In der Leber (Terminologia histologica. Hepar, englisch: liver) finden sich relativ weite Kapillaren, die Sinusoide mit gefensterten Endothelzellen ohne Verschlußhäutchen (Diaphragmata). Zwischen den eigentlichen Leberzellen (Hepatocyten) kommen erweiterte
Zellzwischenräume vor, sogenannte Gallenkanälchen (Terminologia histologica: Canaliculi biliferi; englisch: Bile canaliculi), die kein eigenes Endothel besitzen und in die Herring Kanälchen am Rand von Leberläppchen münden. Vitamin A und Fett werden in den ITO-Zellen gespeichert, die stets unter dem dünnen Sinusoidendothel liegen. Die von Kupffer-Zellen sind große Freßzellen (Makrophagen), die sich im Lumen der Sinusoide aufhalten und mit einigen Füßchen im Disse-Raum verankert sind.
Der Disse-Raum ist der Raum zwischen dem Hepatocyten und den die Sinusoide auskleidenden sehr platten weit gefensterten Endothelzellen. Hier finden sich aus Kollagen Typ III bestehende retikuläre Fasern und ggf. ITO-Zellen.
Leberzellen können gelegentlich 2 Kerne aufweisen und enthalten viele Peroxisomen sowie alpha-Glykogengranula, reichlich glattes und rauhes endoplasmatisches Retikulum sowie viele dunkle Mitochondrien vom Crista-Typ.
