The giraffe is the organism which has systolic pressure among the other options.
The giraffe has one of the highest blood pressures of any mammal. It reaches pressures of up to 280/180 mm Hg, which is twice that found in humans (120/80 mmHg).
In their heads, a giraffe’s blood pressure remains about equal to a human’s. And they maintain that lower pressure in their heads whether they are chomping leaves from the limbs of tall trees or sipping water at ground level.
A giraffe’s large neck veins contain a complex system of valves that stops the blood from flowing backwards and pooling when it dips its head, which can be a full 20 feet differential from upright in a full-grown giraffe.
