It is a vein.
They are called capillaries.
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.
The dorsal blood vessel is located on top of the intestinal track in a worm.
its a tiny blood vessel, so at one end would be the larger blood vessel and on the other end would be the portion of the body part it is supplying with oxygenated blood
As blood enters the capillary bed on the arteriole end, the blood pressure in the capillary vessel is greater than the osmotic pressure of the blood in the vessel. The net result is that fluid moves from the vessel to the body tissue.At the middle of the capillary bed, blood pressure in the vessel equals the osmotic pressure of the blood in the vessel. The net result is that fluid passes equally between the capillary vessel and the body tissue. Gasses, nutrients, and wastes are also exchanged at this point.On the venue end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel.
The answer is the vein
Yes it is located at the inferior end of the ascending colon.
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)
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.
Yes, capillaries are fed by arteries at one end. Capillaries connect small arteries to small veins.

A blind-ended vessel is a vessel that is closed at one end, or has a 'dead end'. They can be found in the lymphatic system, for example.
