Our body is just like New York City. The latter is built with countless streets and railways in order for public transportation. These streets are intertwined within the metropolis in order to serve as a connection from one place to another. Just like New York, our body is also made up of thousands of passageways. However, instead of having cars, these passages cater blood in order to be transported to the different parts of our body. These channels are otherwise called as blood vessels.
Our blood vessels are classified into two types, the veins and arteries. In review of the fundamentals of human anatomy, the veins are known to carry deoxygenated blood coming from the various tissues of the body towards the heart. The arteries, on the other hand, transports oxygenated blood from the heart to be used by the cells of the body. This circulation is part of our body’s cardiovascular system.
The cardiovascular system’s primary purpose is to transport nutrients and oxygen (via blood) to our body tissues for nourishment. This is why it makes use of blood vessels in order to serve as pathways for the blood. Arteries could be seen all throughout our bodies. Some are small and very narrow, while there are also some that are thick and large. So what is the largest artery in the body?
The largest artery in our body can also be located near our heart. This blood vessel is called the aorta. The aorta is located superior or above the heart structure. It is attached to the heart’s left ventricle as it receives the most amount of blood to be pumped back to the system. As we all know, the left ventricle is also called the “workhorse” of the heart since it pumps the hardest for the aorta to receive an adequate amount of blood.
The aorta is just like any other artery in the body. Its wall tissues are also made of three different layers, the smooth inner layer tissue, the muscular middle layer (which is the one responsible in dilating and constricting the vessels) and the thin outer layer. Like any other vessels, the aorta is also very elastic, which is made possible by the connective fibers seen in the aortic wall. This elasticity is useful especially if a large amount of blood is received from the pressure of the left ventricle contraction. The aorta has also two main parts, the ascending aorta and the descending aorta. The ascending aorta carries blood towards the body structures that are seen above the heart such as the neck and head. The descending aorta, otherwise, carries blood towards the abdomen and the extremities.
The aorta may be large and powerful, but it is also prone to having problems such as aneurysm or the weakening of the arterial wall. If this condition worsens, this could lead to massive internal hemorrhage, which can also eventually cause death. That is why taking good care of each and every part of our body is always important in order to keep our little “city” inside our body peaceful and trouble free.
