Veins have thinner walls compared with arteries. They conduct blood (that has given up most of its oxygen) toward the heart from the tissues. Veins have little elastic tissue and less connective tissue than that typical of arteries, and blood pre...

venous pressure- the pressure exerted on the walls of the veins by the circulating blood circulation- movement through a circuit; especially the movement of blood through the heart and blood vessels force per unit area,pressure,pressure level- the force applied to a unit area of surface; measure...
For example, blood pressure in the capillaries is usually about 20 to 30 mmHg, whereas the pressure in the large veins may become negative (lower than atmospheric pressure [760 mmHg at sea level]; technically, measurements of blood pressure are relative to atmospheric pressure, which represents ...
Veins carry blood back to your heart from the rest of your body. The pressure of the blood returning to the heart is very low, so the walls of veins are much thinner than arteries. Capillaries are tiny blood vessels that connect arteries and veins. Their walls are very thin. The blood ...

In the rhythm of life’s heartbeat, the strength of blood coursing through our veins often goes unnoticed. This pressure, known as blood pressure, plays a pivotal role in our overall health. High blood pressure, medically termed hypertension, is a condition that raises alarms for numerous healt...
For example, if the blood pressure is elevated, the sympathetic nervous system is inhibited and the parasympathetic nervous system is activated. Stimulation of the parasympathetic nervous system causes the heart rate to decrease, the vascular tone of the veins to decrease and thus the central blood...
