The blue whale has a giant Heart.
What animal has the biggest heart? The answer is :
The blue whale has the enormous Heart about its body size of any mammal.
The average blue whale heart is about the size of a small car and weighs nearly 400 pounds!
This means that the blue whale’s Heart constitutes about 2.3% of its total body weight.
In comparison, the average human Heart weighs just 10-12 ounces and constitutes only 0.06% of a person’s body weight.
The blue whale’s Heart is significant because it needs to pump blood through its colossal body.
A blue whale can rise to 100 feet in length and weigh 200 tons!
This is why the blue whale can hold more blood than any other land animal.
The average blue whale has a blood volume of around 5,000 liters!
That’s more than double the amount of blood found in an average human!
The Heart of a blue whale is about the same size as a small pony. The larger an animal is, the smaller its Heart relative to its body size.
African elephant’s Heart is so big.
The elephant’s Heart is around 27% of its body weight, making it the animal with the biggest heart.
However, when adjusted to body mass, the African elephant’s Heart is about five times smaller than an average human (about 80kg). This makes the human Heart the heaviest.
African elephant’s Heart is significant because it needs to pump around 5 liters of blood around its body. This is twice as much as a human’s Heart!
Despite its large size, the elephant’s Heart is very efficient at pumping blood around its body. However, its heart rate is only around 25-30 beats per minute.
On The Other Hand Human’s Heart
A human’s Heart is about 15% of its body weight, and it beats around 100,000 times a day. That’s a lot of work!
The Heart is one of the vital organs in the body. It pumps blood throughout the body, delivering oxygen and nutrients to all cells. Without a healthy heart, we wouldn’t be able to survive.
Although the human heart is about the size of a clenched fist, it is one of the strongest muscles in the body.
The average adult female has an even lower at 68 beats per minute.
The average adult male heartbeats 72 times per minute or about 100,000 times per day. So over a lifetime, that’s about 3 billion beats!
While a hippopotamus’ Heart is only about 2% of its weight, this is because the hippo’s Heart has to pump blood through much thicker tissue. A hippo’s Heart also beats about twice as fast as a human’s and can pump up to 25 gallons of blood per minute! That’s more than any other land animal!
The Biggest Heart in the animal kingdom belongs to the hippopotamus, which can weigh up to two tons and measure 12 feet in length. Thanks to their aggressive nature and sharp teeth, hippos are considered one of the most dangerous animals on Earth.
Nevertheless, they more than makeup for what they lack in pace in Heart. The hippopotamus’s enormous Heart has about as much capacity as a small car and can weigh as much as a newborn baby. And what’s even more impressive is that it can get more extensive when the creature inhales.
Despite their large size, hippopotamuses have a heart rate of just 25-40 beats per minute, much lower than the 60-90 beats per minute that are considered normal for most animals. Despite being the largest animal in history, the blue whale only has a heart that weighs 400 pounds and is just 0.5% of its total body weight.
The giraffe’s Heart
Despite being so tall, the giraffe only has a heart that weighs less than 10 pounds.
That is significantly smaller than other animals, such as the hippopotamus and the elephant. For example, the hippopotamus has a heart that weighs around 25 pounds, while the elephant’s Heart weighs in at approximately 88 pounds!
This enormous discrepancy is because of how these animals use their hearts. Giraffes don’t need to exert themselves as much as other animals, so their hearts don’t need to be as significant.
But, on the other hand, elephants and hippos have to work a lot harder to get around, and they need that bigger Heart to support them.
