Artificial Lung Experiment Concepts

The video tutorial demonstrates how to create a homemade artificial lung model using simple materials like PET bottles, balloons, and plastic tubing. The process involves preparing the balloons, constructing air ducts, and assembling the model. The tutorial explains the biological and physical principles behind the model, comparing it to the human respiratory system. The presenter shares a personal reflection on the experiment and provides additional resources for further learning.

What is the primary purpose of the artificial lung in this experiment?

• To simulate the biological and physical aspects of a real lung

• To replace a real lung

• To measure lung capacity

• To filter air

Which material is NOT mentioned as necessary for constructing the artificial lung?

• Plastic tubing

• Balloons

• PET bottle

• Metal sheet

What is the purpose of using a piece of wire in the construction?

• To create a Y-shape from a T-shape

• To reinforce the PET bottle

• To secure the balloons

• To cut the plastic tubing

How is the bottom part of the PET bottle reinforced?

• With hot glue

• With rubber bands

• With a piece of hard wire

• With extra plastic

What is used to check for air leaks in the artificial lung?

• Soap solution

• Smoke

• Blowing air and listening for sounds

• Water

What does the main plastic tube represent in the human body?

• Alveoli

• Diaphragm

• Bronchi

• Trachea

What do the two balloons in the experiment represent?

• Lungs

• Heart

• Stomach

• Liver

What part of the artificial lung represents the diaphragm?

• The wire

• The bottom balloon

• The PET bottle

• The plastic tubing

What happens when the diaphragm (bottom balloon) is pulled down?

• The lungs deflate

• Air is pushed out of the lungs

• Air is drawn into the lungs

• The lungs collapse

Why does air enter the lungs when the diaphragm is contracted?

• Because the lungs expand on their own

• Because the trachea opens wider

• Because the pressure inside the thoracic cavity decreases

• Because the pressure inside the thoracic cavity increases
