What is the amount of air that moves into the respiratory system during a single respiratory cycle?
The amount of air that is inhaled or exhaled in one breath during unforced breathing is the tidal volume.
Why does air enter the lungs upon inhalation?
During inspiration, the alveolar pressure is less than the atmospheric pressure. This causes air to flow into the alveoli. The external intercostal muscles and diaphragm contract during this phase.
What is another name for respiratory system?
Otorhinolaryngology.
Oto = ear
Rhino = nose
And then the last part, "laryngology", refers to the throat and "study of" everything mentioned before. Larynx = throat. The suffix "logy" is the "study of."
Specialty in this is sometimes called ENT (ear, nose, and throat).

What physical factors influence respiratory rate?
aerobic respiration - amount of excersize that is being performed will increase the rate of respiration as more energy is needed therefore increasing respiration to produce energy from glucose... however when not enough oxygen is being transported to the muscles, the muscles begin the process of anaerobic respiration, which is pretty much the same process that occurs in the mitochondria, however, no oxygen is used in the process, therefore creating the bi - product being lactic acid and in some yeasts and bacteria, ethanol (not humans).. an example of when the muscles go into anaerrobic respiration is in a long jog.. and aerobic respiration is used mainly for short activities ie. 20m sprint.
Do you exhale because the air pressure in the chest cavity has decreased?
No. When you exhale, you increase the pressure in your chest cavity to push out some of the air in your lungs.
How respiration is affected at high altitudes during space travel and under water?
High altitude affects respiration because there is less oxygen in the air. Because of this, more and stronger breathing is needed to supply oxygen to the bloodstream.
Why you lose the sense of smell after smell too many types of smell?
Because your nose gets confused. You can restart a new scent by sniffing the back of your hand and then smelling something different. When perfume testing, once you smell one, sniff the back of your hand, because your nose is used to the smell of your skin, and acts as a restart, and then smell the next product.
When oxygen enters the respiratory system what is the next structure upon leaving the trachea?
bronchi
What are the normal changes that occur in the respiratory system during exercise?
respiratory system change with more exercise because it is related to our cardiovascular and respiratory system.when we do exercise our heart rate increases cardiac output increases and oxygen is more utilizing and more energy is required.These all cause effect on respiratory system
How do the nostrils contribute to the process of breathing?
the nose does not help us breath. it's function is to warm, humidify, and filter the air to the lungs. thus said, it is better to breath through the nose for its benefits, rather than mouth breath which provides no protective filtration of the air.
What are signs and symptoms of respiratory failure?
Acute respiratory infections are basically the common cold. Symptoms should be runny or stuffy nose, scratchy throat, cough, sore throat, sneezing, fever, muscle aches, headache, chills, sweats. OTC meds should help ease the symptoms.
Which process drives the gas exchange from the alveoli to the capillaries?
Diffusion is the process that allows the exchange of oxygen and carbon dioxide in the alveoli. This process is one of passive transport.
How is the cat's respiratory system different from the human's?
The respiratory systems of all mammals are very much the same. There is not much difference between them at all.
What gases does the respiratory system transfer?
The cardiovascular system is where the respiratory system transfers oxygen.
What organ is part of respiratory and excretory system?
lungs considered as excretory organ because it excretes waste such as carbon dioxide and other wastes , and it is considered as respiratory because lungs involves respiration which means as the transport of gaseous materials like oxygen in and outside of the body.
A passage lined with cilia (hair like structures that are located throughout your respiratory system and ears) connects the mouth from the nose.
The Palate.
Which respiratory structure is comprised of cartilage and ligaments?
That tube is called the trachea. It is also known as the windpipe.
What is the component of respiratory system?
Some of the components of the respiratory system are the major structures like the throat, windpipe, and lungs. The other parts are smaller things like the alveoli, which are tiny sacs in the lungs where over a million of them work to transfer oxygen and carbon dioxide in and out of blood.
What is the health habits to keep the respiratory system?
Oxygen and exercise do wonders for the respiratory system.
What causes swelling of the ventricular system?
Swellings or structures within the ventricular system may be due to congenital defect, trauma, or tumor
