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
What is high blood pressure (hypertension)? High blood pressure (hypertension) is defined as high pressure (tension) in the arteries, which are the vessels that carry blood from the heart to the rest of the body. Blood pressure measures the force inside the body’s arteries that happens with...
In the veins, the smooth muscle and connective tissue layers are thin, which makes the walls thin and thus allows more blood to flow through. This is because the blood in the veins has lower pressure as compared to the arteries in which the walls are thicker. This allows the veins to ho...

Ventricular contraction ejects blood into the major arteries, resulting in flow from regions of higher pressure to regions of lower pressure, as blood encounters smaller arteries and arterioles, then capillaries, then the venules and veins of the venous system. This section discusses a number of ...
Blood pressure is the pressure that circulating blood in the bloodstream exerts on the walls of the blood vessels. There are two main types of blood pressure: Systolic pressure is the pressure that is measured in the arteries as your heart contracts, while diastolic pressure is the pressure ...
Differentiate how the blood pressure is controlled in arteries versus veins. Fluid pressure is very low in the veins. Explain how blood gets back to the heart. Why is blood pressure higher in the aorta than in the inferior vena cava? a. The di...
High blood pressure, also known as hypertension, happens when it takes too much force to push your blood through your arteries, making your heart work too hard. More than 1.2 billion adults worldwide have high blood pressure, and almost half don't know they have the condition. ...
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...
arterial pressure- the pressure of the circulating blood on the arteries; "arterial pressure is the product of cardiac output and vascular resistance" venous pressure- the pressure exerted on the walls of the veins by the circulating blood
