Excretion

Question 1

kidney function

Answer 1

removes waste
balances/maintains water and blood pH

Question 2

deamination

Answer 2

removal of amino group in liver

Question 3

deamination byproduct

Answer 3

NH3

Question 4

urea/uric acid

Answer 4

waste product in urine

Question 5

nucleic acids

Answer 5

breaks down into uric acid with breaks down into urine

Question 6

how many litres of water is lost during urination and perspiration

Answer 6

2L

Question 7

formation of urine

Answer 7

1. filteration
2. reabsorbtion
3. secretion

Question 8

filteration

Answer 8

fluid goes from GL to BC
GL is under high pressure
solutes from high to low pressure

Question 9

reabsorbtion

Answer 9

selective transfer of essential solutes and water back to blood

Question 10

where does reabsoptiom occur

Answer 10

proximal tube

Question 11

active transport in reabsorbtion

Answer 11

carrier molecule like N move across cell membrane that line northrop back to blood

Question 12

passive transport in reabsorption

Answer 12

2 osmotic forces are created

Question 13

secretion

Answer 13

movement of water from blood into nephron

Question 14

ADH (Antidiuretic hormone)

Answer 14

increases water reabsorbtion in nephrons = decrease urine concentration = more water conservation in body
