Verified step by step guidance

Understand the anatomy of a worm: Worms, such as earthworms, have a segmented body structure. Each segment is separated by septa, and the internal organs are distributed throughout these segments.

Identify the coelom: The coelom is a fluid-filled cavity within the body of the worm. It acts as a hydrostatic skeleton and houses most of the internal organs, providing space for organ development and function.

Recognize the role of the coelom: In worms, the coelom is crucial for the distribution of nutrients and waste products, as well as for the movement of the worm, as it allows for the expansion and contraction of muscles.

Differentiate between body segments: The anterior segment is the front part of the worm, containing the mouth and sensory organs. The clitellum is a thickened, glandular section of the body involved in reproduction. The posterior segment is the rear part of the worm.

Conclude that the coelom, which spans across multiple segments, is where most of the internal organs are located, providing a protective and functional environment for these organs.
