veins carry blood with high concentrations of waste products and arteries carry blood with high concentrations of nutrients
no veins carrys blood towards the heart
Blood in the arteries has a higher concentration of oxygen and nutrients than venous blood. The veins are returning blood to the heart after these components have been delivered to the body tissues.
Oxygen.
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.
They both carry, or transport blood or nutrients to where the body or plant needs.
The veins are what transport key nutrients to the rest of the body's systems. Without the veins, the body systems would not function. For example, the veins have pathways to the brain which relies entirely on the many nutrients the blood provides it.
Arteries have a smaller lumen (centre passage) than veins do, they also have thicker more 'muscular' walls than veins do. This is because blood pressure is higher in arteries than in veins, as arteries carry blood away from the heart, veins carry blood to the heart, pressure has to be high in arteries so that blood can reach all around the body.
The pulmonary veins carries oxygen rich blood from the lungs to the heart.
Blood is transported in arteries, veins, and capillaries. Arteries are the vessels that take blood from the heart. Veins are the vessels that take blood back to the heart, and capillaries are the tiny vessels that attach the arteries and veins. Transport of oxygen and nutrients occurs on the capillary level.
Veins don't carry blood at high pressure arteries carry blood at high pressure. Arteries have a thick, elastic muscle layer that can handle high pressure of the blood flowing through them.
The vein of a plant and human are alike because each one carries either blood or nutrients to the main part of either the human or plants body.
