Nov 07, · on Speech and the Respiratory System. Speech, a form of human communication, is produced by three groups of organs working together: respiratory, phonatory and articulatory. The dominant elements of the respiratory system  are the lungs, the chest wall and the diaphragm. Working together, they provide the mechanical energy in form of air pressure, the aerodynamic . Primary role during speech breathing is to control vocal intensity. Loudness is directly proportional to the amount of air pressure the lungs apply to vocal folds. Resources.
Speech, a form of human communication, is produced by three groups of organs working together: respiratory, phonatory and articulatory. The dominant elements of the respiratory system  are the lungs, the chest wall and the diaphragm. The tongue, the lips, the jaw and the velum, the articulatory elements of conrtibute speech organs, modify the properties of respiratlry sounds. The extent of modification depends on several factors, including the position of articulatory organs, the intensity of sound pressurephysical properties of the tissues, etc.
The larynx is the place of phonation. The respiratory system  is located in the chest thorax — a cavity, created by rib cage and the muscles. The ribs are posteriorly connected to the vertebral column, and anteriorly to the sternum breast-bone.
This thoracic cavity is on its top limited by the shoulder blades scapuaeand on the bottom by the diaphragm. The lungs are jow within the thoracic cavity: they are a cone-shaped organ, made what are the healthiest granola bars sponge-like matter, consisting of many bronchioles that branch into numerous alveoli. The lungs and the inward surface of the cage are connected with pleural linkage, a fluid-like matter that makes possible for the lungs to expand or shrink simultaneously with the cavity.
The lungs act as bellows Crystal 20 : after the chest muscles flex, the pressure inside the lungs increases, which forces air to exit; in reverse, by lowering the diaphragm or flexing the rib muscles, the pressure inside the lungs dles, which forces the air to enter the respiratory system.
There are two important phases in the respiratory system that are related to speech: inspiration and exhalation. Inspiration, or the process of inhaling, occurs when the thoracic volume increases, which causes the lowering of the pressure in lungs. This pressure difference causes air to enter the system. The increase of space within the thorax is achieved by the rib cage moving upwards caused by shortening of intercostal muscles or by lowering of the diaphragm.
However, in situations where more energy is needed shouting, prolonged speakingthe muscles activate to help the air stream mechanism and increase the flow of air. In an experiment  described by Clark 27Ladefoged, among others, showed that significant energy must be used to maintain the air energy once the exhalation phase reaches zero capacity.

The created sound then contributd through the articulatory system, attaining its final form — one of the sounds used in the language of the speaker.

Thank you. Why are lungs important to communication. Thanks much. Thaxxx for my study ……and also easy to learn…. Leave a Reply Respiartory reply.
Major parts and organs of the human respiratory system
Apr 17, · The larynx connects the pharynx and trachea and helps to conduct air through the respiratory tract. The larynx is also called the voice box because it contains the vocal cords, which vibrate when air flows over them, thereby producing sound. You can see the vocal cords in . Main functions of the respiratory system. Inhaling and exhaling. Exchange of oxygen and carbon dioxide between the lungs and bloodstream. Exchange of oxygen and carbon dioxide between the bloodstream and tissues. Creating vibration of the vocal cords to . The respiratory system has many functions. Besides helping you inhale (breathe in) and exhale (breathe out), it: Allows you to talk and to smell. Brings air to body temperature and moisturizes it to the humidity level your body needs.
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.
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. 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.
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.
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. Your email address will not be published. This site uses Akismet to reduce spam.
