it drains blood from the nerve cord n' stuff :)
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)
yes.
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.
To carry the blood to all parts of the earthworm.
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.
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.
The function of an earthworm's aortic arches are to pump blood to the ventral blood vessel and into the body.
the aortic arches are the earthworms pumping organs. Basically like a heart for them. For example us humans have a heart and arteries to help pump blood in and out of our body. The earthworm has 5 aortic arches located all around its body to help circulate blood around the body
Yes, a earthworm does have blue blood.
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.
No, they only have a ventral blood vessel.
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.
