Solid organs include which of the following?

• A. Hollow organs
• B. Muscle tissue
• C. Solid organs
• D. Glandular structures

Answer: (C)

Distinguishing solid organs from hollow ones depends on tissue structure and the presence of a lumen. Solid organs are made up of dense parenchymal tissue with little or no internal cavity, so they feel and look solid. Classic examples include the liver, spleen, pancreas, and kidneys. In contrast, hollow organs have a central cavity (lumen) that can contain contents and vary in size. The option that names the category itself—solid organs—best fits this concept because it directly identifies the group defined by having solid parenchymal tissue rather than a lumen. The other choices describe tissue types or opposite or unrelated categories (hollow organs, muscle tissue, glandular structures) and do not capture the defining characteristic used to classify solid organs in this context.
