Document Summary

Basic function is to supply the body with oxygen and to dispose of carbon dioxide. Includes: nose, nasal cavity, and paranasal sinuses, pharynx, larynx, and trachea, bronchi and smaller branches, lugs and alveoli. Respiratory organs are divided into two: conducting zone these carry the air to the sites of gas exchange leads to the respiratory zone, respiratory zine site where gas exchange occurs. This is the part of the respiratory system that is visible externally. Works to condition and filter air, mainly to warm up the air and filter out any harsh chemicals that might be entering our system. Divided into: external nose frontal and nasal bones are superiorly, maxillary bones laterally, and hyaline cartilage is an anterior aspect of nose. External nares, which are nostrils leads into the pharynx - nostrils are divided by the nasal septum. Continuous with nasopharynx posterior nasal apertures called choanae (kind of like a hole or an opening)

a) -------------------- serves as a sound resonating chamber; contains tonsils; directs air inferiorly

b) ------------------- passes air from pharynx into windpipe; site of sound production

c) ------------------ resonate(s) sound; not part of pharynx

D) ------------------ opening from oral cavity into pharynx

E) ----------------- carries air to a segment of a lung

F) -------------------- carries air directly into a respiratory bronchiole

G) ----------------- surround the lungs

H) ------------------ reduces surface tension at sites of gas exchange

i) -------------------- actual sites of gas exchange

j) --------------------- normal, quiet breathing

o) ------------------- residual volume + expiratory reserve volume; usually about 2400 mL in males

p) -------------------- states that the amount of gas that will dissolve in a liquid is proportional to the partial pressure of that gas and its solubility

q) ---------------- when pH decreases, O₂ saturation of hemoglobin decreases
