What is the pulmonary artery?
The pulmonary artery (PA) is a vital and specialized artery associated with the right ventricle of the heart. The name is actually a bit deceitable because there are two pulmonary arteries. They are based on the lung strain (sometimes called the main artery) and are called the right and left pulmonary arteries. Their function is to transfer blood from the right ventricle to the lungs.
When the blood returns to the right chamber of the heart, it is blue blood, lacks oxygen and must go back to the lungs to become oches. Through contractions or pumping the right ventricle, the heart brings blood to the main pulmonary artery or trunk, and then this blood passes through the left or right pulmonary artery to reach the lungs. After oxygenation, the blood returns to the left ventricle of the heart and is pumped into the body.
In life, it is only once when most people do not need a pulmonary artery or suitcase. Like fruits, people do not take breathing to create oxygen in the lungs. Instead, they rely on the supply of the mother's oxygen through the umbilical cord. Once they were born, children and then adults needPA to maintain a normal function. However, there are some diseases that may affect the pulmonary artery.
In adults, the most common disease affecting these arteries of pulmonary hypertension. This leads to increased arteries, usually from some type of obstruction, mild or serious, in the waist. Over time, pulmonary hypertension weakens the right ventricle because it must draw heavier feeding blood into the lungs.
Some of the most devastating diseases affecting pulmonary artery are congenital or present at birth. They may include lung stenosis, which means narrowing of PA or complete absence or no function of PA, called atresia. Through surgery, it is possible to repair the stenosis of the etimes achievement of the artery. Other times, surgery is no longer a surgery on open hearts and doctors can use things such as the catheterization of the balloon to expand the arteries and prevent pulmonary hYpertenzi.
If PA is extremely damaged or almost absent, larger remedial surgical measures may be required. Some of them, like fontan surgery, include completely redirecting heart circulatory patterns so that the blood passively flows into the lungs and is not pumped into the lungs. In some cases, when one of the chambers of the heart is very weak, PA can be removed when fontan is done because it is no longer necessary.
