I have to draw the digestive system to scale and I am having a difficult time finding accurate sizes of the organs. Please help!

What type of muscle tissue lines the digestive system organs?

Describe the path that blood takes throughout the circulatory system.Be sure to use the names of the major organs and blood vessels involved.
In paraphrasing and words we can UNDERSTAND pleaseeee.

Do all of the organs in both human and frog digestive system have similar functions?

Also, do frogs have an acidic stomach, like humans?

I’m supposed to make a list of the major system of the body and list the functions of the major organs. Anyways, I started to wonder if the cardiovascular and the circulatory system were considered the same thing or if cardiovascular was mostly heart and the circulatory was mostly vessels and such.

Doing homework for Anatomy and Physiology (so much or enjoying the holidays, eh?) and unfortunately, the instructor doesn’t have enough books for us all to have one of our own. So now I’m stuck with a paper full of questions we were to copy, and few answers. This one I just can’t figure out, nor find it on the Internet. It’s not made up of organs but…why is the skeletal system an organ system?

Sources would be appreciated!
