Study Notes
Kidneys and Nephrons
- Kidneys are composed of approximately 1 million nephrons, the major functional unit.
- A nephron consists of a glomerulus and renal tubules.
Glomerulus
- Filters 120 ml/min, or one-fifth (1/5) of renal plasma.
- A coil of capillary vessels.
Renal Tubules
- Proximal tubule:
- Reabsorbs water, sodium, chloride, bicarbonate, potassium, calcium, amino acids, phosphates, protein, and glucose.
- Glucose is a threshold substance with a normal range of 160-180 mg/dl.
- Descending Loop of Henle:
- Reabsorbs water.
- Ascending Loop of Henle:
- Reabsorbs sodium, chloride, calcium, and magnesium solutes.
- Distal and Collecting tubule:
- Reabsorbs sodium.
- Secretes potassium through K ion exchange for Na.
Urine Output Terms
- Normal urine output: average of 1200-1500 ml/day.
- Polyuria:
- >2500 ml/day.
- Causes: Diabetes Mellitus, Diabetes Insipidus, Diuretics, Caffeine, and alcohol intake (DDD-CA).
- Oliguria:
- <400 ml/day.
