Understand that the visceral mass is a key component of a mollusk's body structure, which contains the internal organs.
Recognize that mollusks are invertebrates with a soft body, often protected by a hard shell, and their body is divided into three main parts: the head-foot, the visceral mass, and the mantle.
Identify the primary functions of the visceral mass, which include housing the organs responsible for circulation, digestion, and reproduction.
Recall that the heart is part of the circulatory system, digestive organs are part of the digestive system, and reproductive organs are part of the reproductive system, all of which are typically found in the visceral mass of a mollusk.
Conclude that the organs typically found in the visceral mass of a mollusk are the heart, digestive organs, and reproductive organs, as these are essential for the mollusk's survival and reproduction.
