Does endoscopy go into small intestine?

Qual a absorção do duodeno e do jejuno?
Quanto a absorção, carboidratos e proteínas são absorvidos no duodeno e no jejuno, respectivamente. O jejuno também absorve a maior parte das gorduras. As funções do íleo envolvem absorção de vitamina B12, sais biliares e toda a digestão dos produtos que não foram absorvidos no duodeno e no jejuno.
Qual a função do duodeno no intestino?
As células epiteliais do intestino delgado secretam enzimas que digerem o quimo em partículas menores, tornando-as passíveis de absorção. O duodeno tem ainda a função de misturar a comida com a bile e com as enzimas pancreáticas para continuar a digestão de carboidratos, gorduras e proteínas.
Qual é a parte superior do duodeno?
A parte superior (bulbo duodenal ou ampola) é a única parte intraperitoneal, já que o ligamento hepatoduodenal e o omento maior estão ligados a ela. A parte descendente do duodeno tem uma abertura chamada de papila duodenal maior (ampola de Vater).
