The Left Ventricle of the Heart

The left ventricle left ventricle of the heart is one of the four cavities of the heart. As the largest room it has an elliptical shape and occupies most of the left side of the heart and the front side. It also occupies most of the apex of the heart. The left ventricular wall is denser and stronger than the right ventricular wall. The thicker wall of the left ventricle supports tremendous pressure, it is to draw blood under great pressure from the heart. When the left atrium contracts, the mitral valve opens and releases the stored oxygen-rich blood into the left ventricle.

The left ventricle of the heart pumps oxygen-rich blood into the artery, but this rhythmic pressure is far from the vein and is on the other side of the millions of small capillaries in the body. In these capillaries, blood supplies nutrients and oxygen to the cells and collects waste and carbon dioxide from the cells. As nutrient-depleted blood leaves the capillary, it enters a larger, lower pressure vein. When a thrombus forms a vein it is a life-threatening medical emergency. It is necessary to remove the thrombus and improve the condition causing thrombosis. If the thrombus ruptures, it passes through the right ventricle of the heart and enters the lung where it is trapped in small capillaries, causing so-called pulmonary embolism, a greater medical emergency.

Oxygenated blood leaving millions of pulmonary capillaries enters the other side of the heart, first into the left atrium and then into the left ventricle. Oxygen-enriched blood is pumped from the left ventricle through all of the arterial circulation of the body to all muscles, tissues and organs. In this way, our kidney, brain, liver, heart, bone and other tissues can get important oxygen. (When arterial blood gas analysis for oxygen measurement is performed, a small sample is inserted into the radial artery of the wrist to obtain a blood sample behind the thumb. Unlike venous blood, arterial blood reflects the state of gas exchange For the examination of patients with multiple pulmonary diseases.) Diagram and systemic blood circulation.
