The giraffe holds the record for having the highest blood pressure of any mammal. Its blood pressure can reach up to 280/180 mm Hg, which is about twice that of humans (120/80 mm Hg). This extremely high blood pressure is necessary for the giraffe to pump blood up its long neck, ensuring that its brain receives enough oxygen and nutrients despite the challenges posed by gravity.
This adaptation, along with a powerful heart and specialized cardiovascular system, allows the giraffe to maintain efficient circulation even with its towering height.
The giraffe holds the record for having the highest blood pressure of any mammal. Their blood pressure can reach up to 300/180 mm Hg, significantly higher than the typical human blood pressure of 120/80 mm Hg. This high blood pressure is essential for giraffes to pump blood all the way up their long necks to their brains, overcoming the force of gravity. Their unique cardiovascular adaptations, including a powerful heart and specialized blood vessels, help them manage this extreme pressure without suffering the harmful effects that would affect other mammals.
