Which tissue type includes bone marrow as an example?

• A. Solid tissue
• B. Fluid tissue
• C. Epithelial tissue
• D. Muscle tissue

Answer: (B)

Tissue types are grouped by their fundamental nature: solid, fluid, epithelial, or muscle. Bone marrow is a soft, gel-like tissue inside bones where blood cells develop and mature, providing a site rich in cells and fluid components rather than a rigid, structured framework. This functional and physical characteristic aligns it with fluid tissue, which includes tissues associated with circulating elements like blood. The other categories describe tissues that form surfaces (epithelial), contract to move (muscle), or provide rigid structure (solid tissues), which doesn’t fit bone marrow as well.
