what is hypertension?
high blood pressure 140/90; genetics/lifestyle cause high blood pressure. maintains a healthy body weight.
inspiration is what?
breathing in (inhalation)
what is expiration?
moving away from lungs (exhale)
what is the Pharynx and what happens there?
its the throat; it connects the nasal & oral cavity to the larynx.
what is the larynx and what happens there?
it is a box like structure (made of cartilage) “Voice box” holds vocal chords.
what is the glottis?
It’s the region within your voice box that contains your vocal cords “opening”
what is the epiglottis?
prevents void in voice box, opens & closes. The epiglottis is a small, movable “lid” just above the larynx that prevents food and drink from entering the windpipe

“wind pipe”, cilia is found here so its ciliated, filter sweep. mucus secretes mucous here
what is bronchi?
The large air passages that lead from the trachea (windpipe) to the lungs.
what are the bronchioles?
Bronchioles are the smallest air passageways in the lungs, branching from the bronchi and delivering air to the alveoli

what is emphysema?
alveoli surface area is reduced, it limits gas exchange, lungs lose elasticity, heart & brain are effected, lack of oxygen, caused from smoking
what is asthma?
breathing, coughing, mucous, animal scent can make it worse, spasm reduce diameter of airways.
