What is a median dorsal vessel on a worm?
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.
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.
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 function in the earthworm has a similar function as the human heart?
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.
The function of the earthworms blood vessels?
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)
What do the ventral blood vessels do in earthworm?
the transport blood throughout the worm
What is the function of the dorsal blood vessel of a worm?
i think it carries blood or oxygen to the brain
What does the dorsal blood vessel do in an earth worm?
the main blood vessel in the body
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
What is a aortic arches in a earth worm?
muscular vessels that connect the dorsal and ventral blood vessels.
Where is the dorsal blood vessel located?
The dorsal blood vessel is located on top of the intestinal track in a worm.
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.
