Document Summary

Respiratory system: nose, nasal cavity, pharynx (throat), larynx (voice box), trachea (windpide), bronchi, lungs. Upper respiratory = nose, nasal cavity, pharynx + associated structures. Conducting zone: nose, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, terminal bronchioles. Filter, warm, moisten and conduct air to lungs. Respiratory zone: respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli. Site of gas exchange between air and blood. Area from which nerve impulses are sent to respiratory muscles. Consists of clusters of neurons located bilaterally in medulla oblongata + pons. When active => breathing rate more rapid. Chemoreceptors in medulla oblongata monitor levels of co2, o2, h. Pns also sensitive to changes of these levels in blood. We can alter our breathing because cerebral cortex has connections w/ respiratory. Nerve impulses from hypothalamus + limbic system also stimulate respiratory center center. Cartilaginous framework of the external nose = hyaline cartilage connected to. Unpaired septal nasal cartilage forms anterior portion of nasal septum.

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

k) ----------------------- shallow breathing using just the external intercostal muscles

l) ------------------ amount of effort required to expand the lungs and chest wall

m) ------------------- tidal volume + inspiratory reserve volume, usually about 3600 mL in males

n) ----------------- tidal volume + inspiratory reserve volume + expiratory reserve volume; usually about 4800 mL in males

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

r) ------------------ each gas in a mixture of gases exerts its own partial pressure

s) ------------------- sets basic rhythm of breathing

t) ------------------------ includes the pontine respiratory group
