Learn the interesting things about animal hearts

The human heart often beats 72 beats per minute, but at the same time, the animal heart like that of an American Macmot is hibernating, for example, only 5 beats, and the heart of a hummingbird is beating 1,260 times per minute throughout flight.

The human heart weighs about 0.3kg but the giraffes weigh up to 12kg because this species needs a healthy heart to pump blood through its long neck.

Unlike the human heart and the heart of most mammals and birds, the frog's heart has only three compartments, including two atria and one ventricle.The frog's heart is responsible for filtering the oxygen the body absorbs, moving it through the lungs to breathe, then pushing oxygen to the entire organ.

In addition, frogs not only get oxygen through the lungs but also from the skin so the frog's heart also works on its own principle, that is, blood cells go to the right atrium and out in the ventricles to the lungs and skin to get oxygen. .The cells absorb oxygen, then return to the left atrium, to the ventricles and bring oxygen to the body's organs.

Whales have a giant heart.The hearts of elephants are about the size of a small car and are several hundred kilograms.The heart of a whale has four compartments, which are responsible for pumping oxygen throughout the massive body like two buses of this species.According to science, the wall consists of the main arteries in the heart of the whale with the thickness equivalent to the length of an iPhone 6 Plus.

Molluscs have three hearts.Soft sea creatures including octopus, squid or starfish have three hearts.Two extra hearts help animals absorb blood, the main heart plays a role in regulating blood through arteries to feed the body.The three-hearted blood for the body of these soft bodies is green because the cells contain many copper elements.

The heart of the "scene" of cockroachesThe heart of cockroaches is not responsible for circulating blood throughout the body like the heart in other animals because it inhales through the air holes in the body instead of the lungs, so the blood does not need to carry oxygen from place to place.Cockroaches have a special blood circulation system that only flows around 12 to 13 main roads.Spinal sinuses, which are located on the top of the stem of the cockroach, help to transfer oxygen-absorbed blood to the chambers of the heart.

Earthworms use "fake" hearts.In fact, earthworms do not have hearts but they have five parts called "fake hearts" that surround the esophagus.The fake heart of earthworms is not supposed to pump blood but only works to contract blood vessels to help blood circulation take place.Worms also only absorb oxygen through its moist skin.

The heart of zebrafish can regenerate.When zebrafish is damaged by the heart, it can immediately recreate a new fruit instead.Research shows that zebrafish can regenerate 20% of damaged heart muscle in just two months.The heart of this fish has only one atrium and one ventricle and has two completely different structures than the human heart.
