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.
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
Arterioles take blood from the arteries to the capillaries. Venules take blood from the capillaries to the veins.
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.
