Aortic bulb

**The aortic bulb** is an anatomical structure located on the posterior surface of the aortic arch and is the part that provides communication between the aortic arch and the ascending thick aorta. It is also called the bulb of the aortic arch and is an expanded area at the posterior end of the aortic arch where the arteries begin their ascent to the upper part of the body.

The aortic bulbs play an important role in the functioning of the cardiovascular system, ensuring the stability of branching and blood supply to the upper parts of the body. They are also involved in regulating blood pressure and metabolism, and may contribute to the development of other structures such as blood vessels in the chest and limbs.

One of the key functions of the aortic bulb is the ability to change the diameter of the artery depending on need. When blood pressure rises, the inner lining of the aortic bulb can contract, causing the artery to narrow and reducing pressure throughout the circulatory system. This allows the heart to receive enough blood to cope with the increasing demand of energy and impulses from organs and tissues.

In healthy people, the aortic bulbs are located behind the abdominal wall and can be felt on the back of the neck. However, in patients

The aortic bulb is one of the most important blood vessels in the human body. It is located in the chest cavity and performs the function of transporting blood from the heart to other organs. In this article we will look at the anatomical structure of the aortic bulb, its functions and possible diseases.

Anatomical structure of the aortic bulb The aortic bulb is one of the largest blood vessels in the human body. Its length is about 15 cm, and its diameter is from one to two centimeters. The bulb consists of three main elements: the ascending aorta, the aortic arch and the descending aorta.

The ascending aorta begins from the left ventricle of the heart and passes through the diaphragm and the abdominal cavity.
