Nervous system - Brain - a center of nerve cells that coordinate all of the activities of the worms body - Ventral nerve cord - A cord of nerves that runs the length of the body along the bottom or belly of the worm. All nerve impulses to and from the brain are carried din this cord Circulatory System - Aortic Arches - a group of 5 muscular tubes that pump blood through the circulatory system of the worm - Ventral blood vessels - a tube structure that carries blood from the heart to the posterior of the worm located on the bottom of the worm - Dorsal blood vessel - gathers blood from the capillaries in the body and returns it to the heart for recircutation located in the back or top of the worm Reproductive system - Seminal Vesicles (openings) - male reproductive organs - Ovary (oviduct ovaries) - egg sack, female reproductive organs - Seminal Receptacles (openings) - temporary storage areas for the male sperm until the eggs are ready to be fertilized Other Systems - Nephridium - coiled tubes in the body of a worm that collect and excrete liquid wastes from the body of the worm. - Clitellum - a swollen area of band around the mid section of the body of the worm. Materials secreted from the clitellum form a cocoon in which the eggs are hatched and the young worms develop. - Setae - Bristle structures found on the skin of the worm. Four pair of Satae are found on each segment except the first and last. Satae are used for movement. - Segments (somites) - The divisions in the skin of a segmented worm.
