The heart is a muscular organ that is a part of the cardiovascular system. The heart controls the flow of blood throughout the body through contraction and dilation. The heart uses arteries and veins to direct the flow and movement of blood throughout the body....

How do arteries and veins differ in the direction of blood flow? Which is the first and largest blood vessel that carries oxygenated blood to the systemic circuit? (a) Aorta (b) superior vena cava (c) coronary arteries (d) pulmonary artery (e) carotid artery. ...
Arteries and veins are structurally different and have long been functionally defined by the direction of blood flow that they carry. However, a growing body of evidence indicates that the identity of the endothelial cells that line these vessels is determined in the developing embryo, before circul...
Viscous fluid flow follows the differential equation of viscous fluid motion. If the flow is only subject to gravity and has an incompressible and steady-state flow, the differential equation can be integrated into Eq.1to depict the hydraulic loss in the flow direction of a 1D round pipe [49...
In performing all calculations, 80 terms in the direction of x and 120 terms in the direction of y were used in the series solution for each layer. The thermophysical characteristics of the tissue are also according to Table 1. The laser specification is Conclusion The blood vessel was ...

Fig: Structure of Blood Vessels Valves 1. Valves arepresent in veinsexcept for pulmonary vein and not in arteries except pulmonary artery and aorta in which valve is there. 2. It prevents the backflow of blood in veins, i.e., ensures the flow of blood in one direction. ...
2. Mathematical Formulation Consider an axially symmetric, laminar, pulsatile, and fully developed flow of blood in the axial direction z through a circular tapered artery with an axisymmetric mild stenosis. The artery is assumed to be too long so that the entrance and end effects can be ...
arteries. Our findings indicate that NOTCH1 signaling responds to laminar flow and that this response scales with the magnitude of shear stress. Furthermore, we show that NOTCH1 protein is able to sense laminar flow by rapidly locating to the downstream pole relative to the flow direction. Our...
