Sounds of Hummingbird heartbeats as compared to humans

Описание: In humans normal heart rate ranges from 60-100 beats per minute. One human heartbeat is composed of two sounds. One sound is produced by the opening and closing of AV vales, these valves pump the blood to the lower muscular chambers of the heart called ventricles. The second sound is produced by the set of valves that pump the blood to the lungs and body parts. This is how the human heart beats sound. The fastest recorded heartbeat in humans is 480 in a patient with tachyarrhythmia.

Hummingbirds are an amazing group of birds. They are found in both North and South Americas. The smallest Hummingbird is the bee hummingbird that is found in Cuba. Bee hummingbird weighs 2.8-5.6 grams as much as a penny.

Hummingbirds feed on the plant nectar that is mostly sugar. Hummingbirds’ metabolism is 77 times faster than humans. They supplement the nutrients in their diet and eat some insects on occasion. Hummingbirds can flap their wings from 53- 80 times per second.

To maintain fast metabolism hummingbirds, pump huge amounts of blood to the body cells. The hummingbirds have the fastest heart rates in the birds. The heart rate ranges from 1000-1200 beats per minute in most hummingbirds. The reason hummingbirds can maintain such high heartbeat without getting cardiac arrest is that their heart muscle cells have many times more mitochondria than humans.
