QuestionAnswer
Jelaskan dgn ringkas!! Bagaimana impuls elektrik disebar melalui jantung （︶^︶） a) Jantung mempunyai otot kardium yg bersilang & bersambungan antara satu sama lain b)Susunan ini membenarkan impuls elektrik untuk disebar dgn cepat, merangsang sel otot kard.. utk mengecut [ seragam & serentak ]
Otot kardium bersifat miogenik, WTF does that mean??🌭 Jantung mengecut & mengendur tanpa perlu menerima isyarat impuls daripada sistem saraf
Apakah itu perentak jantung?? Sekumpulan sel otot jantung khusus yang memulakan kadar pengecutan jantung & terletak pada dinding atrium kanan
Terangkan secara ringkas Pengepaman jantung..😷👻 1) Nodus sinoatrium menjana impuls elektrik 2) IMpuls elektrik merebak dgn cepat dalam kedua2 dinding atrium-- dinding atrium mengecut-- serentak 3) Oleh itu, darah dipam ke dalam ventrikel-- ventrikel mengecut 4) sambungan di buku teks :}
Ketika pengepaman jantung, bunyi lub-dub didengari, Apakah penyebabnya?? Bunyi Lub dihasilkan apabila injap trikuspid dan bikuspid tertutup Bunyi Dub dihasilkan apabila injap sabit tertutup
Mengapakah Pengepaman jantung X cukup untuk meneruskan pengaliran darah melalui vena untuk kembali ke jantung?? Pengaliran darah terpaksa melawan menentang daya tarikan graviti, Kehadiran injap di dalam vena memastikan pengaliran darah adalah 1 hala
Elaborate!! Pengecutan otot rangka di sekeliling vena bagi membantu pengaliran darah.. 😚 1)Otot licin mengecut yang terdapat pada dinding venul dan vena 2)Otot rangka juga mengecut di sekeliling vena yang menekan & mencerut vena lalu menyebabkan injap terbuka 3)Injap kemudian tertutup bagi menghalang darah mengalir balik ke arah kaki
