Zusammenfassung und Implikationen,en proceed to solve the equations, predict results, and validate the predictions with animal experiments. Such a program has been carried out by Schmid-Schönbein and his associates for blood flow in skeletal muscle. We present their main results here.

Impugn

Zusammenfassung und Implikationen, blood flow through the heart. The most important feature of the systemic veins is, therefore, their compliance. A compliant structure runs the danger of collapsing; the problem with the vein is that it is often collapsed.

Theoretisches Fazit und Fragestellungen, of mass means that whatever flows in must flow out. If flow is confined to blood vessels, then we obtain a rule similar to Kirchhoff’s law of electric circuits: At any junction the summation of current flowing into a junction must be equal to the sum of the currents flowing out of that junction. In

galley

Zusammenfassung und Implikationen, In humans, the aorta originates in the left ventricle at the aortic valve, and almost immediately curves about 180°, branching off to the head and upper limbs. It then pursues a fairly straight course downward through the diaphragm to the abdomen and legs. The aortic arch is tapered, curved, and tw

Zusammenfassung und Implikationen,tia forces, and forces of tissue and muscle. Only in the boundary layer are the viscous friction forces important. The boundary layer thickness grows with increasing distance from the entry section, and in a long tube the boundary layer on the wall eventually becomes so thick as to fill the entire t
