Diastolic pressure
Because arteries are narrower, thus increasing the pressure in the arteries. So you need thicker walls to contain the blood under pressure.
True.
That is the Systolic Pressure.
Yes it does.

True.
That is the Systolic Pressure.
Arteries have thicker wall because the pressure in the arteries is much higher.
The elastic walls helps regulate blood pressure.
The more pressure it uses, the thicker the walls will be. Veins have very low pressure which means they have thin walls and vice/versa for arteries which have a higher pressure and thicker walls than veins.
In general, the walls of arteries are thicker than those of veins. The tunic media in particular tends to be much heavier and contains substantially more smooth muscle and elastic tissue. This anatomical difference reflects a functional diffeerence in the 2 types of vessels. Arteries, which are closer to the pumping action of the heart, must be able to expand as an increased volume of blood flows off into the circulation during diastole. Their walls much be sufficiently stong and resilient to withstand such pressure fluctuations. The tunica media is thicker in the arteries mainly for maintaing blood pressure and continuous blood circulation.
systolic, its the number on top, that's why that number is larger
Blood pressure is is sometimes called arterial blood pressure. It is caused by circulating blood on the walls of arteries. When the heart beats, it does not have a constant pressure. It rests slightly in between beats. There is a maximum called systolic and a minimum called diastolic. The pressure is measured in the upper arm at the brachial artery. The BP is expressed in systolic pressure over diastolic pressure in millimeters of mercury (mmHg) and normal blood pressure for an adult is 120/80.
The arterial walls are thicker because they need to withstand the pressure coming from the heart.
The arteries carry oxygenated blood from the heart to the body. The walls of arteries are muscular allowing the arteries to constrict or dilate. The more constricted the arteries are, the higher the blood pressure.
