Lecture 1 - Introduction to respiratory anatomy Flashcards
Describe O2 and CO2 transfer in the respiratory system
o2 passes from air to lungs
co2 passes from blood to air
Respiratory system is also involved in
speech and smell
2 part of the resp system
conducting portion and respiratory portion
Conducting portion
nasal cavity to the terminal bronchi
Right lung
3 lobes
horizontal fissure - divides superior and middle lobes
oblique fissure - divides superior and inferior lobes
Left lung
2 lobes - superior and inferior lobe
Medial view of the lung roots
Right Anterior left superior
In the right lung - the vein is anterior to the artery
In the left lung - the vein is superior to the artery
What does the respiratory portion comprise of
terminal bronchioles form:
respiratory bronchioles and alveolar sacs
The parts of the respiratory system anatomically
Upper and lower respiratory tract
Upper respiratory tract
nasal cavity to pharynx
infection - cold
Lower respiratory tract
Trachea to bronchi to lungs
lrt - pneumonia
functions of the thoracic cage
protection
respiratory movements
what does breathing involve
fresh atmospheric air passes to alveoli
stale air leaves alveoli
involves alternate increase and decrease in thoracic volume
3 planes of movement of thoracic wall
vertical
antero-posterior
transverse
all 3
Main muscle of inspiration
diaphragm
