Основное значение сердечно-сосудист

Основное значение сердечно-сосудистой системы состоит в снабжении кровью органов и тканей. Кровь непрерывно движется по сосудам, что дает ей возможность выполнять все жизненно важные функции. К системе кровообращения относятся сердце и сосуды — кровеносные и лимфатические.

Сердце представляет собой биологический насос, благодаря работе которого кровь движется по замкнутой системе сосудов. Каждую минуту сердце перекачивает в кровеносную систему около 6 л крови, в сутки — свыше 8 тыс. л, в течение жизни (при средней продолжитель­ности — 70 лет) — почти 175 млн. л крови.
