1. Cells break down GLUCOSE in order to make ATP Energy!
Mind Stretcher – 1/26/18
Describe Cellular Respiration.
2. What are the reactants (taken in) and products (what’s created)?
Cells break down GLUCOSE in order to make ATP Energy!
Reactants: OXYGEN & GLUCOSE
Products: ATP Energy, Carbon Dioxide, & Water

2. What is our blood made of?

3. What do the components of blood do?
Blood is made up of 4 different components:
Plasma - Fluid part of the blood, consists mostly of water, carries substances such as fats and proteins. carries food & secretions to the cells & carbon dioxide from the cells.
Red Blood Cells (RBC’s) - cells that carry oxygen from the lungs to the body cells and transport carbon dioxide from the cells back to the lungs
White Blood Cells (WBS’s) -destroy bacteria in the blood and fights infection.
Platelets – If you get a cut/injury, a signal is sent to platelets to help blood clot

4. Let’s take a closer look!
Observe the model of blood…what do you think each of these items represents?
Blood is made up of 4 different components:
Water/Plasma
Red squishy beads
White ping pong balls Grey foam
Plasma/Water Red blood cells White blood cells Platelets
Time for some simple math…

5. Blood Cell Basics- Math Worksheet
Take a few minutes to complete the pie chart modeling what’s inside your blood.
Then do some calculations & finish it up. (5 min. max)

6. Background Info
Follow along as we read the class set of sheets provided!

7. Heart Rate Lab
I will time the whole class to complete each exercise for 1 full minute
You need to be QUIET during this time!
After the 1 minute…you will quickly find your pulse.
Start counting the beats when I say “count” and stop when I say “stop.”
Record this info on your lab sheet

8. Question to Discuss…
In addition to your heart beating faster as you exercise…. WHY does your breathing rate increase too?

9. What's lungs got to do with it?
In the lungs, carbon dioxide is removed from the blood and sent out of the body when we exhale. When you inhale, and a fresh breath of oxygen enters the blood to start the process again. This delivery to all your cells happens in about 1 minute!
Without help from the CIRCULATORY system… the oxygen you inhale would never make it to your cells!

10. Now work on your bar graph and lab sheet analysis questions…We will finish the back explanation on Monday! If you didn’t do so already…please try to find out your blood type!
