Respiratory System Anatomy Flashcards
What are the requirements to breath?
An open away
Effective muscles of respiration
A non-toxic atmosphere
Stable chest wall
Ability of the lungs to expand and contract
Free passage of gas from the alveoli and blood
Good circulation
Percentage of oxygen inspired
21%
Percentage of oxygen expired
16%
percentage of c02 inspired
0.04%
percentage of co2 expired
4%
Pulmonary ventilation is?
movement of air in and out of the lungs
External respiration is?
movement of oxygen from the lungs into the blood stream and co2 from the blood stream into the lungs
internal respiration is?
movement of oxygen from the bloodstream into the cells and tissues and co2 from the cells and tissues into the bloodstream
upper airway is?
nose to larynx
lower airway is?
trachea to alveoli
list the anatomy of the nasal cavity
nasal septum,
vestibule,
nasal conchae (turbulent air)
olfactory region
anatomy of the pharynx (in order)
nasopharynx,
oropharynx
Laryngopharnyx
Lower airway anatomy (in order)
Trachea,
carina,
left and right bronchus,
secondary bronchi,
tertiary bronchi,
Bronchioles,
alveoli.
how many lobes in each lung (right/left)
3 lobes in the right
2 lobes in the left
the entry point of the lungs for blood vessels, bronchi, lymph vessels, nerves is called?
The Hilum
the 2 layers of serous membrane are called?
Visceral and Parietal layer
What is in between the visceral and parietal layer?
pleural cavity
how many alveoli per lung?
150 million
How many intercostal spaces and muscles are they?
11 pairs of intercostal muscles, 12 spaces
name the 3 accessory muscles used in respiration
sternocleidomastoid, scalenes and pectoralis minor/major
what is the main muscle used in respiration?
the diaphragm
what is anatomical dead space and the volume?
the residual volume which remains in the air passage but isn’t involved in alveoli exchange. 150mls
what is tidal volume and the volume of this?
the amount of air that passes through and out the lung during quiet breathing. 500mls
