Document Summary
Respiratory system: ventilation: movement of air into & out of lungs (breathing, external respiration: gas exchange between air in lungs & blood; transport of o2 & co2 into the blood. Internal respiration: gas exchange b/n blood & tissue; taking gases & moving them into/ out of the tissues from the blood. Divided into 2 parts: upper respiratory system. Conducting zones vs respiratory zones: conducting zones: where we have movement of air but no gas exchange. Upper & lower resp structures: respiratory zones: where gas exchange is actually happening. There to make sure no particles make it into the respiratory system. Nose is made of cartilage & bone; cartilage helps to make the openings (external nares) Just inside the nares is the nasal vestibule; they are stratified squamous epithelial cell lined with hairs; enables us to trap large particles that are floating around in the air (1st line of defense)
