The structures of arteries, capillaries, and veins are all different, because of their different functions. The only way that they are similar is because they are hollow, and have some elasticity.

Capillaries are alot smaller than arteries.
No. Arteries are the largest blood vessels and capillaries are the smallest.
The answer is: c. Capillaries and arteries are similar in size.
A hog's circulatory system is very similar to a human's. They have arteries, capillaries and veins. They also have a lymphatic system.
Large arteries and veins are like high-capacity highways, and they branch into smaller capillaries which go all through the body, so capillaries are like roads.

Arteries have thicker walls than veins because they are carrying blood away from the heart and so, in a sense, are working harder. Veins have thinner walls and contain valves to stop blood flowing backwards.

It is either homologous structures or homozygous structures. Embryological structures are when different species of animals look similar in the earliest stage of development and Analogous structures are when animals look different but their function is basically the same. So just look up homologous structures and homozygous structures in your Bio book!!
