End systolic volume (ESV) â The amount of blood still in the. ventricles after the contraction is complete. End diastolic volume (EDV) â The amount of blood in the. ventricles after they have filled but prior to the beginning of. the contraction.
This is the fastest form of travel for most snakes, but rattlesnakes donât engage in this style of locomotion often. Rattlesnake speeds have not been specifically measured, but they likely travel at about 2 to 3 miles per hour in very short bursts. In comparison, the fastest humans can run up to 28 miles per hour.
Cheetahs, of course, are built to run faster than humans, regularly clocking speeds of up to around 60 miles per hour (96.5 kilometers per hour). During a photo shoot with National Geographic Magazine, a cheetah from the Cincinnati Zoo named Sarah covered 100 meters and clocked a peak speed of 61 mph (98 kph).heetahs, of course, are built to run faster than humans, regularly clocking speeds of up to around 60 miles per hour (96.5 kilometers per hour).
