What is a aortic arches in a earth worm?
muscular vessels that connect the dorsal and ventral blood vessels.
What is the function of the dorsal blood vessel of a worm?
i think it carries blood or oxygen to the brain
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 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.
Where is the dorsal blood vessel located?
The dorsal blood vessel is located on top of the intestinal track in a worm.
What does the dorsal blood vessel do in an earth worm?
the main blood vessel in the body
What do the ventral blood vessels do in earthworm?
the transport blood throughout the worm
What is the function of the ventral blood vessel of a worm?
Blood vessel on the bottom of a worm Blood vessel on the bottom of a worm
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 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.
What body structure causes blood circulation in the worm?
They have hearts with blood vessels that pump the blood to the rest of their 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
