Vein Pulmonary Inferior Left

The inferior left pulmonary vein (lat. vena pulmonalis sinistra) is the largest and leftmost vein in the superior vena cava system. It is a continuation of the pulmonary trunk, which is shaped like the letter “S”. The inferior left pulmonary vein begins from the right ventricle of the heart and passes through the lungs, where it collects blood from all pulmonary vessels and drains it into the superior vena cava.

The pulmonary inferior left vein plays an important role in blood circulation. It delivers oxygenated blood from the lungs to the heart and further to other organs and systems of the body. In addition, the pulmonary inferior left vein is involved in the regulation of blood pressure, since it can contract and expand depending on the body's need for blood.

One of the features of the pulmonary inferior left vein is its ability to expand and contract. This is because veins have muscular walls that can contract and relax, allowing them to adapt to changes in blood pressure and blood volume.

In addition, the pulmonary inferior left vein can be susceptible to various diseases, such as thrombosis, inflammation and damage to the walls. This can lead to disruption of its function and poor circulation.

Thus, the pulmonary inferior left vein is an important element of the circulatory system and plays an important role in maintaining human health.

Pulmonary vein inferior, left

Description of the inferior left pulmonary vein The superior pulmonary vein, left (lat. vena pulmonalis superior sinistra) is a small vein emerging from the root of the lungs and collecting blood from the entire surface of the left lung, with the exception of the basal and anterior sections. Entering the chest cavity, it connects first with the lobar vein, and then with two or three superficial veins, giving part of its blood back to the left brachiocephalic vein.

The left-sided branch of the descending aorta is the bronchial artery, which supplies the bronchi and the pulmonary artery system. The T8 intercostal nerve also connects the left chest wall to this organ. The left-sided second finger on the hand corresponds to the lower end of the 6th intercostal space. The superficial nerve of this finger innervates the diaphragm when it is flexed.

The inferior vena cava is divided into two large vessels - the right and left pulmonary veins, which branch in the right side of the chest cavity. The right humerus is connected by a tendon to the biceps brachii muscle, under which is the subclavian artery. The lower chamber of the right heart is opened in the wall of the inferior vena cava at a small septal foramen, to which the paravertebral body of the second thoracic vertebra is adjacent in front.
