Question
Chapter 46, Problem 4TYK
Summary Introduction
Introduction:
The respiratory system of insects consists of air-filled tubes called trachea that helps in exchange of O2 (oxygen) and CO2 (carbon dioxide) between the body tissue and air. These tubes penetrate the body of the insects to facilitate gaseous exchange.
