What is the function of thick walls for the arteries?

When blood comes out the left ventricle, it comes out at pretty high pressures. This high pressure is needed to make sure that the blood reaches all the capillaries in the body. Imagine if blood came out at low pressures! It would just stop halfway. So nothing for our toes, then? read more

A: Arteries have much thicker walls than other blood vessels in order to withstand the higher blood pressure that propels oxygenated blood away from the heart. Arteries are also supported by thick muscles and elastic fibers, unlike veins and capillaries, which are subjected to a much lower level of blood pressure. read more

The function of capillaries is to allow food and oxygen to diffuse to cells while waste is diffused from cells. Capillaries have thin walls - only one cell thick - that allow them to effectively perform their function. read more

haha Anyways, the thick arterial walls especially in the aorta are meant to withstand the high pressure of blood flow. If they weren’t thick, they would simply burst. Venous blood flow is under alot less pressure, and therefore veins do not need thick walls. read more

Arteries. Blood in the arteries is under high pressure generated by the heart. The arteries have: thick outer walls ; thick layers of muscle and elastic fibres. Veins. The blood in veins is under lower pressure than the blood in arteries. The veins have: thin walls ; thin layers of muscle and elastic fibres. read more
