The changes of the variables with time are shown in Figure 3/5/1. It will be seen that the changes of the variables show a charac- teristic pattern, for the blood-flow through leg and gut falls more than that through the inferior vena cava, and this difference is characteristic of the body's reaction to haemorrhage.
