Respiratory system Flashcards
Put in order the most soluble to the least soluble
Oxygen
Carbon Dioxide
Nitrogen
Carbon dioxide
Oxygen
Carbon dioxide
Oxygen + glucose energy + CO2 + water vapour
Respiration
Function of respiration
Inspire oxygen
expire carbon dioxide
Voice production
Temp regulation
acid base balance
Sense of smell
Define EXTERNAL respiration
Gaseous exchange between the air and the blood
Define Internal respiration
Gaseous exchange between the blood and the tissues
Structures involved in upper respiratory
(nose, nasal cavity, sinuses, pharynx and larynx)
Structures involved in lower respiratory tract
trachea, bronchi, bronchioles, lungs and alveoli
Percentage of nitrogenous gasses inspired and expired
Inspired: 79%
Expired: 79%
Percentage of oxygen inspired and expired
Inspired:21%
Expired: 16%
Percentage of carbon dioxide inspired and expired
Inspired: 0.04%
Expired: 4.5%
Structures within the nose
Nasal cavity and turbinate bones
PHARYNX
Cavity at back of mouth leading to the oesophagus and trachea
LARYNX
Between the pharynx and trachea, the voice box
TRACHEA
The windpipe running from the larynx down the neck and into the thorax
BRONCHI
Divisions and branches of the trachea entering the lungs
ALVEOLI
Tiny air filled sacs within the lungs where gaseous exchange occurs
Nose and Nasal Cavity functions
Warming
Filtering
Moistening
What tissue lines the nasal cavity
Ciliated mucous
epithelium
Location, structure and function of Turbinates?
Nasal cavity
scrolled bones
cooling of air?
Tissue covering external Rhinarium
stratified
squamous epidermis
(containing glands)
Alar folds
The scrolls of the external Rhinarium
Philtrum
line down to mouth
What is TRE
typical respiratory epithelium
ciliated pseudo-stratified columnar epithelium with
goblet cells
Where is TRE found in the body
Upper respiratory tract
What are sinuses?
A sinus is an air-filled cavity lying within a bone
location of The Frontal Sinus
Lies within the frontal bone of the skull, above and between the eyes
Location of The Maxillary Sinus
Lies between the maxillary bone and the palatine bone just below each eye
What are the three sections the pharynx is split into?
Nasopharynx (dorsally)
Oropharynx (ventrally)
Laryngopharynx
What splits the pharynx the Nasopharynx and Oropharynx.
The soft palate
Purpose of Eustachian or auditory tubes
Ensure air pressure is equalised to protect the tympanic membrane
The Larynx
framework of cartilage, vocal cords and
muscle that connects the pharynx and trachea
Function of the larynx
ensure that only gases pass down
into the lower respiratory system
