The respiratory system is one of the most important systems of our body as it is responsible for inflow of oxygen. Its primary function is to supply blood with oxygen so that the blood can deliver oxygen to all other parts of the body. Oxygen paves way into our respiratory system through our nose and mouth. To be pointblank, it facilitates breathing in our body by regulating the inflow of oxygen and the outflow of carbon dioxide. We all know that carbon dioxide is a waste product in our body, and our respiratory system allows us to lead a healthy life by eradicating this waste product.
Our respiratory system consists of nostrils, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and lungs. That being said, let’s have a look at the parts of the respiratory system that triggers speech along with a little description about each of these parts.
The nostrils are one of the channels of our nose that keeps the air warm while we inhale air. It also helps us get rid of the moisture, while we exhale. Each of our nostrils is used for a specific time period. The nostrils switch function in every four hours. We experience nasal cycle when our nostrils swell. It regains its original shape in due course of time.
It’s the large space that you witness behind and above your nose. The nasal cavity conditions the air passed from our respiratory tract and our nose. The air is humidified and the dust particles are thrown away by our nasal cavity.
Pharynx forms a part of our neck and throat. It’s based behind the nasal cavity and our mouth. It’s an important part of our respiratory and digestive system. The air that we inhale passes through the pharynx. The food that we intake on daily basis also passes through the pharynx. It contains a connective tissue within it which is commonly referred as epiglottis. This tissue prevents choking when we consume food. As such, the pharynx is classified into three different sections mainly called as nasopharynx, oropharynx, and laryngopharynx.
The pharynx also plays an important role for vocalization amongst human beings. When a person experiences oral allergy syndrome, hay fever or similar ailments, it serves as the reacting part to factors that are responsible for producing common symptoms like itching and burning sensation.
Often referred as voice box, it’s an organ which is mainly found in the neck of mammals. It’s used for sound protection and for sound generation. We are able to speak because of the presence of vocal cords that are found in the voice box and at the top of the trachea. While we speak, a center in our brain sends out a signal to the tiny muscles responsible for altering the length and position of the cords, thereby producing different sounds. The resulting sounds are modified with the aid of our tongue, cheeks and lips.
