70%
What 3 factors are unique to the glomerular capillaries?
High BP, No Oxygen Exchange, Large Cell Gaps
What happens to the efferent arteriole after it leaves the glomerulus?
Wraps around the rest of the nephron, becomes peritubular capillary
What is recovered by reabsorption in the nephron?
Water, Glucose
What is secreted by the nephron in the urine?
Potassium, Ammonia, Medications
Where is ADH produced?
Pituitary Gland
What hormone promotes water reabsorption?
ADH
Where is aldosterone produced?
Adrenals
(water follows salt)
Aldosterone
What are the three stages of urine production?
Filtration, Reabsorption, Secretion
Where does the urine production stage “filtration” happen?
Glomerulus
Where does the urine production stage “reabsorption” happen?
Loop of Henle
Where does the urine production stage “secretion” happen?
Distal Convoluted Tubule
What three nephron structures are found in the cortex of the kidney?
Bowman’s capsule, PCT, DCT
What nephron structure can be found in the medulla part of the kidney?
