Each of these parts are very important as they help bring oxygen into the body which is key to the Human Body survival. The nasal and nose cavity form the main external opening and is the first section of the airway. This is the first place where air enters the body. Next the air moves down to the larynx. The larynx is responsible for controlling airflow and providing vocalization to the Human Body. The similar sounding pharynx is responsible for conducting air to and from the trachea. Meanwhile, the trachea is responsible for connecting the larynx to the bronchi and allowing air to pass through the neck and into the lungs. The bronchi are like the trachea's assistants as they help move air from the trachea into the lungs. The lungs are responsible for filtering the carbon dioxide and oxygen from each other and allowing us to breathe. They also integrate the oxygen into red blood cells which help us breathe. They also help send out carbon dioxide when we breathe out. The last stop on our tour will be the diaphagram. The diaphagram is a muscle that separates the chest from the abdomen. The diaphragm is the main muscle of respiration as contraction of the diaphragm muscle helps expand the lungs during inspiration when someone is breathing air in.
Added Protection
While travelling through the Respiratory System you will see white streaks above you. These streaks are the ribs. The ribs are responsible for protecting the vital organs and blood vessels within the Respiratory System. Also it is specialized to to contract and expand along with the lungs to allow easier breathing while still protecting you.
Diaphagram. The Real MVP
The diaphagram is extremley important and plays a big function in the breathing process.
When we breathe, the diaphragm is drawn down until Iit literally becomes flat. At the same time, the muscles around the ribs pull them up. The chest, or thoracic, cavity becomes deeper and larger, making more air space and this is all pushed by the muscle strength of the diaphagram. For example, singers can hold notes for very long as their diaphagram has become strong from practice and air usage and training thus increasing its capacity. Overall, the diaphagram plays a big role in breathing.
Behind the Scenes:
Breathing Rate
The science behind breathing rate is very interesting.
A respiratory control center in your brain commands your breathing. This center sends out signals down your spine and to the muscles involved in breathing.
These signals make sure your breathing muscles contract and relax regularly. This allows your breathing to happen without you being aware of it.
To a certain amount, you can change your breathing rate, such as by breathing faster or holding your breath. Your emotions also can change your breathing rate. For example, being scared or angry can affect your breathing pattern as you start panting and etc.Your breathing will change depending on how active you are and the condition of the air around you. For example, you need to breathe more often when you do physical activity. Your body has many sensors in your brain, blood vessels, muscles, and lungs.
Sensors in the brain and in two major blood vessels detect carbon dioxide or oxygen levels in your blood and change your breathing rate as needed. Overall, the science behind breathing rate is very interesting.
