Aorta (Aorta, Pl. Aortae Or Aortas)

The aorta is the largest artery in the human body, which is responsible for supplying oxygen and nutrients to organs and tissues. It starts from the left ventricle of the heart and extends throughout the body, giving off many branches that provide blood supply to all organs and tissues. In this article we will look at the structure of the aorta, its functions and diseases associated with this artery.

Aortic structure:

The aorta consists of several parts that perform different functions. It starts from the aortic bulb, which is located in the left ventricle of the heart, and continues upward, forming the ascending aorta. Next, it bends around the aortic arch and descends to form the descending aorta, which passes in front of the spine.

Along the way, many branches depart from the aorta, which provide blood supply to all organs and tissues. At the level of the IV lumbar vertebra, the aorta divides into two common iliac arteries - the right and left. The section of the descending aorta from the aortic arch to the diaphragm is called the thoracic aorta, and the section located below the diaphragm is the abdominal aorta.

Functions of the aorta:

The aorta is the main artery in the human body, which is responsible for supplying oxygen and nutrients to organs and tissues. It provides blood supply to the brain, chest, abdomen, pelvis and limbs. In addition, the aorta is an important element of blood circulation and is responsible for maintaining optimal blood pressure in the body.

Aortic diseases:

The aorta, like any artery, can be subject to various diseases. One of the most common diseases is aortic stenosis, which is characterized by narrow valves in the aorta that impede normal blood circulation.

The aorta can also be affected by an aneurysm - an enlargement of the artery wall, which can lead to its rupture. Other diseases associated with the aorta include aortic regurgitation, aortitis, and aortic thrombosis.

In conclusion, the aorta is an important element of blood circulation in the human body, from which all other arteries arise. Its structure and functions are closely related to the functioning of the heart and other organs. Therefore, any diseases of the aorta can seriously disrupt the functioning of the entire body and require timely treatment. Regular medical examinations and monitoring of the condition of the aorta can help prevent the development of serious diseases and maintain a person's health.

Aorta - This is the main artery that supplies blood to all organs and tissues of the body. It begins from the left ventricle of the heart and passes through the chest and abdominal cavities, where it branches into many smaller arteries.

The aorta has a complex structure and consists of three main sections: ascending, arcuate and descending. The ascending section begins from the left ventricle and goes around the apex of the heart, forming the aortic arch. The arcuate section runs along the spine and ends at the level of the IV lumbar vertebra. The descending section descends below the diaphragm and is divided into the right and left common iliac arteries.

Numerous branches branch off from the aorta, which supply blood to various organs and systems of the body. Among them are large vessels such as the carotid arteries, subclavian arteries and renal arteries, which supply blood to the brain, upper limbs, kidneys and abdominal organs.

However, the aorta not only supplies blood to the organs, but is also involved in the regulation of blood pressure and metabolism. For example, enlargement of the aorta can lead to increased pressure in the circulatory system and deterioration of blood supply to organs. In addition, the aortic pulse is a pressure fluctuation in the aorta that can be used to assess the condition of the cardiovascular system.

Thus, the aorta is an important element of the cardiovascular system and plays an important role in supplying the body with blood and maintaining its functions.

The aorta is the main artery in the human body, which supplies blood to all organs and tissues. It begins from the left ventricle of the heart and passes through the chest, then descends into the abdominal cavity. Along the way, many large and small arteries branch off from the aorta, which supply blood to various organs and tissues of the body.

The aorta consists of several sections: ascending, descending and thoracic. The ascending section starts from the left ventricle and goes up to the aortic arch. The descending section goes down to the diaphragm and divides into two iliac arteries: the right and left. The thoracic aorta is located in the chest and supplies blood to the lungs, heart, liver, kidneys and other organs. The abdominal section passes through the abdominal cavity and supplies blood to the intestines, stomach, pancreas and other abdominal organs.

The aorta also contains valves that help regulate blood flow and prevent backflow of blood. In addition, the aorta contains pressure regulators that control blood pressure in the body.

The importance of the aorta is that it provides oxygen and nutrients to all organs and tissues of the body. If the aorta is damaged or blocked, it can cause serious illness and even death. Therefore, it is important to monitor the health of the aorta and undergo regular medical examinations.
