What else can I help you with?
Is the dorsal blood vessel or ventral blood vessel larger in earthworms?
I think its dorsal. REALLY sure.
Is the dorsal blood vessel different from the ventral blood vessel in an earthworm?
yes.
What is the dorsal blood vessel and the ventral blood vessel?
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.
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.
What is a median dorsal vessel on a worm?
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.
How can you tell the difference between the dorsal and ventral sides of a squid?
the dorsal is along the back and is darker from the main blood stream, where as the ventral is along the front and is very light from the less blood in the certain vessel....so yeah
Which side is darker on woodlice the dorsal or ventral surface?
The dorsal side of an earthworm is darker than the ventral side. This is because of the dorsal blood vessal that runs along the top of the digestive track and just under the skin. There is a ventral blood vessel, but it doesn't lie against the skin, but instead in between the ventral nerve cord and the digestive track.
What blood vessel carries blood away from the heart of a 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.
What is the dark line on the dorsal side of the eartworm called?
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.
Dorsal blood vessel?
Blood moves through the ventral blood vessel to the posterior of the body and through the dorsal vessel to the anterior of the body. The dorsal blood vessel contracts to push the blood back and then forward to the ventral vessel where a series of aortic arches act as hearts to move blood forward to the anterior end and through the capillaries.
Why do earth worms have a circulatory system?
An earthworm has a circulatory system consisting of four or more ventral blood vessels and one dorsal blood vessel that is also its heart. Most of the pumping of blood is performed by general muscular movements.
What is the difference between the dorsal and ventral sides of the worm How can you tell which side is which?
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
