Blood Flow in Coronary Vessels,ajor coronary arteries (Fig. 6.1), a right and left, arise respectively from the right anterior and left anterior aortic sinuses of Valsalva. The left main coronary artery in adult humans is about 4–5 mm in diameter, and the mean length of this artery is 1.3 cm. The right coronary artery as its orig

It is well-known that the presence of a stenosis within a large artery gives rise to a region of turbulent flow downstream of the obstruction (Giddens et al. 1976). When the flow is highly disturbed or turbulent, the pressure loss (pressure gradient) across the stenosis is

However, apart from hypoxia, chemical control does not play an important role under physiological circumstances. The main factors which control the pulmonary flow seem to be mechanical properties of the pulmonary artery and the pulmonary vascular beds.

Stenosis: Theoretical Background,Although the etiologies of stenoses appearing in various parts of the cardiovascular system may differ, their effects on blood flow can be summed up in a single term, pressure loss.
