All of the air passes through the respiratory zone before being exhaled 10% (100mi/1L) 30% (150ml/500ml) Save All Answers Save and SubmitExplanation / Answer
Anatomical dead space include space with in trachea and primary bronchi. Let me give you an idea of dead space so that you can visualise this. When air travels through the nasal tract to lungs via nose, trachea and bronchi, no gaseous exchange occurs here. The exchange occurs in lung alveoli. This route is just for travelling purpose. It does not contribute to gaseous exchange between body and environment. So it is called dead space. trachea and primary bronchi do not take part in gaseous exchange.
In normal resting breathe, an individual would take in about 1/2 lit. Or 500 ml of air.
In ques no. 1 I've told you about dead space. Now this air only fills the tract but does not take part in exchange because it does not even reach to the alveoli. So, it remains unchanges and exhaled back. The measurement is 30% . ( 150 ml out of 500 ml, in second ques you have seen the total air taken is 500 ml and dead space has 150 ml of air. Which makes it 30% of the total.)
