Arteries always carry blood away from the heart. They also carry only oxygenated blood except for the pulmonary artery. They have thick walls due to the pressure created.
Veins always carry blood towards the heart, they mostly carry de-oxygenated blood except for the pulmonary vein. Vein walls are not so thick.Capillaries are extremely small and its walls are only one cell thick. They join the organ to the vein or the artery, and join the pulmonary vein and pulmonary artery at the lungs.
Arteries- carry blood away from the heart. (I like to think Arteries Away.)
Veins- carry blood to the heart.
Capillaries- connect veins and arteries.
Arteries are the tubes or vessles which carry the blood away from the heart once the blood has been oxygenated by the lungs. When it leaves the heart, it will begin the systematic circut, where the arteries get smaller and smaller, and become capillaries. Capillaries are smaller extensions of arteries and veins, supplying blood tho the bodies extremities. When the arteries deposit the oxygen and other nutrients through the capillaries, the blood then moves to the veins, which will carry the blood back to the heart. The veins are made from all the capillary branches moving back to gether. Veins have lower pressure than arteries, and also carry the deoxygenated "blue" or dark red blood, which will turn back to bright red once the blood is replenished in the heart, where the process starts again. So, * Arteries are the thick tubes carrying oxygenated blood from the heart to the extremities and organs, * Capillaries are the fine branches of arteries or veins which supply blood to the bodies extremities, * and veins are the thinner tubes carrying the deoxygenated blood back to the heart In other words:
Arteries: carry rich blood from the heart
Veins: carry poor blood to the heart
Arteries are the high-pressure side of the vascular system - they are the vessels that are distributing oxygenated blood about the body.
Veins are the low-pressure side of the vasular tree. Veins collect the deoygenated blood, and return it to the heart and lungs.
Capillaries are a network of tiny vessels that provide a junction between the arteries and veins.
Capillaries are bridges between the arterys and veins
The branches from arteries are arterioles and then into capillaries.
Capillaries service cells, arteries and veins transport blood to and from capillaries, respectively.
Capillaries
capillaries actually aren't arteries. arteries, veins, and capillaries are the major blood transport networks. arteries take blood away from the heart, veins take it back, and capillaries go between the two. capillaries are the smallest of these networks tho
Capillaries are smaller, thinner and have less surface area than veins. Veins take blood to the heart, and capillaries are the thin tubes that connect the veins and arteries together.
Veins, capillaries and arteries is that they are all stops for blood.
the three blood vessels are the Veins capillaries Arteries the arteries.
Capillaries.
Capillaries are bridges between the arterys and veins
Capillaries are the structures that connect arteries to veins.
Arteries, capillaries, & veins.
Arteries carry oxygenated blood away from the heart, to the cells that need them. Veins carry blood containing carbon dioxide back to the heart after the oxygen has been given to the cells. Capillaries are the thinnest arteries and veins. They are only one cell wide. As the blood cell passes through the very thin capillary, the cells on either side are given oxygen and carbon dioxide is taken from them. Therefore, the capillaries connect the arteries and veins. Veins are thinner than arteries. Arteries are thicker than capillaries.
Venules, they are smaller and thinner than veins.
Arteries, capillaries, and veins. Arteries take blood away from the heart. Veins return blood to the heart. Capillaries are between the arteries and veins and supply the cells with oxygen and nutrients.

Capillaries. They are the microscopic tubes that connect the veins and the arteries.
