The Human Body
This website offers many different types of images for the human body and even specifies them based on their bodily system. As a teacher, I could use this website to see how to break the systems into different parts and also allow the students to see what the organs that make up the certain system look like as well. This could be combined with the cell images to show the information going from specific to the board or vice versa. This also allows the students to see which organs belong to which system and the purpose they have in that specific system.
