is a small network of capillaries encased in the upper end of the nephron by a hollow cup shaped structure called Bowman's Capsule
loop of henle
is a section of the nephron tubule in which water is conserved and the volume of urine minimized
bed of capillaries. Supply nephron with o2. reabsorb useful things originally filtered out
made by the break down of amino acids and nucleotides. toxic to mammals. In fish waste primarily
formed naturally in the breakdown of nucleotides.insoluble in water. primary for of waste in birds and reptiles.
creatinine phosphate is a source of rapid ATP production in muscles. by passes cellular respiration
the flow in/out of nephron
renal arteriole, afferent arteriole, glomerulus,efferent arteriole,peritubular capillaries, renal venule
hormones and drugs are actively transported out of blood and into nephron tubule for elimination.This is why drug testing works
bacteria enter the bladder through the urethra and irritate the lining of the bladder and infect the nephrons
genetic, diet, disease, or stress related disorder that increases pressure in the blood vessels.
flow of filtrate through nephron
Bowmans Capsule, proximal tube, loop of henle,distal tubule,collecting duct, papilla, renal pelvis, ureter, bladder,urethra
filters the blood of waste, maintain the blood ph, and regulation of water balance.regulates osmolarity of blood (amount of dissolved solutes)
What remains in the blood
the plasma proteins cells and platelets to large to pass through the capillary walls
bile(dead red blood cells salts and cholestrol. converts to amino acids to other useful compounds into urea
ingredients of urine per 1 liter
95% water, 20 grams urea, 1- 2 gs ammonia, 1-2 gs uric acid, 1-2 gs creatine
how does ADH control the excretory system
controls the amount of h2o in your urine; controls osmolarity of your blood; act on the collecting duct nephron; makes water leave the collecting duct and re enter blood when you are dehydrated
