Reproduction
Controlling their internal environment

Question 2

Epidermis

Answer 2

Hair

Pore

Question 3

Dermis

Answer 3

Hair erector muscle
Oil gland
Sweat gland
Pain receptor
Temperature receptor
Pressure receptor
Capillary loop

Question 4

Hypodermis

Answer 4

Fat layer

Question 5

Body temperature

Answer 5

37*C for the enzymes to work properly

Question 6

How is body temperature kept constant

Answer 6

Sweat evaporates front he surface of your skin

You flush and lose heat by radiation through your skin

Question 7

ADH and osmoregulation

Answer 7

Solute of concentration up/down
Detected in hypothalamus
Pituitary gland releases more ADH
ADH travels to kidney tubules
More/less water reabsorbed into blood
Small/large amount of of concentrated wine formed
Blood concentration of so lutes restored to normal
ADH production falls to normal/arises again

Question 8

Kidneys

Answer 8

Excretes urea

Urine, sweating, breathing out, faeces remove too much water

Question 9

Kidney functions

Answer 9

Balances the amount of water left in the blood
You take in mineral ions with your food these are lost in sweat
Removed in urine

Question 10

Osmoregulation

Answer 10

The balance of water and mineral ions

Question 11

Answer 11

Keeping conditions inside the body constant

Changing them when the environment changes

Question 12

How is homeostasis made possible

Answer 12

By excretion

Question 13

Carbon dioxide produced

Answer 13

During respiration

Question 14

Urea produced

Answer 14

When amino acids are broken down

Question 15

Why must salt be balanced with

Answer 15

Must be balanced with water

So cells don’t have problems with Osmosis

Question 16

What do kidneys control

Answer 16

Filter the blood

Control the amount of water/ions taken in

Question 17

Core body temperature controlled by

Answer 17

The thermoregulatory centre in the brain

Question 18

Diabetes

Answer 18

When the body doesn’t produce ip enough insulin to keep the glucose level constant

Question 19

Problems of glucose…causing diabetes

Answer 19

Blood sugar may rise to fatally high levels when cells are starved of glucose for respiration

Question 20

When can sugar be excreted

Answer 20

During urination

Question 21

How can diabetes be treated

Answer 21

By injecting insulin before meal times

Question 22

Glycogen and insulin

Answer 22

Keep glucose at a 4-6 mol/1 concentration for cell respiration

Question 23

Pancreas (insulin, glycogen)

Answer 23

Pancreas monitors blood sugar level

1) Decrease in blood sugar level 2)rise in blood sugar level
1) Glycogen released 2)insulin released
1) Glycogen to glucose 2)glucose to glycogen
