Fig. 2. Profile of giraffe cranial pressures. Solid lines show known pressures using published data (Mitchell and Skinner, 1993; Hargens et al., 1987). Broken lines show pressures generated by the model, and are given in more detail in Table 2. Note that the model can replicate known giraffe jugular pressures, can replicate separately mean arterial pressure and mean cranial pressure, but cannot replicate all typical giraffe carotid and jugular pressures simultaneously.
