The torso or trunk is an anatomical term for the central part or core of many animal bodies (including humans) from which extend the neck and limbs. The torso includes: the thoracic segment of the trunk, the abdominal segment of the trunk, and the perineum.

Major organs
Most critical organs are housed within the torso. In the upper chest, the heart and lungs are protected by the rib cage, and the abdomen contains most of the organs responsible for digestion: the stomach, which breaks down partially digested food via gastric acid; the liver, which respectively produces bile necessary for digestion; the large and small intestines, which extract nutrients from food; the anus, from which fecal wastes are egested; the rectum, which stores feces; the gallbladder, which stores and concentrates bile; the kidneys, which produce urine, the ureters, which pass it to the bladder for storage; and the urethra, which excretes urine and in a male passes sperm through the seminal vesicles. Finally, the pelvic region houses both the male and female reproductive organs.

Major muscle groups
The torso also harbours many of the main groups of muscles in the body, including the:
·pectoral muscles
·abdominal muscles
·lateral muscle
·epaxial muscles

Nerve supply
The organs, muscles, and other contents of the torso are supplied by nerves, which mainly originate as nerve roots from the thoracic and lumbar parts of the spinal cord. Some organs also receive a nerve supply from the vagus nerve. The sensation to the skin is provided by:
·Lateral cutaneous branches of torso|Lateral cutaneous branches
·Dorsal cutaneous branches
