The organs under the chest are generally divided into the left and the right chest, and most of the organs under the left as well as the right chest are different. For the left chest, below the left chest are the lungs, below the front is the heart, below the left rib cage is the stomach, behind the stomach is the left kidney, and half of the pancreas, and further down is the left colon, including half of the transverse colon, half of the descending colon, and then the spleen and the jejunum in the left upper abdomen. If there is pain in the left side of the chest, it needs to be clarified whether there is some disease in these internal organs, especially to rule out some heart disease. Below the right chest is mainly the liver and gallbladder. If there is pain in this area, it is usually due to hepatitis or cholecystitis, and usually may be accompanied by jaundice. The right chest is mainly the right lung, and the lower part is the liver and gallbladder, which is also under the ribs. At the same time, you can do a chest X-ray, liver and gallbladder ultrasound, and liver function test, and if accompanied by coughing and coughing up phlegm, it is considered to be a greater lung disease.
