The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:
<span>P = ρ*g*h
</span>P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= <span>20 580 pascals= 20.58 kpa</span>
