Describe repeated segments, specialized segments, and connections between segments
Repeated Segments: Body segments of annelids except for leeches are divided from one another internally by partitions. Each segment has digestive, excretory, and locomotor organs. The fluid within the coelom of each segment creates a hydroskeleton for rigidity. Due to the segmentation, it is able to expand or contract at any part of the body.
Specialized Segments: Anterior(front) segments of annelids are modified and contain the sensory organs that are sensitive to light; elabrate eyes in some annelids. Also a well developed cerebral ganglion or brain.
Connections between segments: Circulatory system carues blood from one segment to another, while a nerve cord connects the nerve centers, or ganglia, with the brain to coordinate the worm's activity.
