Describe the differences in structure between an artery and a vein ...
Veins, on the other hand, have a thinner tunica externa (the tough outside layer) because the blood pressure within the vein is less than the blood pressure in the artery. They have a …
Outline the differences between arteries and veins? (6) marks
Outline the differences between arteries and veins? (6) marks- 3 for each Arteries and veins are the "tubes" that carry blood around the body.Artieries have thick outer walls in order to cope …
Why do different blood vessels have different lumen sizes
Arteries have to carry oxygenated blood away from the heart to the tissues at high pressure. Small lumen (relative to the large, muscular vessel) ensure this pressure is maintained as the …
What is the difference between an artery and a vein? - MyTutor
Arteries and veins both carry blood around the body, and they each have three main layers of tissue (a ring of endothelial tissue at the centre of the blood vessel surrounded by a layer of …
What is the difference between arteries, veins and capillaries?
Arteries, veins and capillaries are all types of blood vessels. The best way to think about their differences are the roles they play in circulation. So, if we take the systemic circulation as an …
Name two structural differences between arteries and veins.
Arteries have thick, elastic, muscular walls whereas veins have thin walls with few elastic fibres. Arteries need these properties to give them the strength and elasticity needed to cope with the …
What’s the difference between arteries, veins and capillaries?
They also contain valves, to prevent backflow of blood. Arteries transport oxygenated blood, except for the pulmonary artery, while veins transport deoxygenated blood, except for the …
What are the differences between the structure and function of …
Arteries have a narrower lumen (the space through which blood flows), in order to keep the blood at a higher pressure. Veins are the blood vessels that carry blood back towards the heart. …
Compare the structural differences between arteries, veins and ...
In arteries, the main structural difference is the thickness of the arterial wall, due to an increased amount of smooth muscle, arteries have much thicker walls than both veins and capillaries to …
What is the difference in structure between arteries and veins?
Veins, on the other hand, contain little muscular or elastic tissue so have a much thinner wall and relatively larger lumen. Because the the blood in veins is flowing under very low pressure, …
