Let's answer the week's question ---> what is the conducting system?
To answer this week's question you had to pay attention to the framework of the question as well as the question itself, in other words, it probably helped if you noticed that the question came to us from the realm of anatomy. So in anatomy, the conducting system refers to the pathways air travels through to reach the lungs. Included in this system are the nasal cavity, pharynx, larynx, trachea and bronchi.
Find this question (and answer) as well as a ton of other anatomical information - and really, cool, very detailed illustrations in The World's Best Anatomical Charts. The book is published by Lippincott Williams & Wilkins and is copyrighted 2000. I found the information on page 6.
