Question 1

Kidneys

Answer 1

Filter waste products from the bloodstream and convert the filtrate into urine

Question 2

Ureters

Answer 2

Transport urine from kidney to bladder via peristalsis

Question 3

Urinary Bladder

Answer 3

Storage of urine

Question 4

Urethra

Answer 4

Transports urine from bladder to outside of the body

Question 5

Filtration

Answer 5

Within the renal corpuscle, fluid and soulte are pushed from the capillaries into Bowman’s capsule

Question 6

Reabsorption

Answer 6

Selective movement of substances from subules back into blood

Question 7

Secretion

Answer 7

Transfer of substances from the capillaries into the tubule

Question 8

Glomerular Filtration Rate

Answer 8

The amount of filtrate kidneys produce each minute

Question 9

Anti-diuretic Hormone

Answer 9

Controls water reabsorption in distal convoluted tubule and collecting duct. Made by neurons in the hypothalamus and stored in the posterior pituitary, where it is released when plasma osmolarity is too high or when there is a large drop in blood pressure

Question 10

Aquaporin

Answer 10

Water travels through aquaporins passively and aby osmosis

Question 11

Renin

Answer 11

Controls 8% of Na+ reabsorption

Question 12

Granular Cells

Answer 12

Smooth muscle cells in afferent arteriole which release renin

Question 13

Macula Densa Cells

Answer 13

Specialised cells in distal tubule

Question 14

Angiotensinogen

Answer 14

A plasma protein activated to angiotensin I by renin

Question 15

Aldosterone

Answer 15

Released by the adrenal cortex in response to a angiotensin II trigger, to stimulate NA+ reabsorption.

Question 16

ACE

Answer 16

An enzyme which converts angiotensin I to angiotensin II in the lungs
