Terms | Definitions |
|---|---|
 osmoconformers | such animals do not undergo a net gain or loss of water |
| osmoconformers | 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 |
| osmoregulators | the use of energy in controlling the loss or gain of water |
| urine | stored in the urinary bladder |
| ammonia | 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 |
| filtrate | 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 |
| ureter | a duct that conveys urine from the kiddney to the urinary bladder |
| urinary bladder | the pouch where urine is stored prior to elimination |
| urethra | 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 |
| nephrons | 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 |
| glomerulus | 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 |
| filtration | in the vertebrate kidney, the extraction of water and small solutes, including metabolic wastes fro the blood by nephrons |
| reabsorption | in the vertabrate kidney, the reclaiming of water and valuable solutes from the filtrate |
| secretion | in the vertabrate kidney, the discharge of waste from the blood into the filtrate from the nephron tubules |
| excretion | 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 |
