The relationship between stomach and heart

In fact, all organs and tissues in the human body are connected. If one organ has a problem, it will affect other organs and tissues. In particular, the relationship between the stomach and the heart is very important. They are the two most important organs in the body. If there is a problem with the gastrointestinal tract, it will cause some problems with the heart, which will lead to symptoms such as arrhythmia.

The heart is the most important organ in the vertebrate body. Its main function is to provide pressure for blood flow and circulate blood to all parts of the body. The human heart is located in the lower left middle of the chest cavity. It is about the size of a fist and weighs about 250 grams. Women's hearts are generally smaller and lighter than men's. The human heart is shaped like a peach and is located above the diaphragm, between the two lungs and slightly to the left.

The heart is composed of myocardium and four chambers: left atrium, left ventricle, right atrium, and right ventricle.

The left and right atria and the left and right ventricles are separated by septa, so they are not connected to each other. There are valves (atrioventricular valves) between the atria and ventricles. These valves prevent blood from flowing from the atria to the ventricles and not flowing back.

The function of the heart is to promote blood flow, provide sufficient blood flow to organs and tissues to supply oxygen and various nutrients, and take away the end products of metabolism (such as carbon dioxide, inorganic salts, urea and uric acid, etc.) so that cells maintain normal metabolism and function.

The heart is located in the chest cavity, above the diaphragm, between the two lungs, and about two-thirds to the left of the midline. The heart is like an inverted, slightly flattened cone at the front and back, like a peach. The apex of the heart is blunt and round, facing the left front and lower side, close to the anterior chest wall. Its surface projection is 1-2 cm inside the midclavicular line in the fifth intercostal space of the left anterior chest wall, so the apex beat can be seen or felt here. The base of the heart is wide, with large blood vessels entering and exiting it, heading towards the upper right posterior side, adjacent to the esophagus and other organs in the posterior mediastinum.

1. Apex of the heart: facing the left front and lower side, located in the fifth intercostal space on the left side, 1 to 2 cm inside the midclavicular line.

Terminology: The apex of the heart is formed by the left ventricle. Because the apex of the heart is close to the chest wall, the apex pulsation can often be seen or felt in the fifth intercostal space on the left side of the anterior chest wall.

2. Base of the heart: Towards the upper right rear side, it is connected to the large blood vessels entering and leaving the heart and is the relatively fixed part of the heart.

Terminology: Most of the heart base is made up of the left atrium, and a small part is made up of the right atrium. The four pulmonary veins are connected to the left atrium, and the superior and inferior vena cava open at the upper and lower parts of the right atrium respectively. Between the superior and inferior vena cava and the right pulmonary vein is the interatrial groove, which marks the posterior boundary between the left and right atria.

3. Three sides: If divided into two sides, the sternocostal surface (front) of the heart faces forward and upward, and most of it is composed of the right ventricle. The diaphragmatic surface (lower side) faces posteriorly and inferiorly, and is mostly composed of the left ventricle, which is close to the diaphragm.
