[Comparison of the dog's vena jugularis and the human vena saphena magna].

The present contribution compares the histologic and mechanic qualities of the vena saphena magna in man with the dog's vena jugularis. Both venae have a similar histologic structure and an analogous enzymatic equipment. The dog's vena jugularis has a smaller mechanic resistance, however, it is fast enough to resist the artery pressure. The dog's vena jugularis is therefore suitable for experiments with venae transplants which are reproducible in the clinical application.
