Subject: 'Fast Facts' on the circulatory systems of the tiger, snake, and jaguars.

I am a teacher of students K-5 with learning disabilities. One group has taken 
on the project of comparing the human circulatory system to that of animals that 
interest them. Unfortunately, none of our available resources, including a 
well-stocked school library, a plethora of CD-Rom encyclopedias etc, internet 
sites, or our resident biology expert, has ANY information on the circulatory 
systems of animals, and certainly not any detailed information. The two girls 
doing this project have average intelligence but low reading and writing levels. 
They are creating a spreadsheet in order to compare different aspects of all of 
these various animals' circulatory systems. (there is another group comparing 
skeletal systems but they have yet to ask me about finding info on the internet!). 

These students are fourth and fifth graders. Could you please help us or steer 
us towards resources that would help?  Their request is below so that you can 
respond to it. Thank you for any help you are able to provide.

Do you know anything about the tiger, jaguar and snake? We're trying to
compare the tiger heart to our heart, and the jaguar heart to our heart.
We're doing the same with the snake. 

We'd also like to know the following:

We want to compare how much blood the kidneys filter in these animals. 
How much do the tiger's lungs weigh? 
How much air do all the animals' lungs hold? 
How much blood can the heart hold? 

Please email us as soon as you can.
Thank you!
