Snail Anatomy Diagram - Internal Organs and Physiology Explained #1917145 (License: Personal Use)

This detailed cross-sectional diagram illustrates the internal anatomy of a terrestrial gastropod mollusk, showcasing its unique organ arrangement-including a single lung (pulmonary cavity), a four-chambered heart, and a complex digestive system with liver, stomach, and intestine. Reproductive structures such as the ovotestis, vagina, and penis are clearly labeled, reflecting the hermaphroditic nature of most land snails. The nervous system (cerebral ganglia) and sensory organs (eye, tentacle) are also indicated.

Used in biology textbooks, educational websites, and classroom materials to teach invertebrate anatomy, especially gastropod physiology and evolution. Matches user intent for learning or teaching basic mollusk morphology.
