Сердце человека сжимается с первого момента жизни до последнего. Сокращения сердца перекачивают кровь через артерии во все части тела. Ученые определили, что общий вес крови, перекачиваемой сердцем ежедневно, составляет около десяти тонн.
Частота сердечных сокращений регулируется двумя группами нервных волокон. Она различается у разных людей и в разном возрасте.
Физиологи определили, что у взрослого человека сердце составляет от 60 до 72 ударов в минуту. У детей частота сердцебиения значительно выше. Исследовательская работа многих ученых Установить, что частота сердцебиения увеличивается в зависимости от разных эмоций.
Каждое биение сердца сопровождается периодом отдыха для сердечной мышцы. Каждая волна сокращения и последующий за ней период покоя составляют сердечный цикл.
Исследовательская работа дала физиологам возможность выяснить, что сердечная мышца работает или сокращается примерно в одной трети времени жизни человека. Период покоя короче во время большей физической нагрузки и длиннее, когда тело находится в состоянии покоя.
Каждый сердечный цикл состоит из трех фаз: физиологи назвали первую фазу короткого сокращения обеих предсердий-систолу предсердий. Они назвали вторую фазу более длительным сокращением обоих желудочков-желудочковой систолы. Период покоя сердечной мышцы называется диастол.
