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-=-...

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
ovarian or cervical arteries as well. Because of the technical difficulties in the measurement of uterine blood flow, including the necessity to measure flowof each uterine artery, studies of the velocity waveform in the uterine artery are likely to prove more clinically useful in the immediate ...
The effective diameter, calculated from the synchronized integrals of the blood flow velocity and the diameter curves, was significantly greater (p in the range 0.0001 to 0.0016) than the mean diameter. The difference tended to decrease with advancing gestational age and was more pronounced in the...
It gradually blends with the coverings of the superior vena cava and the pulmonary (lung) arteries and veins leading to and from the heart. (The space between the lungs, the mediastinum, is bordered by the mediastinal pleura, a continuation of the membrane lining the chest. The superior vena...
Arteries are the large, muscular vessels that carry oxygenated blood away from the heart into the tissues. Capillaries are tiny blood vessels that are the site of gas and nutrient exchange between the blood and the surrounding tissues. Veins carry deoxygenated blood back to the heart. What is ...
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. ...
Arteriovenous anastomoses or communications between arteries and veins larger in calibre than capillaries have been reported by anatomists in a number of tissues [1]. Their function has been observed by microscopic observations of the microcirculation of living tissues [2]. In order to evaluate the ...
Blood Flow in Arteries Abstract The larger systemic arteries, shown in Fig. 3.1:1, conduct the blood from the heart to the peripheral organs. Their dimensions are given in Table 3.1:1. In man, the aorta originates in the left ventricle at the aortic valve, and almost immediately curves ...
