What Is the Hilum of the Lung

the hilum of the lung is a triangular

impression that allows the structures

which make up the root of the lung to

enter and exit a hilum is a section of

an organ where other types of structures

like veins or arteries can enter the

hilum of the lung is a wedge-shaped

section in the central area of the lung

that permits arteries veins nerves

bronchi and other structures to enter

and exit both human lungs have a hilar

region meaning both lungs have an area

called the hilum this region aids the

lungs route in anchoring the lungs to

the heart trachea and other structures

lungs are organs of respiration and are

part of the respiratory system they pull

oxygen from the environment and

transport it into the bloodstream the

lungs are soft elastic organs that are

lightweight when their tissues are

healthy humans have two lungs one on

either side of the chest cavity which

are separated from each other by the

heart and trachea the area where the

heart trachea and other structures are

located is called the middle mediastinal

air reaches the lungs via the trachea

which is commonly called the windpipe in

humans and some other animals the

trachea is a few but that connect the

lungs to the upper part of the

respiratory system which consists of the

mouth nasal cavity pharynx and larynx

when the trachea reaches a point in the

mediastinum called the Carina it splits

into two tubes called the primary

bronchi the right and left primary

bronchi enter the corresponding lung and

subdivide into more bronchial branches

each lung can be divided into four main

sections the apex Beggs root and the

Hylas or hilum of the lung the apex is

the uppermost part of the human lung and

it is rounded in shape it extends as

high as the bottom or root of the human

neck and as low as the first rib the

base of the lung is wide and concave and

sits on the surface of the diaphragm

above the middle mediastinal area is the

root of the lung which connects the

to both the trachea and the heart the

root of the lung is composed of several

structures including the pulmonary

artery and pulmonary veins all of which

are encased in a layer of pleura which

is a thin smooth layer of protective

tissue the hilum of the lung is the

roots point of attachment to the lung

the area surrounding the hilum of the

lung is called the perilla region
