You are all cell experts now so we can start to look at cells in the larger context of our bodies.... what are we made of? Lots and lots of cells! Cells with a common purpose cluster together to make tissues, tissues cluster to make organs, and organs work together to make our systems. And to think it all starts with 2 little cells! As we look at cells and the body in a broader way, you will get a sense of the interdependence of cells, organs, tissues in system function. The human body is an amazing machine!
To start, watch this video. Just how many cells did he say we're made up of?!
The, read this overview. You are NOT expected to learn all the names of all the types of tissue, the organs or the systems right now! A lot of the terms will be familiar but all I want you to do is note is the make-up of tissues, organs and systems. What organs play roles in the different organ systems?
What do you know about the make-up of your body? Quiz yourself with this interactive activity and see if you surprise yourself with how much (or how little!) you know! You might be amazed by just how many organs are living in your little body!
