T/F The kidneys produce and release calcitrol & erythropoietin, regulate blood composition & PH, blood volume & pressure & maintenance of blood osmolarity
True

kidneys
Is glucose a waste product secreted by the kidneys?
NO
The ______________ are retroperitoneal and are attached to the posterior abdominal wall

The blood vessels that supply the kidneys are the __________ ___________, receive 20-25% of resting cardiac output via right and left _______ __________
renal arteries
T/F Nephrons are the functional units of the kidneys
True
Most of the nephrons are located entirely in the _____________________
Parenchyma
There are about a _________________ nephrons in each kidney
million
The order in which a ___________ of _________ would normally pass thru nephrons is 1. glomerulus, 2. glomerular capsule, 3. prox convoluted tubule, 4, descending loop of henle, 5. ascending loop of henle, 6. distal convoluted tubule, 7. collecting duct & last papillary duct
molecule of water
T/F Loss of 10% of a persons kidney function may not result in clinically observable effects
True
T/F As a person grown, the # of nephrons in their kidney changes
False - # of nephrons stays constant
T/F If one kidney is removed, the other nephrons in the other kidney will hypertrophy
True
Which of these will not cross the filtration membrane? - Small proteins, water, platelets, ions or monosacharides
platelets
A patient has both systemic lupus erythematosus, which has damaged her liver, and insulin-dependent diabetes mellitus, which has damaged her kidneys. As the diseases have progressed the edema she experiences has worsened. Why?
Liver damage prevents her from making sufficient plasma proteins, & Kidney damage allows some of her plasma proteins to be excreted, both lowering the BCOP
