What is the primary function of a respiration system?
The primary function of the respiratory system is to supply the blood with oxygen in order for the blood to deliver oxygen to all parts of the body. The respiratory system does this through breathing. When we breathe, we inhale oxygen and exhale carbon dioxide.
What is the main function of respiratory system?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

How to check if your respiratory system is working?
To see if your respiratory system is working as it should, your healthcare provider may use imaging tests such as a CT scan or MRI. These tests allow your provider to see swelling or blockages in your lungs and other parts of your respiratory system.
How does oxygen get into the lungs?
Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called external respiration. This respiratory process takes place through hundreds of millions of microscopic sacs called alveoli. Oxygen from inhaled air diffuses from the alveoli into pulmonary capillaries surrounding them.
What are the functions of the respiratory system?
The following are the five key functions of the respiratory system. 1. Inhalation and Exhalation Are Pulmonary Ventilation—That’ s Breathing. The respiratory system aids in breathing, also called pulmonary ventilation. In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth).
How does pulmonary ventilation work?
In pulmonary ventilation, air is inhaled through the nasal and oral cavities (the nose and mouth). It moves through the pharynx, larynx, and trachea into the lungs. Then air is exhaled, flowing back through the same pathway. Changes to the volume and air pressure in the lungs trigger pulmonary ventilation.
What happens when you exhale?
During exhalation, air passes from the lungs through the larynx, or “voice box.”. When we speak, muscles in the larynx move the arytenoid cartilages. The arytenoid cartilages push the vocal cords, or vocal folds, together. When the cords are pushed together, air passing between them makes them vibrate, creating sound.
How does olfaction work?
The process of olfaction begins with olfactory fibers that line the nasal cavities inside the nose. As air enters the cavities, some chemicals in the air bind to and activate nervous system receptors on the cilia. This stimulus sends a signal to the brain: neurons take the signal from the nasal cavities through openings in the ethmoid bone, and then to the olfactory bulbs. The signal then travels from the olfactory bulbs, along cranial nerve 1, to the olfactory area of the cerebral cortex.
Where does carbon dioxide diffuse?
It diffuses through the capillary walls into body tissues. Meanwhile, carbon dioxide diffuses from the tissues into red blood cells and plasma. The deoxygenated blood carries the carbon dioxide back to the lungs for release. All 3D models in the page have loaded.
Which cell brings oxygen to the lungs?
Red blood cell. Red blood cells carry inhaled oxygen to the body's tissues and bring carbon dioxide back to the lungs to be exhaled. 4. Air Vibrating the Vocal Cords Creates Sound. Phonation is the creation of sound by structures in the upper respiratory tract of the respiratory system.
What is the respiratory system?
By: HowStuffWorks.com Contributors. The respiratory system is the group of tissues and organs in your body that enable you to breathe. This system includes your airways, your lungs and the blood vessels and muscles attached to them that work together so you can breathe. The respiratory system's primary function is to supply oxygen to all ...
What is the hair in your airways?
Cilia (tiny mucous-covered hairs) in your airways entrap foreign particles and germs to filter the air that you breathe. You then cough or sneeze the particles out of your body. The diaphragm, abdominal muscles and other muscles help your lungs expand and contract so you can inhale and exhale. When you inhale, the air goes through ...
Where does carbon dioxide go when you inhale?
When you inhale, the air goes through the bronchii in your lungs to blood vessels that connect to veins and arteries. These veins and arteries carry the blood throughout your body. When you exhale, the carbon dioxide goes out the same way, exiting your body through your nose and mouth.
What happens if you can't breathe?
If you can't breathe or can't breathe well, not only will your body not receive enough oxygen to keep it running, but it will also be poisoned by the carbon dioxide that is building up in your blood and has nowhere to go. Advertisement. . Cite This!
What is the respiratory system?
The respiratory system is made up of more than just the lungs; it also includes your nose, throat, larynx, windpipe, bronchi, alveolar ducts, and respiratory membrane. The function of the respiratory system is to deliver air to the lungs. Oxygen in the air diffuses out of the lungs and into the blood, while carbon dioxide diffuses in ...
Which system transports oxygen?
Gas transport, carried out by the cardiovascular system, is the process of distributing the oxygen throughout the body and collecting CO 2and returning it to the lungs. Internal respiration is the process of gas exchange between the blood, the interstitial fluids (fluids surrounding the cells), and the cells.
What part of the body controls air temperature?
The sinuses help to regulate air temperature as you breathe. In addition to entering through the nasal cavity, air can also enter through the mouth. Once air enters the body, it flows into the lower portion of the upper respiratory system with the pharynx and larynx. The pharynx, or throat, allows for the passage of air from ...
How does deoxygenated blood get oxygenated?
Once the deoxygenated blood reaches the alveoli, it releases the carbon dioxide in exchange for oxygen. The blood is now oxygenated. The oxygenated blood then travels from the lungs back to the heart, where it’s released back into the circulatory system.
What is the name of the disease that causes the alveoli to become inflamed with pus and fluid?
Pneumonia. Pneumonia is an infection that causes the alveoli to become inflamed with pus and fluid. SARS, or severe acute respiratory syndrome, and COVID-19 both cause pneumonia -like symptoms, which are both caused by the coronavirus. This family of viruses has been linked to other severe respiratory infections. If left untreated, pneumonia can be fatal. Symptoms include shortness of breath, chest pain, coughing with mucus, and more.

What is the respiratory system?
All About the Human Respiratory System. The respiratory system is responsible for the exchange of carbon dioxide and oxygen in the human body. This system also helps remove metabolic waste products and keep pH levels in check. The major parts of the respiratory system include the upper respiratory tract and the lower respiratory tract.
Where is the upper respiratory tract located?
The upper respiratory tract begins with the sinuses and nasal cavity, both of which are in the area behind the nose.
Which part of the respiratory system allows air to flow directly to the lungs?
Lower respiratory tract. The trachea, or windpipe, is the passage that allows air to flow directly to the lungs. This tube is very rigid and is composed of multiple tracheal rings. Anything that causes the trachea to narrow, such as inflammation or obstruction, will restrict oxygen flow to the lungs.
