4 processes of respiration

Pulmonary ventilation
Expiratory respiration
Transport of respiratory gases
Internal respiration

1

Air in/out, gas exchanged in lungs

Pulmonary ventilation

2

Gas exchange between blood & alveoli in lungs

Expiratory respiration

3

Transport of O2 & CO2

Transport of respiratory gases

4

Gas exchange between blood & tissues

Internal respiration

5

3 portions of nasal cavity

Vestibule
Olfactory region
Respiratory region

6

3 types of cells in the olfactory region

Olfactory cells
Supporting cells
Basal cells

7

Conducts air from the nose up to the terminal bronchioles

Conducting system

8

Actual site of gas exchange

Respiratory system

9

Cellular sites of exchange of O2 & CO2 between inspired air & blood, sac like structures that make up most of the lungs

Alveoli

10

5 major cell types in the respiratory epithelium

Ciliated columnar cells
Goblet cells
Brush cells
Small granule cells
Basal cells

11

Most abundant cell in respiratory epithelium with 250-300 cilia on its apical surface

Ciliated columnar cells

12

These cells are numerous in the respiratory epithelium, with basal nuclei & apical domains filled with granules of mucin glycoproteins

Goblet cells

13

Chemosensory receptors resembling gustatory cells, with similar transduction components & synaptic contact with afferent nerve endings on their basal surfaces (columnar cell type)

Brush cells

14

Kulchitsky cells

Small granule cells

15

Mitotically active stem & progenitor cells that give rise to other epithelial cells

Basal cells

16

A specialaized region of the mucous membrane covering the superior conchae at the roof of the nasal cavity

Olfactory epithelium

17

These are the stem cells for the olfactory & supporting cells, replacing the olfactory neurons every 2 to 3 months & support cells less frequently

Basal cells

18

Loss or reduction of the ability to smell

Anosmia or hyposmia

19

The best neurons to be replaced regularly because of regenerative activity of the epithelial stem cells from which they arise

Olfactory neurons

20

Bilateral cavities in the frontal, maxillary, ethmoid, & sphenoid bojes of the skull

Paranasal sinuses

21

An inflammatory process of the sinuses that may persist for long periods of time, mainly because of obstruction or drainage of orifices

Sinusitis

22

An inherited genetic disorder characterized by defective ciliary action

Primary ciliary dyskinesia or Kartagener syndrome

23

Mixture of alveolar fluid & bronchial mucus which help remove particulate matter component from inspired air

Bronchoalveolar fluid

24

Are structures that separate the air in the alveoli from the capillary blood

Blood-air barrier

25

False vocal cords

Vestibular folds

26

True vocal cords

Vocal folds
