The expansion and contraction of the arterial walls is the pulse.
The arterial and capillary walls are incredibly strong. This is true otherwise you would be bleeding just by tapping yourself.
atherosclerosis.
arterial walls has smooth muscle and elastic fibers (strong and flexible) and capillaries are made up of a single layer of endothelial cells (thin).
The stretching of the arterial walls is called arterial dilation or vasodilation. This process occurs when the smooth muscle in the arterial walls relaxes, allowing the blood vessels to widen and increase blood flow. It is a crucial mechanism for regulating blood pressure and ensuring adequate perfusion to various tissues in the body. Factors such as increased blood flow, hormonal signals, and certain medications can trigger arterial dilation.
Pulse
Because the arterial walls begin to harden and plaque formation increases within the walls of the arteries.
An arteritis is an inflammation of arterial walls, often due to infection or an autoimmune response.
The arterial walls are thicker because they need to withstand the pressure coming from the heart.
This is the force of the blood being pumped in an artery pressing against the arterial walls.
Aids
Much lower... because arterial walls get their pressure via force of the left ventricle pumping into the arteries. Veins are not exposed to such force and get their pressure via muscle pumps.Much lower... because arterial walls get their pressure via force of the left ventricle pumping into the arteries.
