I think its dorsal. REALLY sure.
The dark line on the dorsal side of an earthworm is called the dorsal blood vessel or the dorsal blood vessel line. It is part of the earthworm's circulatory system and helps transport blood throughout its body.
yes.
the main blood vessel in the body
it the blood vessle in the doral fin of a fish
I always got dorsal (down the back or spine) and ventral (down the underside) confused, until I thought of an easy way to remember it. The ventral goes down to where the animal "vents" (poops). So the dorsal blood vessel is the vessel that runs down the back, while the ventral blood vessel runs down the underside.
digestive
it carries blood from the dorsal blood vessel to the ventrical blood cell
The median dorsal vessel in a worm is part of its circulatory system that runs along the dorsal midline of the body. It functions to transport nutrients, waste products, and gases throughout the worm's body.
To carry the blood to all parts of the earthworm.
There are two. The main one which is viewable through the skin is the dorsal blood vessel. The smaller one found under the intestine is the ventral blood vessel.
This artery is called the dorsal aorta and it is a main artery leading from the heart. It divides and branches out to smaller arteries that ensure that all of the body is supplied with oxygen.
