      Really the whole body interacts together as one whole but we like to break things down into systems to make them easier to understand sometimes. The main ones I can think of are reproductive, respiratory, circulatory, nervous and digestive systems.

      We have lots of different systems which make up the human body. I had to do a quick google search to check I had all of the systems and found the following information… apparently we have 11 systems in our bodies (which is far more than I could think of)!! We have: circulatory, respiratory, digestive, excretory, nervous and endocrine systems, along with the immune, integumentary, skeletal, muscle and reproductive systems. There is an explanation of all those here if you wanted a little more information: http://study.com/academy/lesson/what-are-the-organ-systems-of-the-human-body.html

      Ellen mentioned that they are many systems indeed! And the systems also work together to make the body functional.

      The immune system is something I am particularly interested in as I have seen it working in the chickens when I was doing some research on it. We can learn alot about our own immune system by starting that of other species: we share more than half our genes with chickens.

      The immune cells are just like secret agents on a mission to prevent spies from infiltrating the body. Just thought I’d share this video that I have recently done with a friend:

      Both Ellen and Carrie answer perfectly. We ave several different systems that together help our bodies work like finely tuned machines.

      Define what you mean by “system” 🙂 The body is a system. There are infinite systems within it depending what you draw a circle around. The body itself is reliant on its environment – making a bigger system. James Lovelock suggested the whole world could be thought of as a single living organism – a giant ecosystem. He called it the Gaia hypothesis. So does it matter how many systems we have in our body or how we define them? Or is it more important how our bodies interact with our environment.
