That's Correct!
It's Wrong!
While running at full speed, a cheetah's heart can beat up to 170 times per minute. Cheetahs are the fastest land animals, capable of reaching speeds of up to 70 miles per hour (112 kilometers per hour) in short bursts. This incredible speed requires immense physical exertion, which is supported by a rapid heart rate that delivers oxygen and nutrients to the muscles at an accelerated pace. The cheetah's cardiovascular system is highly adapted to these intense sprints, but after a chase, the animal must rest to recover. Understanding the physiology of cheetahs highlights the specialized adaptations that enable their remarkable speed and hunting abilities.
