inspiration.....external nares, nasal cavity, internal nares, epiglotis, pharynx,larynx,trachea, bronchi,bronchioles,alveoli,capllaries....(alveoli carries the oxygen where as the capallaries bring the deoxygenated oxygen from the veins and gas exchange occurs)

sounds--auricle,tympanic membrane, maleus,incus, stapes, oval window of ossicle, basilar membrane bends and sends it to ( )nerve forgot the name

can some1 fill in that blank...and tell me if rest of it is right also if u can think of other pathways that may be importnant to know.

Ear: Pinna -> Aud Canal -> Tymp Membrane -> Malleus -> Incus -> Stapes -> Semicircular canal -> cochlea -> Eustacian tube

2 of the more important pathways are the digestive and the circulation (beginning with the heart and then coming back to it)

2 of the more important pathways are the digestive and the circulation (beginning with the heart and then coming back to it)

digestive: oral cavity, pharynx, esophogus (cardiac and pyloric sphincter), stomach, small intestine, large intestine, poo poo

circulatory system: Right atrium, right ventricle via tricuspid valve, pulmonary arteries (deoxy blood), lungs, pulmonary veins (oxy blood), left atrium, left ventricle (via mitral valve), aorta (semilunar valves are here), arteries, arterioles, capillaries, venioles, veins, superior vena cava/inferior vena cava lead back to the right atrium....

Superior = upper body
Inferior = lower body

Someone correct me if iam wrong...thanks

all good except pyloric sphincter is between the stomach and duodenum and semilunar valves are also on the pulmonary artery.

don't forgot to know the different sections of the small and large intestines either.

correct me if im wrong but isnt semicircular canal part of the gravity and movement...are the also part of amplifying sound

does ossicles fall under semicircular

also that nerve i was thingking of is cochlear nerve

so with all that where do they fall in.....so auditary canal tymp.mem., Malleus,incus,stapes..ovalwindow of cochlea..eustasian tube? cochlear nerve?
