Exchange Surfaces

Question 1

Breathing pattern comparison

Answer 1

Deep breaths and breathing rate

Question 2

Why does heart rate increase

Answer 2

Impulses sent along SAN the SAN responds by increasing rate it creates names of excitation

Question 3

Muscle contraction

Answer 3

Increases ventilation of tracheal system

Question 4

Spirometer

Answer 4

Enrich the air with oxygen so blood higher oxygen saturation is maintained

Question 5

Large SA doesn’t hep efficiency

Answer 5

More faster gas exchange

Question 6

Bell jar model

Answer 6

Question 7

Compensation of another organ

Answer 7

Stimulate growth of cell or function

Question 8

Answer 8

Question 9

Answer 9

Question 10

Not diffusion

Answer 10

Absorption of oxygen when oxygen levels are low

Question 11

One cell thick cells

Answer 11

Epithelium

Question 12

How is co2 carried through body

Answer 12

From cells by blood passing out tracheoles

Question 13

Hot gases

Answer 13

Move up by convection as they’re less dense and expand

Question 14

When talking about shape of organisms

Answer 14

It’s their surface area to volume ratio or what’s exposed to heat

Question 15

Answer 15

Question 16

Specialised exchange surfaces

Answer 16

Diffusion distance is long

Question 17

Answer 17

Question 18

Cartilage and elastic fibres

Answer 18

C stops trachea collapsing. E recoil of alveoli

Question 19

Structures G gas exchange

Answer 19

Bronchiole

Question 20

Ventilation problems

Answer 20

Diameter of branchi so harder to exhale so more air remains in lungs

Question 21

Passive

Answer 21

No atp so no muscle contraction

Question 22

Variables

Answer 22

Type or brand. Age. Lifestyle ie diet

Question 23

Answer 23

A is a spiracle and B is a trachea

Question 24

How to observe gills

Answer 24

Remove operculum

Question 25

Tissue in gills

Answer 25

Bone and epithelial

Question 26

Alveoli are

Answer 26

Sacs

Question 27

Alveoli have epithelium

Answer 27

Squamous

Question 28

Smooth music

Answer 28

Constricts bronchiole

Question 29

Oxygen uptake in spirometer

Answer 29

Pick two peaks divide by time. Always compare sample size if valid

Question 30

Soda lime

Answer 30

Removes co2

Question 31

How paralysis of diaphragm could lead to suffocation

Answer 31

No change in thorax volume or pressure

Question 32

Operculum opens and highest rate of oxygen diffusion into blood

Answer 32

First row only has buccal cavity floor lowers Second row is mouth opens operculum opens and highest rate of diffusion

Question 33

Improvements to gill observation

Answer 33

Remove operculumn use pins to hold fish down
