No human organ continues to grow after death. The misconception that hair and fingernails grow after death stems from the fact that the surrounding skin and tissues dehydrate and retract post-mortem, making the hair and nails appear longer. This is explicitly stated in one reference: "For thousands of years, people thought that the dead's hair and fingernails kept growing after death because that's what it looked like to the naked eye. But it's not that the hair and nails are growing, it's that the rest of your body is shrinking."
While the liver possesses a remarkable capacity for regeneration during life, this process ceases upon death. Several references mention the liver's regenerative ability: "The liver has a unique capacity among organs to regenerate itself after damage. A liver can regrow to a normal size even after up to 90% of it..." However, this regeneration is a living process; it does not continue post-mortem.
Similarly, cartilage in the nose and ears continues to grow very slowly throughout life, but this growth stops after death. One source notes: "But cartilage - that's the plastic-like stuff in ears and noses -... ".
Therefore, the premise of the question requires clarification. No organ continues to grow in the traditional sense of cell division and expansion after death. The appearance of growth is an illusion caused by post-mortem dehydration and tissue shrinkage.
