list the nine functions of the kidneys
• Regulation of body fluid osmolality and electrolyte concentrations• Regulation of arterial blood pressure• Regulation of acid-base balance• Regulation of erythrocyte production• Regulation of 1, 25-dihydroxy vitamin D3 (Calcitriol) production• Synthesize glucose from AA's (Gluconeogenesis)• Production of hormones/-like substances (Somatomidin and prostaglandins)• Excretion of metabolic waste products and foreign chemicals

Glomerular Filtration Rate
125 ml/min
Reabsorption rate (back into circulation )
124 ml/min
Urinary excretion rate
1 mL/min
How does the kidney handle creatinine ?
filtered only rate of filtration = rate of excretion 100% found in urine
How does the kidney handle electrolytes ?
filtered partially reabsorbed
How does the kidney handle glucose ?
filtered and completely reabsorbed
How does the kidney handle acid and bases ?
filtered and excreted
