Answer 2

Elephants Heart

Answer 3

It just so happens that the heart of the African bull elephant can weigh up to 28 kg, which is a size normal for such a large animal. Despite its large size, the circulatory system of the elephant is quite unexceptional. In keeping with the size of the animal, elephant hemoglobin has a higher oxygen affinity than that of other mammals. A peculiarity exists with the ventricles of the elephant. The ventricles are separated at their apex. Also, there are paired venae cavae instead of the usual single vein. These peculiarities are found in other penungulates and are probably primitive.

Due to their enormous size, arteries are supported by ridges of elastic fibers or muscles cells. The veins are supported by having proportionately thicker walls than other mammals. The blood vessels of the elephant can achieve lengths of up to 350 cm, which require a high blood pressure in order to prevent their collapse if they had thin walls.

Something else that was an interesting fact is that the human heart beats at the rate of 70 per minute, The mouse beats 500 times a minute and the elephant beats a mere 28 times a minute.

Not sure if you are interested but, the elephant produces 110 kg/day of fecal matter and its urinary Output is 50 litres/day.
