The chest and the abdomen make up the torso on the human body. Another name for the torso is the trunk. Basically, it is the body without the head or limbs.
Many of the body's major organs are found in the torso. The chest contains the heart and lungs, while the abdomen houses the digestive system, including the stomach, small intestines, large intestines, liver and pancreas. The torso also encases the spleen, kidneys, bladder and reproductive system. Numerous major blood vessels, such as the aorta and the inferior vena cava, are in this major section of the body, as well as the spine and a number of important muscles and bones.
