Question 1

What is the alvioli surrounded by

Answer 1

Capillaries

To allow exchange of oxygen and co2

Question 2

Another name for the windpipe

Answer 2

Trachea

Question 3

The upper part of the trachea

Answer 3

Larynx

Contains vocal cords

Question 4

What is the epiglottis

Answer 4

Anflap which opens and closes as we swallow

Question 5

The trachea branches into two tubes called the

Answer 5

Bronchii

Leading to rather lung

Question 6

The bronchii split into

Answer 6

Bronchioles

Question 7

Cells found in the tubes

Answer 7

Glandular- produces mucus to trap bacteria from entering the lungs
Cilia- small hairs which brush mucus waking with the bacteria back to the theorist to be swallowed

Question 8

What does smoking do

Answer 8

Damages the cilia

And therefore the lungs become dirty due to not removing the mucus and bacteria cough to remove dirt

Question 9

The lung cavity is called a

Answer 9

Thorax

Question 10

What surround each lung

Answer 10

Plural membrane

Double layer with plural fluid in the cavity between

Question 11

During inspiration the lungs are stretched causing the alvioli to

Answer 11

Open and inflate with air

Question 12

Wha muscles are used to force the rib cage down with greater force

Answer 12

Internal intercostal

Question 13

Muscles used during inspiration

Answer 13

Diaphragm

External intercostale

Question 14

What happens if the plural membrane is punctured

Answer 14

The lung on that side will not inflate

Reduced oxygen inhailed

Question 15

Alveoli are the site of

Answer 15

Gaseous exchange

Question 16

Adaptations of alveoli to increase gaseous exchange

Answer 16

Vast air sacs to increase surface area and therefore more exchange of nurturers
Thin walls so minimal distance for the gases to pass through
Inner wall is coated in water to allow oxygen to dissolve before travelling through walls

Question 17

Where does cellular respiration occur

Answer 17

Cytoplasm and mitochondria

Question 18

Food supplies us with what energy

Answer 18

Glucose

Question 19

What happens when the glucose is broken down

Answer 19

Water and co2 relaxed

The energy that was holding the molecule together is also released

Question 20

ATP

Answer 20

Energy got by the breakdown of glucose from ADP

Question 21

What happens during glycolysis

Answer 21

Glucose into pyruvic acid and energy in the cytoplasm

Relaxing ATP

Question 22

Kreb cycle

Answer 22

In the mitochondria

More ATP is generated

Question 23

Stage 3

Electron transport chain

Answer 23

In the walls on the mitochondria
Needs oxygen
Aerobic respiration
Co2 by product

Question 24

Anaerobic respiration

Answer 24

Pyruvic acid is converted to lactic acid
No oxygen required
Can cause oxygen dept

Question 25

Lactic acidosis causes

Answer 25

Fatigue
Position in muscle
Denatures the enzymes in the muscles by changing the pH meaning ATP can not be produced

Question 26

What causes asthma

Answer 26

Inflamed bronchii

Increased mucus production

Question 27

Why does an asthma attack cause

Answer 27

Reduced airbreachingg lungs

Lips and finger tips go blue

Smoking
Cilia paralyse the cleaning part of lungs
Causing a build up on mucus in the lungs
Increased chance of infection

Question 30

What does the reliever inhaler do

Answer 30

Dilated the bronchioles during an attack

Reduced symptoms

Question 31

Brown inhaler

Answer 31

Preventer
Stops attacks occurring
Reduced sensitively of bronchii
