WebApr 1, 2002 · Thus, this shunt may be important for myocardial oxygenation. This hypothesis predicts that the L-R shunt will occur when the cardiac workload is elevated, since myocardial oxygen demands are greater when the heart is working hard than when the heart is at rest (Bing et al., 1972; Farrell et al., 1994, but see Jackson et al., 1995). WebAug 15, 2014 · A net cardiac shunt of various magnitudes in anuran amphibians has been quantified with measurements of and and is dependent upon metabolic state or other conditions ...

Net cardiac shunts in anuran amphibians: physiology or physics?
Webfeedback structures should be used (series-shunt, series-series, shunt-shunt, or shunt-series) – Voltage amplifier – voltage-controlled voltage source • Requires high input impedance, low output impedance • Use series-shunt feedback (voltage-voltage feedback) – Current amplifier – current-controlled current source The pentose phosphate pathway (also called the phosphogluconate pathway and the hexose monophosphate shunt and the HMP Shunt) is a metabolic pathway parallel to glycolysis. It generates NADPH and pentoses (5-carbon sugars) as well as ribose 5-phosphate, a precursor for the synthesis of nucleotides. While the pentose phosphate pathway does involve oxidation of glucose, its primary r… WebVascular shunt mechanism. Redistribution of blood flow during exercise. When at rest the muscles receive a relatively small amount of blood as they are not active. During exercise the distribution of blood changes. A great deal more blood is required by the muscles for movement. The diagrams show the changes. diy miniature house uk
