Definition : In the study of anatomy, viscera (singular viscus) refers to the internal organs of the abdominal, thoracic, and pelvic cavities.

The abdominal organs may be classified as solid organs or hollow organs.

The solid organs are the liver, pancreas, spleen, kidneys, and adrenal glands.

The hollow organs of the abdomen are the stomach, intestines, gallbladder, bladder, and rectum. In the thoracic cavity the heart is a hollow, muscular organ.

The number of organs in any organism depends on the definition used. By one widely adopted definition, 79 organs have been identified in the human body.
