What kind of lungs does a snail have?
Snails can be divided into two categories when discussing manners of breathing: those with lungs and those with gills. Pulmonate (lung) snails assimilate oxygen through the thin wall (“lung”) of their mantel cavity. Other snails breathe using gills. Snails like the Pond and Ram’s Horn are pulmonate.
How does the breathing valve in a garden snail work?
The valve is used to prevent water loss. This helps prevent the garden snail from drowning and dying. It also helps retain moisture in the snail. The lung is connected to opening on the right side of the mantle cavity, the pneumostome. It is also known as the breathing pore. [1] 3. The breathing pore is where air enters and carbon dioxide exits.
Where is the breathing pore in a snail?
It also helps retain moisture in the snail. The lung is connected to opening on the right side of the mantle cavity, the pneumostome. It is also known as the breathing pore. [1] 3. The breathing pore is where air enters and carbon dioxide exits. 4. The diaphragm’s job is to fill oxygen in the lung and oxygen in the blood. * 5.
How does a garden snail get its oxygen?
How do snails obtain oxygen? 1. Unlike most other gastropods that use gills for respiration, the garden snail uses their lung to exchange gas. They rely on dry air for oxygen.

Where does the respiration take place in a land snail?
Inside the lung, which is a region of tissue where gas exchange occurs, the oxygen is picked up by the blood, and carbon dioxide is emitted – again, just like human respiration. The mantle is a fold of skin that surrounds the snail’s internal organs. Under their shell, land snails have organs and systems just like humans do.
Where are the organs located in a land snail?
Internal anatomy. Under their shell, land snails have organs and systems just like humans do. The animal’s internal organs, which include a digestive gland, lung, heart and reproductive organs, are located within the mantle cavity, inside the shell of the animal.
How does a slug move like a snail?
The slug is a gastropod, which translates to “stomach-foot.” A slug or snail moves by rhythmic waves of muscular contraction on the underside of its foot. At the same time a layer of mucus is secreted, which helps smooth the slug’s path across the ground. Slugs and snails have two pairs of retractable tentacles on their head.
