Answer 1

Anabolic steroid

Question 2

Masking agent

Answer 2

Removal of drugs.

Question 3

Substance measured for kidney failure

Answer 3

Creatinine

Question 4

ADH

Answer 4

Made in hypothalamus
Released by posterior pituitary gland
Carried in vesicles
By exocytosis
Osmoreceptors detect change in w/p of blood
ADH binds to target cells on collecting duct
2nd Messenger

Question 5

Answer 5

Damage to nephron

Question 6

In a liver lobule, how can you identify structures

Answer 6

Artery will have a narrower lumen and be smaller
Hepatic portal vein is next to hepatic artery and branched
Central vein is large empty space in middle
Portal vein is large and oval like at the edge

Question 7

Peritoneal Dialysis

Answer 7

Peritoneal catheter surgically placed in the abdomen

Question 8

What property of hCG allows it to be detected

Answer 8

Mass of less than 69k

Question 9

Control during dialysis

Answer 9

Dialysis tubing length. Initial glucose levels. Brand of dialysis

Question 10

Pct vs DCT

Answer 10

Both use active transport and selective reabsorption

DCT uses calcium and only reabsorbs ions

Question 11

Why can’t something undergo mitosis

Answer 11

Specialised or always in G0
Asymmetrical shape

Question 12

Answer 14

Mention ADH

Question 15

How is ADH neuronal and hormonal

Answer 15

H: osmoreceptors negative feedback and water potential changes

N: ADH from pituitary aldestorare from adrenal cortex, camp

Question 16

Answer 16

Living cells

Question 17

Veins are

Answer 17

Closer to surface than arteries

Question 18

Facilitated diffusion as it requires…

Answer 18

Protein channels to cross membrane

Question 19

Why and how do we regulate catalase

Answer 19

Why: hydrogen peroxide is a lot and has high turnover so lots of oxygen vigorously
How : isolation of catalase in peroxisome and is released in small quantities so cells can limit catalase expression

Question 20

Thin cells so..

Answer 20

Short diffusion distance

Question 21

Whys peritoneum differ from A arficialmembrare

Answer 21

Performs activetransport

Question 22

Kidneys job that requires hypertonic solution

Answer 22

Remove excess water from blood dialysis is counter current

Question 23

Longer loop of Henley

Answer 23

More ions pumped out ascending limb so greater water potential gradient so more water reabsorbed for longer time

Question 24

Basement membrane prevents proteins

Answer 24

From reaching bowman’s capsule
