This is the last post, so we thought that it could be funny to know some curiosities about The Respiratory System.
1. Horses only breathe through their noses
For humans, breathing through
the mouth comes naturally and easily. The same is for many other
mammals. Horses, have a flap of tissue which prevents them from
breathing through their mouths.
2. Sneeze particles may not
travel as fast as people think
In the past, modeling studies have estimated the velocity of a sneeze at 112 mph (180 km/h). However, a 2013 study found that a sneeze's velocity is even lower than the rates determined.

3. The lungs are the only organs
that can float on water
Each of your lungs contains
about 300 million balloon-like structures called alveoli. When these
structures are filled with air, the lungs become the only organs that can float
on water.
4. Some people can hold their breath for more than 20 minutes
The average time an adult can
hold his or her breath is between 30 and 60 seconds. Stig Severinsen holds
the Guinness World Record: he held his breath underwater for 22 minutes.
5. You lose a lot of water just
by breathing
How much water do you lose
from breathing? When at rest, humans exhale up to 17.5 milliliters
