Blood flow in arteries and veins - Pedley - 2000 () Citation Context ...We note that this type of instability is distinct from those relevant to flows in constricted two-dimensional channels, where ‘vorticity waves’ and shear-layer instabilities are observed (Sobey 1985; =-=Pedley 2000-=-...

In humans, blood pressure is usually measured indirectly with a special cuff over the brachialartery(in the arm) or the femoral artery (in the leg). There are two pressures measured: (1) thesystolic pressure(the higher pressure and the first number recorded), which is the force that blood...
Vein vs Artery.Veins are closer to the surface of your body, and arteries are deep inside your muscles. The walls of a vein are thinner than an artery. Veins carry blood from your organs and towards your heart. Arteries carry blood away from your heart. Vein vs Capillary.Veins have thick...
Blood vessel, a vessel in the human or animal body in which blood circulates. The vessels that carry blood away from the heart are called arteries. Veins are vessels that return blood to the heart. Learn more about the anatomy and types of blood vessels
Arterioles carry oxygenated blood from arteries to capillaries. They have thick walls that contain a lot of smooth muscle. Venules carry deoxygenated blood from capillaries to larger veins. They have much thinner walls than arterioles because they experience a much lower pressure.Types...
(redirected from blood pressure classification)Also found in: Thesaurus, Medical, Encyclopedia. blood pressure n. Abbr. BP The pressure exerted by the blood against the walls of the blood vessels, especially the arteries. It varies with the strength of the heartbeat, the elasticity of the ...
Stage 1 – Systolic 130 to 139 mmHg or diastolic 80 to 89 mmHg Stage 2 – Systolic at least 140 mmHg or diastolic at least 90 mmHg If there is a difference in the category, the higher number determines the level of high blood pressure. In Europe, hypertension is defined differently. The...
blood pressure, whereas blood flow to vital organs can still be compromised. Compensated shock, defined as reduced perfusion without arterial hypotension, is especially common in children. In children, heart rates can be inappropriately high or low for age (infants: <90 or >160/min; children <...
In the last stage, vessel features at intersection and bifurcation points are processed for detection of arterial and venular sub trees. Ultimately vessel labels are revised by publishing the dominant label through each identified connected tree of arteries or veins. Evaluation of the proposed ...
