muscular vessels that connect the dorsal and ventral blood vessels.
i think it carries blood or oxygen to the brain
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.
The median dorsal vessel on a worm carries the blood to the anterior end of the worm, while the median ventral vessel carries the blood to the posterior end of the worm.
The dorsal blood vessel is located on top of the intestinal track in a worm.
the main blood vessel in the body
the transport blood throughout the worm
Blood vessel on the bottom of a worm Blood vessel on the bottom of a worm
The earthorm has a closed circulatory system with five main blood vessels:Dorsal (above the digestive tract) - it moves blood forwardThe remaining four all move the blood to the rear of the earthworm: Ventral (beneath the digestive tract)Subneural Vessel (below the nerve cord)Right & Left Lateroneural vessels (either side of nerve cord)
The actual "pumping system" of a worm can be mistaken as a heart, but it has no chambers. They are actually aeortic arches that pump the blood down the ventral side of the worm and it returns on the dorsal vessel.
They have hearts with blood vessels that pump the blood to the rest of their body
You can tell cause dirt comes out the dorsal side. the dorsal side is darker because its the worms main blood vessel like our aorta
