Yes
Yes, that is correct.
The arterial walls are thicker because they need to withstand the pressure coming from the heart.
Have thinner walls.
Venules, they are smaller and thinner than veins.
Arteries have thicker wall because the pressure in the arteries is much higher.
Thee difference between muscle in veins and arteries is that muscles of arteries are thicker compared to those of veins.
Most veins are thinner walled tubes than arteries, and basically transport blood towards the heart.
Arteries have thick elastic walls that can expand and contract, because they carry blood pumped from the heart. Veins return the blood to the heart but the pressure is not the same as in the arteries.
Capillaries are thin tubes connected to your veins and arteries that transfer the blood from the arteries to the veins. Capillaries are so thin, they are thinner than one piece of hair. They are one cell thick.
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 have thinner walls compared to arteries. They also have larger lumens than arteries which is the space inside the vessel. Lastly they have one-way valves to help keep the blood flowing in one direction.
Pulmonary Arteries lead from the heart to the lungs. Systemic arteries go everywhere else. Consequently, the pulmonary arteries are usually slightly smaller and thinner. There is also less of them.
