Script: Jantung lazimnya berdegup 113 kali seminit.

Perhatikan jantung bertukar warna apabila darah keluar masuk kebuk semasa ia berdegup.

Jantung akan berdegup lebih kurang 54 juta kali sebelum kelahiran dan melebihi 3.2 bilion kali sepanjang jangka hayat 80-tahun.

All ages referenced to fertilization, not last menstrual period.
