A minor ERROR in HUMAN BIOLOGY !

LOCATION :  AP BIOLOGY > HUMAN BIOLOGY > Circulatory and pulmonary systems > RED BLOOD CELL video !

 

In this video, i think there is a minor error. The video relates that the alveoli is connected with bronchioles but this is not true ! Actually the perfect situation is the Alveolur duct is connected to alveoli ! 

 

The correct sequence is :

 

Trachea > Primary Bronchus > Secondary Bronchus > Tertiary Bronchus > Bronchioles > Alveolar duct > Alveolar sac(atrium) > Alveoli
