zwischen diesen Körperhöhlen ermöglicht - unter anderem der Aorta, der unteren Hohlvene und der Speiseröhre. Dem Zwerchfell direkt anliegend ist ein Abschnitt des Brustfells, der als Zwerchfellteil des Brustfells bezeichnet wird. In dieser Abbildung ist das Brustfell beidseits entfernt, sodass die darunter liegende linke und rechte Sehnenplatte des Zwerchfells sichtbar sind. Der Herzbeutel liegt auch direkt auf dem Zwerchfell und umgibt das Herz. Die Muskelfasern des Diaphragma entspringen der Sehnenplatte des Zwerchfells und setzen peripher an den Grenzen der unteren Thoraxapertur (Wirbel Th12, 10.-11. Rippe, Knorpel der 7.-10. Rippe und Schwertfortsatz des Brustbeins) an. Aufgrund der kuppelförmigen Struktur des Zwerchfells entstehen am Rand einige pleurale Aussackungen.
