The liver is a solid organ.

The liver is a solid organ.

• A. False
• B. True
• C. Not Always Solid
• D. Partially

Answer: (B)

In anatomy, solid organs are those whose parenchyma forms a dense tissue mass with no single, continuous hollow cavity running through the organ. The liver fits that description: its tissue is made of hepatocytes arranged in lobules with vascular sinusoids and bile canaliculi interspersed, but these are microscopic channels within the tissue, not a large central lumen. There isn’t a continuous hollow space that spans the whole organ, so the liver is classified as a solid organ. While it contains blood vessels and ducts, these do not make the organ hollow; they are part of the tissue architecture. Some might wonder about ducts or cavities, but they do not redefine the organ as hollow.
