Capillaries, having diameters between about 0.0005 to about 0.008 inches, are the smallest blood vessels.

No, pigs have a closed circulatory system. Open circulatory systems are used by invertebrates like grasshoppers and other lower-order animals; these systems involve having a beating heart but not a complete 'plumbing' system of arteries and veins - the blood just bathes the internal organs then eventually trickles back into the heart to be pumped around again.
capillaries
The role of the circulatory system is to transport oxygen and other necessary nutrients all throughout the body. The main part of the circulatory system is the heart. The heart is the organ responsible for pumping blood throughout the body. This system has three types of blood vessels: The largest are arteries which go away from the heart. Next are veins which lead to the heart and are the second largest vessel. The smallest are capillaries which transport blood through tight spaces. Sometimes, red blood cells need to pass one by one though capillaries!Wow!The role of the circulatory system is to circulate the blood to the whole body .... basically responsible for the blood flow in the body, oxygen and gases from and to the cells also nutrients and hormones are involved
Blood
The smallest type of blood vessel is the capillary. Its walls are one cell thick and permeable, for substances to transfer out of the capillary and into the cells (and vice versa).

The artery is actually made of three tissues.
The endothelium is the thin layer of cells that line the interior surface of blood vessels,[1] forming an interface between circulating blood in the lumen and the rest of the vessel wall. Endothelial cells line the entire circulatory system, from the heart to the smallest capillary.
I believe the answer you are looking for is called a blood vessel. The system is called a circulatory system.
the dorsal vessel
1) heart 2)blood 3)blood vessel
It is located in the circulatory system being classified as an artery........ Thus it is in there with the heart, and pore....
i really dont know it does not say in any of the science books that i have looked in
No. Veins are the portion of the circulatory system that is responsible for returning blood from the body to the heart. Thus blood flow in veins starts at the smallest capillary vessel and moves to larger vessels.
