Viscera refer to which anatomical structures?

• A. Muscles
• B. Bones
• C. Internal organs
• D. Skin

Answer: (C)

Viscera are the internal organs housed inside body cavities—the soft, internal structures such as the heart, lungs, liver, stomach, intestines, kidneys, and spleen. This term specifically targets the internal organs rather than the supporting or outer tissues. That’s why “internal organs” is the best fit. The other options describe tissues outside those organs: muscles are part of the musculoskeletal system, bones are the rigid framework of that system, and skin covers the outside of the body.
