Veins branch at their beginnings into tiny venules which join capillaries.  Veins have valves which stop the blood from flowing backward. Compared to the arteries, pressure in the veins is very low. The blood is being pushed through the arteries as the heart squeezes the blood out. This is not true for the veins. Blood is pushed through the veins when body muscles contract and squeeze the veins.
Thanks for the question. The radial artery in the wrist can be used to measure the blood pressure. But in my opinion, the brachial artery blood pressure measurement is better than radial artery for the following reasons: 1.The blood pressure at the wrist is higher for systole, lower for diastole, and about the same for mean or average pressure. The amount of difference depends on the stiffness of the arteries.ut in my opinion, the brachial artery blood pressure measurement is better than radial artery for the following reasons: 1.
