Under normal circumstances, a woman's heart is located in the lower center of the left chest. For adult women of normal height and weight, the projection of the heart on the skin mainly includes the following parts: the upper left point is at the outer edge of the second left rib cartilage, about 1.2 cm away from the left edge of the scapula; the upper right point is at the upper edge of the third right rib, about 1 cm away from the right edge of the scapula; the lower right point is at the right sixth sternal costal joint; the lower left point is at the intersection of the fifth left intercostal space and the left clavicle midline, and the lower left point is the position of the atrium. Under normal circumstances, the human heart is roughly the same size as one's fist, roughly shaped like an inverted peach that is wide at the top and pointed at the bottom, with the atrium located more toward the left front and the heart more toward the right back. If a gene mutation occurs, dextrocardia may also occur. The heart is located in the middle mediastinum of the chest cavity and is surrounded by the pericardium. About 2/3 is on the left side of the center line of the human body, and 1/3 is on the right side of the center line. Directly below is the central tendon of the diaphragm, with the lungs, pleural thickening and pleural cavity on both sides, the esophagus, sympathetic nerves and thoracic aorta behind, and most of the front is covered by the lungs and pleural thickening. Only a small triangle area in the front and lower part is not covered, which is in direct contact with the lower half of the scapula and the fourth and fifth costal cartilages on the left. In clinical medicine, intracardiac injection is usually performed close to the fourth intercostal space on the left edge of the scapula, without injuring the pleural thickening and lungs. Under normal circumstances, the heart of an adult is located in the chest cavity, with two-thirds located to the left of the midline and one-third located to the right of the midline. The size is about the size of your fist. There is one atrium (located approximately 2-3 cm below the left nipple), one heart, with three sides, three edges, etc. The main function of the heart is to participate in the blood circulation system, and it can also secrete some hormones. In special cases, such as the rare dextrocardia, the heart position is mirror-imaged to the center line of the human body compared to that of normal people. The heart is in the chest cavity, above the diaphragm, between the two lungs, slightly to the left, on the side of the left breast, and is the same size as your fist. The heart is an important internal organ that promotes blood flow and transports blood nutrients to every important organ in the body. Therefore, we must pay attention to good health in normal times and avoid fatigue and overwork. If you have pain or discomfort in the precordial area, be sure to rest. If the symptoms still cannot be relieved after rest, you need to go to the cardiology department of a regular hospital for examination and do an electrocardiogram to see if the heart is ischemic. And in daily life, we must prevent colds. For example, a mild fever and cold may affect the heart over time if we do not pay attention to it. Viral infection may cause damage to the heart lining. |
