Heart rate: is the number of times your heart beats in a minute. This depends on certain factors, for example: if you are a young and healthy adult, your heart rate should be normal (for example 72 beats per minute). However, if you are a person under high levels of stress (but are otherwise healthy), your heart rate may become higher (for example, 94 bpm or higher).
Because a heart pumps blood just like a pump would pump water.
