Several factors increase cardiac … WebIncreased cardiac output is the main haemodynamic factor, mediated by lower afterload, increased preload, and positive inotropic and chronotropic effects. Decreased afterload is due to vasodilatation and reduced vascular resistance as a consequence of lower blood viscosity, hypoxia-induced vasodilatation, and enhanced nitric oxide activity.
WebThe pressure of the blood flow in the body is produced by the hydrostatic pressure of the fluid (blood) against the walls of the blood vessels. Fluid will move from areas of high to low hydrostatic pressures.
