Gas+Exchange

**Wow, nice work, this is the final area you must research before you are able to rescue your uncle.**

1. Blood: what is blood made of and is it all the same?

2. The Circulatory System: how does blood move around the human body and what does it move in?

3. The Respiratory System: what happens when we breathe and what is involved in this process?

4. Gaseous Exchange: how does oxygen from the lungs enter the blood and then muscles and other organs?

__ //**Gas Exchange, lets get to it!**// __

**Task 4A**: The class has been split into four groups, in your groups you have been given one of the following areas:
 * Circulatory system structure
 * Circulatory system function
 * Respiratory system structure
 * Respiratory system function.

Before we look at gaseous change we are going to create a brainstorm, your group will be responsible for brainstorming all the ideas you can think of that relate to your area. This is to refresh our memory on both the respiratory and curculatory systems. To begin the brainstorm click on the link below.

Body Systems Brainstorm

We will be returning to this brainstorm as we learn more about the other systems within the human body such as the digestive system.

**Task 4B:** Now that we have reviewed what we know about the circulatory and the respiratory systems lets see how they work together to make our body work. The key interactions between these two systems that allows our bodies to function is that of gas exchange. To get a quick idea of what this is, follow the links below and complete the both the activities. Again use the username and password you have been provided with previously to access these links.
