- Hey! Bob do you know what homeostasis is?
- ROOF
- How about I show you an experiment that I'm working on for school.
- Step 1: You need to find your pulse. To do this you place 2 fingers on your wrist between your bone and tendon. Count how many times your heart beats per minute and write that down as your resting heart rate.
- Well, I guess you don't have fingers but that's ok. You can find a your pulse on your ribs behind your left and right elbow.
- Step 2: Next you do 10 squats, you can just do any exercise, Bob. When you are done find your pulse again and count your beats per minute.
- Ok, this is actually pretty hard...
- Ok, just...a...few..more...
- Step 3: After this you have to get a stopwatch... *huff puff*
- Step 4: And calculate the time it takes for your pulse to go back to normal. Ugg, ok I'm done.
- And then 30 squats.
- And then repeat the steps again but with 20 squats.
- See how after you do the squats your heart rate increases. Your heart rate eventually goes back to normal, that's an example of homeostasis.#160;
- Bob, did you hear that? Bob? You better be doing the experiment. It's more accurate with more than 1 trial!
- So your body does this automatically and an example of this is when your heart rate increases and eventually returns to normal. That's your body maintaining homeostasis!
- Homeostasis is the state of steady internal and external conditions maintained by living systems in order to survive.
