Respiratory structures with their description
Intercostal muscles
The intercostal muscles are mainly involved in the mechanical aspect of breathing
These muscles help expand and shrink the size of the chest cavity to facilitate breathing
Intercostal muscles are several groups of muscles that run between the ribs, and help form and move the chest wall
Pleural membrane
The pleural membranes cover the outside of the lungs and line the inside of the chest wall
Diaphragm
A dome-shaped muscular partition separating the thorax from the abdomen in mammals
It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs
Alveoli
A tiny cavity or air sacs of the lungs which allow for rapid gaseous exchange. They are moist, thin walled with an excellent blood supply and elastic fibres to withstand pressure changes
Rib
One of a series of slender curved bones articulated in pairs to the spine (twelve pairs in humans), protecting the thoracic cavity and its organs
Larynx
Contains the muscles and ligaments of the vocal cords
Bronchus
A branch of the trachea
Has a smaller diameter than the trachea leading into each lung
Trachea
Tube leading from the pharynx (throat) to the lungs
Supported by strong sections of C shaped cartilage to hold it open during the pressure changes of inspiration and expiration
Pharynx
Passage connecting the nose and mouth to the oesophagus and trachea
Epiglottis
A flap of cartilage behind the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe
Nasal cavity
Air passes through into and out of the lungs
Lined with tiny nasal hairs to trap dust which protects the delicate lungs
Bronchioles
Has incomplete rings of cartilage to hold them open
Has muscular walls that allow them to constrict or dilate to vary the amount of air the enters or leaves the lungs
Contains mucus (traps dust and pathogens) producing goblet cells
Contains ciliated epithelial cells to remove the mucus
A branch of the bronchus
Has a smaller diameter than the bronchus
