Bifurcation

In anatomy, a bifurcation is the point at which a division into two branches occurs, such as blood vessels or the trachea.

When an artery or vein reaches a bifurcation, it splits into two smaller vessels. This allows the blood to spread through smaller vessels and deliver oxygen and nutrients to different parts of the body.

One of the most famous examples of bifurcation is the division of the common carotid artery into the internal and external carotid arteries in the neck.

Another important example is the bifurcation of the trachea, when it divides into the right and left main bronchi, leading to the right and left lungs, respectively. This is a critical separation that allows air to pass into both lungs.

Thus, the bifurcation plays an important role in anatomy, allowing the extensive network of blood vessels and airways to efficiently supply all parts of the body with blood and air.

Bifurcation is the point where separation occurs. Separation can occur anywhere: on blood vessels, on the trachea, on the road, on the river. In nature, such separation can be of great importance, for example, the separation of blood vessels can lead to cardiac arrest, and the division of a river can lead to flooding.
In anatomy, bifurcation is a division into two branches of blood vessels. This is the point at which the blood vessel splits into two. For example, there are bifurcations in the arteries that go to the head. At this point the arteries divide into two: one goes up to the head, the other goes down to the body. The same thing happens in the veins, which also branch into two, one goes to the heart, the other to other parts of the body.
Bifurcations can be either congenital or acquired. For example, if a person has a disease that causes blood vessels to narrow, this can lead to the formation of bifurcations. Also, bifurcations can occur due to trauma or surgery.

Bifurcations are branching points formed during the embryogenesis of an organism. At each bifurcation, the process of choosing one of two possible directions for further development of the system occurs. The number of bifurcations in the body is directly proportional to the number of possible paths for the formation of key organs and tissues and, consequently, the number of branches within the body. From a biological point of view, bifurcation and its consequences are an evolutionary standard. All features of a living organism are determined by the trajectories of its evolutionary development. The historical experience of mankind allows us to consider the structures that arise in it as a result of bifurcation as a mechanism for the accumulation and concentration of general environmental requirements at a given point in time.

The anterolateral region of the lower third of the face (nasolabial region and lateral part of the nose) in a newborn often undergoes three types of nasal bifurcation: left anterolateral (the most common), right anterolateral or bilateral anterior
