Which is the largest artery in our body?
Arteries are blood vessels. Arteries carry oxygenated blood from the heart to the tissues of the body. Each artery is a muscular tube. The aorta is the largest blood vessel in our body. It also provides nutrients and hormones. The branches of the aorta ensure that oxygenated blood reaches the internal organs and surrounding supporting tissue.
The largest artery in the human body is the aorta, which exits the left ventricle of the heart. The aorta turns into a network of small arteries that circulate throughout the body. The smaller branches of arteries are called arterioles and capillaries.
Arteries withstand high force blood pressure because blood is pushed through the heart with great pressure so that it can be carried throughout the body. The walls of the arteries are thicker, more elastic and more muscular than other veins in the body to withstand this pressure.
The walls of small arteries are more muscular in structure. The smooth muscles in the walls of these small arteries contract or dilate to control blood flow.
In this way, the body controls how much blood flows to different parts of the body under different conditions. The regulation of blood flow also affects blood pressure.

Arteries suffer lower blood pressure than arteries because of their larger number of arteries, less blood volume, and their distance from the direct pressure of the heart. Arterial walls are much thinner than arteries. They play an important role in micro-circulation.
