter to mechanically separate a mixture. ... Ultrafiltration (UF) is a variety of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. ... Countercurrent exchange is a mechanism used to transfer some component of a fluid from one flowing current of fluid to another across a permeable barrier between them. ...

Hormones affecting filtration:Antidiuretic hormone (ADH) - Aldosterone - Atrial natriuretic peptide Arginine vasopressin (AVP), also known as argipressin or antidiuretic hormone (ADH), is a human hormone that is mainly released when the body is low on water; it causes the kidneys to conserve water by concentrating the urine and reducing urine volume. ... Aldosterone is a steroid hormone synthesized from cholesterol by the enzyme aldosterone synthase. ... Atrial natriuretic factor (ANF), atrial natriuretic peptide (ANP) or atriopeptin, is a polypeptide hormone involved in the homeostatic control of body water and sodium. ...

Endocrine: Renin - Erythropoietin (EPO) - Calcitriol (Active vitamin D) - Prostaglandins The endocrine system is a control system of ductless endocrine glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distant organs. ... Renin, also known as angiotensinogenase, is a circulating enzyme (EC 3. ... Erythropoietin (IPA pronunciation: , alternative pronunciations: ) or EPO is a glycoprotein hormone that is a cytokine for erythrocyte (red blood cell) precursors in the bone marrow. ... Vitamin D is a fat soluble vitamin that contributes to the maintenance of normal levels of calcium and phosphorus in the bloodstream. ... Chemical structure of prostaglandin E1 (PGE1). ...

In nephrology, dialysis adequacy is the measurement of renal dialysis for the purpose of determining dialysis treatment regime and to better understand the pathophysiology of renal dialysis. ... Glomerular filtration rate (GFR) is the volume of fluid filtered from the renal glomerular capillaries into Bowmans capsule per unit time. ... Creatinine clearance is a method that estimates the glomerular filtration rate (GFR) of the kidneys. ... The renal clearance ratio is found with the following equation: X is the analyte substance Cx is the renal plasma clearance of X Cin is the renal plasma clearance of inulin. ... The urea reduction ratio (URR), is a dimensionless number used to quantify hemodialysis treatment adequacy. ... Kt/V - a dimensionless number used to quantify hemodialysis and peritoneal dialysis treatment adequacy. ... Standardized Kt/V, also std Kt/V, is a way of measuring (renal) dialysis adequacy. ... Hemodialysis product (HDP) - is a number used to quantify hemodialysis and peritoneal dialysis treatment adequacy. ...
