Anatomie en fysiologie van het spijsverteringskanaal
De maag
Maag – ventriculus – gaster
Functies:
• Tijdelijke opslag -> voedsel
• Kneding -> voedselbrij mengen
• Chemische afbraak
• Doden van ziektekiemen -> door de lage pH van de zuren
• Productie van intrinsieke factor -> zorgt voor opname vitamine B12
Activiteiten van de maag
1. Cefalische fase
• Maagsapafgifte -> sap wordt gevormd als je eten ziet of ruikt
2. Gastrische fase (voedsel beland in de maag)
• Knedende bewegingen
• Maagsapafgifte
• pH daalt sterk -> om eiwitten goed af te breken en ziektekiemen te doden
3. Intestinale fase (voedselbrij gaat naar de twaalfvingerige darm)
• Eerste chymus gaat door de pylorus
• Activiteit van de maag neemt af
• Kleine beetjes worden doorgelaten -> de kleine beetjes van de voedselbrij worden
geneutraliseerd met behulp van spijsverteringssappen van de alvleesklier
