What are the parts of a worm?
The worm is first both male and female the worm is in kingdom Animalia. The worm if you look at on and turn it over on its ventral side (bottom) you will see not to far away from the anterior side which is closet to the mouth the clitellum, it looks little lighter than the rest of the worm and it is not very long. the clitellum is a barrel shaped swelling that starts at the thirty second segment on the worm. this structures aids in the reproduction. Also it can tell us what side is the head and the tail. Talking about the head and the tail there are two different names for the head and the tail end of the worm, the head is called the anterior end and the tail is the posterior end of the tail. Now the first part of the worm is the mouth, the mouth sucks in dirt and then goes to the pharynx ,then through esophagus then trough the crop and then the gizzard and then the intestine then through the rest of the body. worms have two blood vessels dorsal and ventral blood vessel. the dorsal is top and ventral is bottom of the worm. The aortic arches help regulate the blood flow to the dorsal and ventral blood vessels. The nervous system, the worm has a ventral nerve chord running on the ventral side of its body. Telling it what type of surface its on. The worm can tell hot from cold that's why the stay in the dirt to keep cool, that's why is you ever saw a worm dried out on the side walk its because it needs the cool dirt to keep it cool. those are alot of the parts of the worn hope you learned alot from this.
What is the function of a nerve cord in a worm?
While humans and other vertebrates have a spinal column that runs down their back, or dorsal side, earthworms possess a nerve cord consisting of two strands that runs down their belly, or ventral side. The nerve cord of an earthworm relays impulses from receptors in the worm's anterior to posterior parts of its body.

muscular vessels that connect the dorsal and ventral blood vessels.
What is the pathway of the blood through the parts of the earthworm's ciruclatory system?
Earthworms intake oxygen through their skin into the blood of their dorsal vessel. The dorsal vessel carries the oxygenated blood towards the aortic arches in the front of the worm. The aortic arches serve as the worm's heart, pumping blood through the ventral vessel toward the rear of the worm. Smaller vessels carry the blood from the ventral vein to the tissues and back to the dorsal vein.
Where do you find setae on a worm?
