Simple Biology Practice of Breathing

Simple biology practice of breathing this time about how to make artificial lungs or how the lungs breathe. Breathing is inhaling oxygen and removing carbon dioxide. make our artificial lung we certainly make our junior time. To remind us again about
how to make artificial lungs then I will explain how to step by step how to make artificial lungs.

Materials Needed :

1. Ballon
2. mineral water bottles
3.scissor
4. duct tape
5. straw

 How to make :

1. prepare the ingredients first.
2. empty aqua bottle scissors or no half water.
3. hatch the aqua bottle cap over a large marker with a heated spike
4. insert the straw into the bottle that has been perforated. before that combine straw 1 with 2 straws coupled with duct tape to form Y
5. connect the straw that forms Y to the main straw
6. attach the balloon to the Y-shaped straw.
7. on the bottom or cover of aqua bottle on the lid with black tape
8. when finished to play it simply by pulling the balloon repeatedly if successful then the balloon inside will expand and shrink.

The conclusion of the Praktek Biologi Sederhana can be concluded that when the balloon is pulled down the lungs will expand and when the balloon is released then the lungs will shrink.
