respiratory

• all air is warmed, moistened, and filtered
• air is warmed by body temp, moistened by mucus and saliva, and is filtered by the adenoids and tonsils
• the flow of air is this (from nose): nose, nasal cavity, nasopharynx, oropharaynx, laryngopharynx, epiglottis, larynx, trachea, broni, bronchioles, alveoli
• the larynx is the voice box, it holds the vocal cords and produces sound
• the respiratory's system main function is oxygen in, carbon dioxide out
• the primary organ of the respiratory system is the lungs
• pulmo means lung
• the pharynx is also known as the throat
• the pharynx connects the cavities to the epiglottis
• which two systems are related to the pharynx?

  digestive and respiratory
• the pharynx is made of three parts: nasopharynx, oropharynx, laryngopharynx
• the epiglottis is a flap of elastic cartilage attached to the larynx that closes when food passes by
• what property does the epiglottis use to close when food passes through?

  elasticity property
• the trachea is a hollow tube that connects the larynx to the bronchi that is covered in cartilage rings to hold it open
• the trachea is also called the windpipe
• the bronchi are hollow tubes that connect the trachea to the bronchioles
• the bronchi are the two major air passageways of the lungs
• bronchioles are the smallest air passageways in the lungs
• the bronchioles connect bronchi to alveoli
• the alveoli are air sacs at the end of the bronchioles where diffusion takes place
• the alveoli is where the main function of the lungs takes place
• the alveoli are shaped liked balls to increase surface area
• surface area in alveoli is used to exchange gases efficiently and fast
• what type of air goes through the right bronchi because it is straighter?

  infected air
• what is the only organ in the respiratory system that never touches air?

  diaphragm
• the diaphragm is a sheet of internal skeletal muscle that is in bottom of the thoracic cavity and is dome shaped
• when the diaphragm contracts, it inhales, and when it recoils, it exhales
• the diaphragm's other function is to physically separate the thoracic cavity from the abdominal cavity
• its harder to breathe during exercise because cells are making waste quicker (CO2) which needs to be exhaled
• acute means short-term or sudden onset
• chronic means long term or constant
• the two COPD diseases are emphysema and chronic bronchitis
• what is the other name of influenza?

  flu
• influenza is a virus that settles in the nose or throat
• is influenza acute or chronic?

  acute
• is pneumonia acute or chronic?

  Acute
• is bronchitis acute or chronic?

  acute
• pneumonia is a lung infection that can viral or bacterial that can come from the cold or flu
• pneumonia is where your alveoli sacs fill with fluid and pus
• bronchITIS is the inflammation of the bronchi
