Question 3

ureter

Answer 3

tube which carries urine from kidney to bladder

Question 4

what is adh

Answer 4

hormone

Question 5

what are the key functions of the urinary system

Answer 5

• filter waste products from blood and expel them from the body as urine
• control water levels of body ( osmoregulation)

Question 6

renal vein

Answer 6

delivers deoxygenated blood from the kidney to the vena cava

Question 7

ADH

Answer 7

anti-diuretic hormone

Question 8

what does ADH make the collecting duct become

Answer 8

more permeable so more water is reabsorbed back into the fluid

Question 9

what does the brain tell the _____to release accroding to ___

Answer 9

• pituitary gland
• ADH
• according to how much is needed in the blood

Question 10

any change in water levels in the blood are detected by the ______ which then sends a signal to the ____

Answer 10

hypothalamus
pituitary gland

Question 11

what produces ADH

Answer 11

pituitary gland

Question 12

if water content is too high …

Answer 12

• The pituitary gland releases less ADH which leads to less water being reabsorbed in the collecting ducts of the kidney by osmosis (the collecting ducts become less permeable to water)
• As a result, the kidneys produce a large volume of dilute urine

Question 13

if water content is too low

Answer 13

• The pituitary gland releases more ADH which leads to more water being reabsorbed in the collecting ducts of the kidney by osmosis (the collecting ducts become more permeable to water)
• As a result, the kidneys produce a small volume of concentrated urine
