coelenteron

Thân thiện

A simple hydra has a coelenteron for digesting food.

Definition

Noun: * The central digestive cavity of a coelenterate: This is the primary, sac-like body cavity found in animals belonging to the phylum Coelenterata (or Cnidaria), such as jellyfish, sea anemones, and corals. It functions in both digestion and circulation.

Usage

The term coelenteron is a specialized zoological term. It is used to describe the internal anatomy of simple aquatic invertebrates. * It is typically used in scientific, biological, or academic contexts. * It refers specifically to the singular, undivided cavity characteristic of these organisms.

Examples

• The coelenteron of a sea anemone has a single opening that serves as both mouth and anus.
• Food is digested within the coelenteron.
• The structure of the coelenteron is a key feature distinguishing coelenterates from more complex animals.

Advanced Usage

• The coelenteron can be subdivided by mesenteries in some species, such as sea anemones, but it remains a fundamentally simple cavity compared to the complete digestive tracts of higher animals.

Variants and Related Words

• Gastrovascular cavity: This is a more general functional term often used synonymously with coelenteron, emphasizing its dual role in digestion (gastro-) and circulation (-vascular).
• Coelenterate (n): An animal of the phylum Coelenterata/Cnidaria, which possesses a coelenteron.
