Quizplus · Accepted Answer

Systole is the phase of the heartbeat when the heart muscle contracts and pumps blood out of the chambers into the arteries. This is the working phase of the heart where blood is being actively circulated throughout the body. The other options, pulse and heart rate, are measurements of the heart's activity rather than specific phases, while diastole is the phase when the heart is relaxed and filling with blood.
