Answer:Because arteries are the first vessels that the heart pumps blood through, they experience the highest blood pressure, so they have thick elastic walls to withstand the high pressures. Small arteries, such as arterioles, are less elastic and have more smooth muscle than the larger arteries.
When the rate of blood flow becomes too rapid, or fast blood flow passes on damaged endothelium, it increases the friction within vessels resulting in turbulence and other disturbances. According to the Virchow's triad, this is one of the three conditions that can lead to thrombosis
Slow or poor blood flow will cause your hands and feet feel much colder than the rest of your body. When your blood is flowing at optimal speed it helps to keep your body’s temperature at a healthy and comfortable level. If your circulation is poor, the process of regulating temperature is interfered with.
Low blood volume leads to tachycardia because the heart is trying to overcompensate for the lack of blood volume in the body 1. It causes the heart to overwork, beating quicker and quicker to try to keep enough blood going to extremities
If it’s too high, it can cause arteriosclerosis, a condition that hardens your arteries and can help choke off blood flow. Aim for 120 over 80 or less, but ask your doctor about the best numbers for your age and health. Check your reading at least once a month. You can buy a home blood pressure monitor or use a kiosk at your pharmacy.
