Question

How do 2 different animals perform positive pressure and negative pressure breathing?

Expert Solution

Step 1

The process of breathing is based on the difference in air pressure between the environment and the lungs.

Positive pressure breathing refers to the breathing system in general amphibians such as frogs. These animals push air into their lungs by actively moving their throats. It creates higher pressure in their throat. It leads to the passage of air into the lungs where the pressure is low. After entering the lungs, air undergoes gaseous exchange in the alveoli. Here, oxygen is diffused in the body while carbon dioxide takes exit from the body.
