Partial pressure is very important for how gases move in our lungs. Here’s how it works:
Moving Gases: Gases travel from places with more pressure to places with less pressure.
Oxygen and Carbon Dioxide: In the tiny air sacs in our lungs called alveoli, there is more oxygen than in our blood. So, oxygen moves into the blood. At the same time, carbon dioxide is higher in the blood, so it moves out into the alveoli.
Getting It Right: This swapping of gases helps us get the oxygen we need and get rid of carbon dioxide, which is essential for our body to work properly.
It's all about that difference in pressure!
