Detak Jantung Manusia Bisa Menggerakkan Truk Sejauh 32 km Pada dasarnya jantung manusia sudah mulai bekerja ketika masih berada di dalam rahim. Sebuah penggerak kecil di bagian belakang kanan atrium yang sering disebutsino-atrial (SA) berguna sebagai alat pacu jantung.
Bagian ini berperan mengirimkan impuls listrik untuk membuat jantung berdetak dalam internal normal. Menurut penelitian, setiap kali impuls tersebut dikirimkan tenaga yang bisa dihasilkan kurang lebih akan setara dengan 1-5 watt.
Jika hal tersebut dikalkulasikan maka energi tersebut akan mampu untuk menggerakkan truk sejauh 32 km setiap harinya. Hal ini setara dengan mengendarai truk tersebut ke bulan dan kembali lagi, jika dihitung dari detak jantung kita selama kita hidup sampai umur 70 tahun.
