Where is the heart located? Where is the human heart located

The heart is located between the second and fifth ribs of the rib cage. The heart of the average person is located on the left side of the body, and the body surface position is about between the second rib and the fifth rib on the left side of the sternum, and the hand is at the intersection of the left midclavicular line (the vertical line passing through the midpoint of the clavicle) and the fifth rib, and the apical pulse can be palpable.

The human heart is located in the lower left of the middle of the chest. The human heart is located in the middle of the chest and is about the size of a fist and weighs about 250 grams. Women's hearts are usually smaller and lighter than men's.

The human heart is shaped like a peach, located above the diaphragm, and the lungs are on the left.

The heart is composed of myocardium, the left atrium, the left ventricle, the right atrium, and the right ventricle, of which the left ventricular wall is the thickest, and these four chambers are the only way for the systemic circulation and pulmonary circulation.

The function of the heart is to promote blood flow, provide sufficient blood flow to organs and tissues, take away the end products of metabolism, and maintain normal metabolism and function of cells.

In general, the heart is located on the left side of the body, about the second to fifth ribs on the left side of the sternum.

The apical pulse can be palpated by placing the hand at the intersection of the left midclavicular line (the vertical line passing through the midpoint of the clavicle) and the fifth intercostal space.

A very small number of hearts are located on the left side of the body, and other organs also grow on the opposite side symmetrically with ordinary people.

The heart is located in the thoracic cavity, above the diaphragm, between the two lungs, about 2 3 on the left side of the midline and 1 3 on the right side of the midline.

The heart resembles an inverted cone that is slightly flattened anteriorly and backwards, and also resembles a "peach".

The apex is anteriorly inferior to the left, the apical pulse point is 1 cm medial to the midclavicular line of the fifth intercostal space, and the base of the heart is wide with large blood vessels accessing and exiting.

The size of a heart is the size of its own fist. There are four main chambers, the left atrium, the right atrium, the left ventricle, the right ventricle, the left and right atria and the left and right ventricles do not communicate with each other. There is a mitral valve between the left atrium and the left ventricle, and a tricuspid valve between the right atrium and the right ventricle.

I remember learning when I was in school that the heart is above the left half of the body, not in the middle, and the size of a fist.

The human heart is behind the sternum and is slightly to the left. In the fifth intercostal space of the thoracic vertebrae, the apical beating of the heart can be clearly heard. The heart is divided into four chambers: left ventricle, right ventricle, left atrium, and right atrium.

Separation through the atrioventricular valves, including mitral and tricuspid valves. The heart is constantly beating in hard work every day to ensure the normal blood of the human body**, which is an important organ of the human body, and if the heart stops beating, life will also end. Therefore, we must pay attention to protecting the heart and reduce smoking and alcohol to prevent diseases such as myocardial ischemia and cardiac atherosclerosis.

At the same time, avoid indiscriminate medication to prevent accelerating the aging of blood vessels and heart.

Professor Ding Rongjing will explain in detail where the heart is located in the human body.

Written incorrectly, a few are located on the right.

The heart is an important organ of the human body, located on the left side of the chest, and you can feel a regular beat when you gently stroke it with your hand.

1. Under normal circumstances, the human heart is located in the lower left of the middle of the chest cavity, and its volume is the same as that of its own fist.

2. The heart is one of the important organs of the human body, mainly composed of myocardium, which is divided into four chambers: left ventricle, left atrium, right ventricle and right atrium. The left ventricle is thicker than the other three chambers because it is connected to the aorta and needs to be forcefully contracted to pump blood. The heart is responsible for pumping blood and providing oxygen to tissues and organs throughout the body, so keeping it healthy is crucial.

3. Abnormal heart function may cause various diseases, such as coronary heart disease, angina, arrhythmia, etc., which are mainly manifested as symptoms of dyspnea, palpitation, and chest pain. Usually pay attention to rest, avoid staying up late, and eat more vitamin-rich fruits and vegetables in the diet, which have certain benefits for cardiovascular health.

Diagram of human internal organs:

1. Heart: 1. Heart wall. Including: endocardium, myocardium, epicardium.

2. Heart and bones, including: 2 fibrous triangles (i.e., left and right fiber triangles), 4 valve annulus (i.e., pulmonary annulus, aortic annulus, mitral annulus, tricuspid annulus).

3. Intercardiac septum, including: atrial septum and ventricular septum.

4. The lumen of the heart, the right atrium includes: the propria propria and vena cava sinus, and the right ventricle includes: right ventricular inflow tract and right ventricular outflow tract.

The left atrium includes: left atrial appendage, left atrial sinus, and left ventricle includes: left ventricular inflow tract, left ventricular outflow tract.

5. The conduction system of the heart, the sinus node and the atrioventricular node include: anterior internodal bundle, middle internodal bundle, posterior internodal bundle, and the atrioventricular bundle includes: left bundle branch, right bundle branch, and Purkinje fiber network.
