Giraffes have a very strong heart that pumps blood twice as hard as a cow's heart in order to get blood to its brain. The giraffe's long neck presents a challenge in terms of blood flow, as the heart has to work extra hard to pump blood all the way up the neck and into the brain. In order to achieve this, the giraffe's heart has a thicker left ventricle wall than other mammals of a similar size, which allows it to pump blood more forcefully. Additionally, giraffes have a very high blood pressure, which helps to get blood to the brain more efficiently.
