Explratio is intake of air into lungs T/F

Inspiration Is decrease in volume of thoracic cavity T/F

In Inspiration Relaxation of external intercostal muscles ( muscles present between ribs ) and contraction of internal intercostal muscles occur . T/F

The typical value of residual volume is

a ) 500ml
b ) 3000 ml
c ) 1200 ml

The Po2 in alveoli equals to
----
a ) 160 mmhg
b ) 100 mmhg
c ) 105 mmhg

بعد؟؟

The Po2 of blood in the pulmonary veins and systemic arteries is about 5 mmHg more than that in average alveolar T/F

Decrease in ventilation lead to
a ) Increase in alveolar Po2
b ) Decrease in alveolar Po2
c ) Decrease in alveolar Pco2
