Role of the nasal conchae?
To Allow diffusion
To humidify, warm and slow down the air inspirated
To Expel carbon dioxide
Thromboxane A2
What do goblet cells secrete?
Dendrites
Mucous
Hemoglobin
Alveoli
What do type II Alveoli do?
Very thin layer of squamous epithelial cell, makes 97% of alveolar surface area, highly permeable
Secrete surfactant, detergent like substance composed of phospholipids and proteins that reduces surface tension
Secrete cilia
Secrete Goblet cells
What is Boyles Law?
If volume is higher pressure is higher.
The volume of a gas and pressure are inversely proportional at a given temperature
Propulsion of foreign bodies out of the lung
Vasoconstricts when foreign bodies arrive.
Haldane effect describes how oxygen concentrations determine hemoglobin's affinity for carbon dioxide.
Bohr effect describes how carbon dioxide and H+ affect hemoglobin affinity for oxygen.

pH Normal value 7.35 – 7.45
PaO2 Normal value 35 – 45 mmHG
HCO3 - Normal value 22 – 26 mmol/L
BE Normal value +/- 2 mmol/
PaCO2 Normal value 80 – 100 mmHg
Which one of these statements are correct?
Carbon dioxide is transported in the blood in 3 forms:
20% dissolved in plasma
7-10% bound to globin of hemoglobin
70% transported as bicarbonate ions in plasma
What atom binds O2 to heme in hemoglobin
H+
Bicarbonate
Iron
Thromboxane A2
Which one of these statements are incorrect?
Tidal volume (TV), (6mls per kg), is the amount of air inspired during normal, relaxed breathing.
Inspiratory reserve volume (IRV), about 3,100 mL, is the additional air that can be forcibly inhaled after the inspiration of a normal tidal volume.
Expiratory reserve volume (ERV), about 1,200 mL, is the additional air that can be forcibly exhaled after the expiration of a normal tidal volume.
Residual volume (RV), about 1,200 mL, is the volume of air still remaining in the lungs after the expiratory reserve volume is exhaled.
Total lung capacity (TLC), about 4,800 mL, is the total amount of air that can be expired after fully inhaling TV + IRV + ERV. The value varies according to age and body size.

0.5 cell
1 cell
2 cell
3 cell

Anteriorly and medially
posterior and anterior
Up and outward
