How Do Snails Breathe Underwater

Snails are able to breathe underwater by using a process known as countercurrent exchange. This process allows the snail to exchange oxygen and carbon dioxide between its body and the surrounding water.

The countercurrent exchange system works by having a blood vessel that runs along the length of the snail’s body. This vessel is divided into two sections with one section containing oxygenated blood and the other containing deoxygenated blood.

As the snail moves through the water the oxygen-rich water flows over the blood vessel and comes into contact with the oxygen-poor blood. This causes the oxygen to diffuses across the blood vessel and into the blood. At the same time the carbon dioxide in the blood diffuses into the surrounding water.

This process ensures that the snail’s blood is constantly oxygenated even when it is underwater. It also allows the snail to get rid of the waste products of respiration such as carbon dioxide.
