such animals do not undergo a net gain or loss of water
an organism whos body fluids have a solute concentration equal to that of its surroundings, they do not have a net gain or loss of water by osmosis
the use of energy in controlling the loss or gain of water
stored in the urinary bladder
a small and very toxic nitrogeneous waste produced by metabolism
uric acid
an insoluble precipitate of nitrogeneous waste excreted by land snails, insects, birds and some reptiles
fluid extracted by the excretory system from the blood or body cavity, the excretory system produces urine from the filtrate after extracting valuable solutes for it and concentrating it
a duct that conveys urine from the kiddney to the urinary bladder
urinary bladder
the pouch where urine is stored prior to elimination
a duct that conveys urine from the urinary bladder to the outside, in the male it also conveys semen out of the body during ejaculation
renal cortex
the outer portion of the vertebrate kidney
renal medulla
the inner portion of the vertabrate kidney, beneath the renal cortex
the tubular excretory unit and associated blood vessels of the vertabrate kidney; extracts filtrate from the blood and refines it into urine
bowmans capsule
a cup shaped swelling at the recieving end of a nephron in the vertabrate kidney; collects the filtrate from the blood
collecting duct
a tube in the vertebrate kidney tht concentrates urine while conveying it to the renal pelvis
in the vertabrate kidney, the part of a nephron consisting of the capillaries that are surrounded by bowmans capsule; together a glomerulus and bowmans capsule produce the filtrate from the blood
proximal tubule
in the vertebrate kideney, the portion of a nephron immediately downstream from bowmans capsule that conveys and helps refine filtrate
loop of henle
in the vertebrate kidney the portion of a nephron that helps concentrate the filtrate while convey
distal tube
in the vertebrate kidney, the portion of a nephron that helps refine filtrate and empties it into a collecting duct
in the vertebrate kidney, the extraction of water and small solutes, including metabolic wastes fro the blood by nephrons
in the vertabrate kidney, the reclaiming of water and valuable solutes from the filtrate
in the vertabrate kidney, the discharge of waste from the blood into the filtrate from the nephron tubules
the disposal of nitrogen containing metabolic wastes
hepatic portal vessel
a blood vessel that conveys blood from the capillaries surrounding the intestine directly to the liver
