What does the term viscera refer to?

The term "viscera" specifically refers to the internal organs of the body, particularly those located within the abdominal cavity. This includes organs such as the stomach, liver, intestines, and kidneys, which are critical for various bodily functions, including digestion, waste management, and metabolism. Understanding this terminology is essential in veterinary medicine, as it helps professionals communicate accurately about the anatomy and health of animals.

The other options relate to different aspects of anatomy: the joints of the skeletal system pertain to the connections between bones, muscle tissues refer to the contractile tissues responsible for movement, and layers of skin involve the protective outer covering of the body. However, none of these options convey the specific meaning of "viscera," which is exclusively associated with internal organs.
