APAKAH MAKSUD CHORIOALLANTOIS dalam CORSICA?
Membran Chorioallantoic
Membran chorioallantoic - juga dikenali sebagai chorioallantois atau disingkat CAM - adalah membran vaskular yang terdapat dalam telur beberapa amniotes, seperti burung dan reptilia. Ia dibentuk oleh gabungan lapisan mesodermal dua struktur pembangunan: allantois dan chorion. Dalam mamalia, struktur ini membentuk plasenta. Tiga lapisan berbeza menyusun membran chorioallantoic; ini dipanggil epitelium chorionic, mesenchyme dan epitel allantoic. Kapilari darah dan sinus didapati di antara sel-sel epitelium lapisan chorionic, membenarkan hubungan rapat dengan udara yang terdapat pada pori-pori membran sel telur. Hasilnya, membran chorioallantoic membolehkan pertukaran gas, seperti oksigen, untuk mengembangkan embrio. Semasa perkembangan embrio burung, membran chorioallantoic juga memainkan peranan penting dalam pembentukan tulang dengan mengangkut kalsium ke dalam embrio dari kulit telur. Membran Chorioalloantoic dari telur ayam berkembang secara rutin digunakan dalam penyelidikan biologi dan biologi untuk menyiasat perkembangan, angiogenesis, tumor, dan menyebarkan dan menyiasat virus atau helminths.

Development of Cardiovascular Systems: Molecules to Organisms
Before the chorioallantois becomes functional, the embryo uses the area
vasculosa of the yolk sac for gas exchange (from about day 3 to day 6 in chickens

increases in ...

In other words, the chorioallantois of the egg acts as a lung. The chorioallantois
also has other functions. The embryo obtains 80 per cent of the calcium that it
