Generalities

   

This website gives general information on many fields of study including History, Political sciences, Medicine,Philosophy, Science and so forth...Each field has several subdivisions, which are also divided into different groups.The Science subdivision contains a zoology webpage which leads to a webpage on insects. Your link will give you generalities on insects and introduce you to  their main systems which are enumerated and described below.

 Respiratory system

This webpage is an extract of an online textbook written by John W. Kimball, retired professor of biology. The textbook website is index-like organized. If you want to know about a specific term, just click on the letter your term start with it, and you will find it in the alphabetically organized list of words starting with the same letter. This link will lead you directly to a page that  has  ample informations on the respiratory system of insects.  You will learn about tracheal breathing, ventilation of the tracheal system, and gas exchange in aquatic insects. 

 


 


To help 

you understand the mechanism better, watch this animated representation of respiratory movements in insects.

Circulatory System



Created by John R.Meyer,this website offers an entomology class that covers some of the chapters you will be studying in this class. Ten modules discuss collection techniques, importance of insects, taxonomy, external anatomy of insects...You will be redirected through this link to a webpage on the circulatory system of insects. it will discuss its composition and mode of action.




Nervous System


Originally posted trough the entomology website of  the university of North Carolina at Ashville,  this Link will  redirect you to a lecture on insects' nervous system. The presentation  is very concise but filled with explanatory diagrams that will help you understand and remember the concepts better. You will also learn about the sense organs, particularly the eyes. 

 


 



Digestive System

This powerpoint presentation was found on the website of Dr Ron Aiken of the mount Allison University.The website contains several biology courses and presentations including one on insects. The presentation is mainly images and diagrams illustrating what you learned in class.



Reproductive System


This powerpoint presentation was extracted from the website of City Groove College. It is an awesome lecture on insect reproductive system. Both male and female modes of reproduction are thoroughly  described. You will get ample yet non overwhelming information.
