The Mantle
Mollusks generally have a soft body enclosed in a protective shell made of calcium carbonate. The body consists of a muscular foot for movement, a visceral mass for digestion and reproduction, and a mantle that secretes and maintains the shell. Some mollusks, like snails, also have a radula for feeding.
Between the mantle and the visceral mass in mollusks lies the pallial cavity. This space plays a crucial role in housing the gills or lungs and allows for the exchange of gases and waste. It also facilitates the expulsion of water and other materials from the organism. The pallial cavity is essential for the mollusk's respiratory and excretory functions.
Yes, the pleura is a thin double-layered membrane that surrounds the lungs. It is considered a visceral organ because it is an internal organ that is closely associated with the lungs.
No. There are different classes of mollusks. Gastropods (shell-less or single-shelled), Bivalves (2 shells held together by 1 of 2 powerful muscles), and Cephalopods (Small internal shells or no shells at all)
Visceral mass of mollusks contain all organs but head foot and gills . Thus vascular , excretory reproductive , part of nervous and digestive functions function are performed by visceral mass .
They have a mascular foot, a visceral mass, and a mantle.
Foot,visceral,mass and head
The thin folded membranous tissue that envelops most of the visceral mass in mollusks is called the mantle. The mantle is common on all mollusks, including those that live in freshwater.
visceral mass you lazy odysseyware student ;)

I don't think they do...I could be wrong but I think all mollusks have a foot, visceral mass, and a mantle.
They all possess a soft portion of their body known as the visceral mass.

A snail does have a visceral mass
The visceral pericardium is the outer sac that surrounds the heart. Another name for the visceral pericardium is the endocardium.
