Discover the Top 7 Animals With the Highest Blood Pressure

they lose a third of their body weight. However unlike humans bears dont get diabetes or suffer other poor health effects from putting on all that extra weight. Scientists have discovered that bears can control their resistance to insulin by turning it off or on. Someday researchers may find the key to helping humans with diabetes by learning more about the heart health of bears. 
Birds
Birds need high blood pressure to push blood through their bodies very quickly to give them the strength and energy to fly.

To be able to fly birds need large hearts to meet their oxygen demands. The heart of a bird is 50 to 100 larger than a mammal of a similar size. Furthermore birds need to be able to pump blood to their brain wings and flight muscles. Because of this a birds blood pressure can range from 108250 mm Hg depending on the species. Below are some examples of various blood pressure readings in birds. 
Great Horned Owls 232 mm HgCanary 220 mm HgRedtailed hawks 220 mm HgCanada Geese 177 mm HgWild turkey 193 mm HgStarling 180 mm HgDuck 162 mm Hg
Birds are able to sustain high blood pressure because they have stiffer arteries that improve blood flow and faster heart rates. For example a hummingbirds heart can beat 1260 times per minute. 
Elephants
An elephants large heart can pump blood at a rate of 180 mm Hg.
Elephants weigh from 6500 pounds to 12000 pounds. Unsurprisingly they also have large hearts. An African elephants heart is one of the largest among mammals that live on land. Furthermore this massive heart must pump blood through veins that can reach 10 feet in length. To do this an elephants blood pressure must be high otherwise the veins would collapse. Elephants have a systolic blood pressure of 180 mm Hg. However to counter this high blood pressure elephants have a low resting heart rate. An elephants heart at rest beats about 30 times per minute compared to a human heart at 60 beats per minute. 
Interestingly when a human lies down to rest their blood pressure goes down. However its the opposite for elephants. When elephants lie down the weight of their body reduces their lung capacity. This means their heart has to beat faster and blood pressure must increase to get oxygen throughout their body.
Horses
A horse can lower its heart rate rapidly after
