What are the 3 types of worm body cavities and their description?
Three types of worms with different body types will be explored in this lesson: Flatworms, which have ribbon-like bodies with no body cavity. Roundworms, which have a body cavity but no segments. Segmented worms, which have both a body cavity and segmented bodies.
What is body cavity in animals?
A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity.
What type of body cavity do flatworms have?
Flatworms have no true body cavity, but they do have bilateral symmetry. Due to the lack of a body cavity, flatworms are known as acoelomates.
What has a pseudocoelom?
The hydrostatic pressure of the pseudocoelom gives the body a supportive framework that acts as a skeleton. Nematodes or roundworms (see Nematoda), rotifers (see Rotifera), acanthocephalans (spiny-headed worms), kinorhynchs (see Kinorhyncha) and nematomorphs or horsehair worms (see Nematomorpha) are pseudocoelomates.
What are the 3 types worms?
Worms are classified into three major phyla, or groups. They are flatworms, roundworms, and segmented worms.
What are the 3 classes of phylum Platyhelminthes?
The Platyhelminthes includes three classes: the Turbellaria (free-living flatworms), the Trematoda (flukes), and the Cestoda (tapeworms).
What are the 3 classes of flatworms?
Phyla Platyhelminthes and Nemertea. The Platyhelminthes includes three classes: the Turbellaria (free-living flatworms), the Trematoda (flukes), and the Cestoda (tapeworms).
What is Coelomic cavity?
The coelom (or celom) is the main body cavity in most animals and is positioned inside the body to surround and contain the digestive tract and other organs.
What are Class 3 worms?
Worms are invertebrates and may have long, skinny bodies. There are several different types of worm species, but most worms can be put into one of three categories: flatworms, roundworms, and segmented worms. Many worms are parasites and live in or on other animals.

What are the two body cavities in the ventral cavity?
The ventral cavity also contains the abdominopelvic cavity, which can be separated into the abdominal and the pelvic cavities. Vertebrate animals have two major body cavities.
