solutions graded A+ updated
23/ paranasal sinuses and 3 pharynx’s - correct answer ✔✔frontal, sphenoid maxillary sinus
3 pharynx: nasopharynx, oropharynx, laryngopharynx
9 functions of the respiratory system - correct answer ✔✔1. gas exchange: o2 uptake/co2
release
2. conditioning inspired air: warm/moisturize and filter particles
3. secretion of mucus (clear debris)
4. filter small emboli from the blood
5. secrete surfactant and ACE
6. acid base balance of blood: co2/hco3 buffering
7. vocalisation at the larynx
8. olfaction
9. heat loss
what is physiological dead space - correct answer ✔✔alveolar and anatomical dead space
air movement within conducting airways vs alveolar airways - correct answer ✔✔convection vs
diffusion
what synthesizes surfactant? - correct answer ✔✔type 2 alveolar pneumocytes
what prevents alveolr collapse due to ST - correct answer ✔✔pores of kohn/ canals of lambert
, 2 blood supplies for lungs - correct answer ✔✔pulmonary and bronchial artery
why is there increase compliance in pulmonary circulation - correct answer ✔✔pulmonary
arteries and arterioles are thinner and have larger diameter when compared to systemic
circulation. there is less resistance as a a result and more compliance
what is the effect of having increased compliance - correct answer ✔✔1. con contain large V of
blood
2. reduces pulse pressure
3. distensibility protects against edema
24/ muscles for inspiration: - correct answer ✔✔for quiet: diaphragm and lateral external
intercostals
accessory muscle for forced: trapezius, sternocleidomastoid, scalenes, upper respiratory tract
muscle
muscles for expiration - correct answer ✔✔quiet: is passive
forced: lateral internal intercostals, rectus abdominus, neck and back muscles, external and
internal obliques, transversus abdominus
what does the pleural fluid allow for? - correct answer ✔✔lungs to slide over chest wall. sticks
lungs to chest wall
what counters elastic recoil of alveoli and keeps alveoli open - correct answer ✔✔interpleural
pressure
