Flashcards in Lecture 1 - Introduction to respiratory anatomy Deck (17):
1

Describe O2 and CO2 transfer in the respiratory system

o2 passes from air to lungs
co2 passes from blood to air

2

Respiratory system is also involved in

speech and smell

3

2 part of the resp system

conducting portion and respiratory portion

4

Conducting portion

nasal cavity to the terminal bronchi

5

Right lung

3 lobes
horizontal fissure - divides superior and middle lobes
oblique fissure - divides superior and inferior lobes

6

Left lung

2 lobes - superior and inferior lobe

7

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

8

What does the respiratory portion comprise of

terminal bronchioles form:
respiratory bronchioles and alveolar sacs

9

The parts of the respiratory system anatomically

Upper and lower respiratory tract

10

Upper respiratory tract

nasal cavity to pharynx
infection - cold

11

Lower respiratory tract

Trachea to bronchi to lungs
lrt - pneumonia

12

functions of the thoracic cage

protection
respiratory movements

13

what does breathing involve

fresh atmospheric air passes to alveoli
stale air leaves alveoli
involves alternate increase and decrease in thoracic volume

14

3 planes of movement of thoracic wall

vertical
antero-posterior
transverse
all 3

15

Main muscle of inspiration

diaphragm

16

Which dome of the diaphragm is higher up

the right dome

17

movements decribed as

pump handle (vertical) and bucket handle (elevation of lateral ribs)
