Structures and functions of Respiratory system

Structure of respiratory system

Respiratory system is the part in the body of human being which is responsible for breathing.
Breathing involves two important processes which are inhaling and exhaling. Inhaling is the
process of breathing air in while exhaling is the process of breathing air out.

The parts of a respiratory system
There are two parts of a respiratory system; upper respiratory tract and the lower respiratory
tract. The upper respiratory tract is made up of mouth, noise and the upper part of the trachea. On
the other hand, the lower tract comprise of trachea, bronchi, bronchiole and the lungs.


Structures and functions of Respiratory system

The mouth is the secondary opening which leads to the lungs. It serves to supplement the
function of the nasal cavity. Additionally, it also acts as a substitute in case of nasal blockage

The nose
The nose has two parts; we have the visible part which is the outer one and the inner part which
contains the nasal cavity. The nasal cavity is being divided by the nasal septum. When the air
enters the noise, it passes through two openings. It enters the external nares then passes into the
vestibule before proceeding to the next opening which is the meatuses. The meatuses have walls
which are called concha. These walls are formed by facial bones.
The air from the meatuses is channeled into two internal nares. The noise has hairs which filters
any impurities in the air as well as mucus which moisten it. The blood capillaries and cilia which
line the nasal cavity serve to filter and eliminate debris from the passing air.

This is the part of the larynx that serves to prevent food from entering the trachea. This mostly
occurs in a case that involves swallowing food by covering the opening to the airway.

The trachea is also called windpipe is the tube that connects the throat to the bronchi. Trachea
begins from the larynx, goes down through the neck leading down to the lungs before splitting
into two bronchi and into the lungs. The structure of trachea is about 12cm long by 2cm in
During inhalation, air enters the nostrils while the hairs which are present serve to filter any dust
and impurities which may be present in the hair. When the hair has been filtered, it enters the
nasal cavity which has two mucous membranes that secrete ...
