Igsce biology respiratory system

Nose

Passageway for air

Let’s in oxygen ,let’s out carbon dioxide

Nasal cavity

Filters,moistens and warms the air

Mouth

Passageway for food ,water and air

Pharynx

Common passageway for air, food. And liquids

Larynx

(Voice box) produces sound

Lung

Main organ for gas exchange

Tracheas

(Windpipe) main airway

Epiglottis

Cover larynx while swallowing food or liquids

Bronchi

Branching airways

Bronchi

Branching airways

Alveoli

Air sacs for gas exchange

Diaphragm

Skeletal muscle of respiration

Collated cells

Surface cells within the nose an other parts of the respiratory system .

Sweeps material outwards the system, or towards back of the throat so it’s swallowed and processed

Bronchioles

last branches before the end of the air pathway / airway

Alveoli

End of the airway of the air pathway in lungs

Gas exchange takes place here

Hint looks like grapes

What are found around the alveoli

Blood vessels/ capillaries

What supports the trachea

The cartilage

Goblet cells

Produces mucus which traps dusts , dirt and bacteria to revert entering the lungs

Ciliated cells

Hair like cells that push the mucus back and out the airways
