This is the fourth slideshow in a series for Unit 4 VCE Environmental Science. It discusses the factors contributing to air pollution, the sources and sinks and the human and environmental health effects.
Any unwanted, disturbing or harmful sound that impairs or interferes with hearing, causes stress, hampers concentration and work efficiency or causes accidents called noise pollution.

13. Fysiologie: ventilatie
Compliantie (C)
Vermogen van het longweefsel om uit te zetten
Elasticiteit (R)
Vermogen om terug te keren naar de oude vorm
Voorbeeld:
COPD: hoge compliantie, lage elasticiteit
15. Fysiologie: ventilatie
Weerstand in luchtweg
Lengte
Viscositeit van lucht
Doorsnede van luchtwegen
Grootste weerstand in trachea en bronchi
Slijm verhoogt weerstand
20. Fysiologie: Gasuitwisseling
Regulering van de ademhaling
Chemoreceptoren
Perifeer: carotis en aorta
Centraal: medulla (CO2 in CSF)
PO2 te laag vaker en dieper ademhalen
PCO2 te hoog hyperventilatie
21. Fysiologie: Praktijk
Dode ruimte ventilatie
V/ Q > 1.0
Overschot aan ventilatie doet niet mee aan
gasuitwisseling
V
Q
Oorzaken:
Emfyseem, lage cardiac output
22. Fysiologie: Praktijk
Dode ruimte ventilatie
Anatomische dode ruimte
Luchtwegen die niet in contact komen met dode
ruimte
Fysiologische dode ruimte
Alveolair gas dat niet volledig met capillair bloed in
contact komt.
23. Fysiologie: Praktijk
Intrapulmonale shunt
V/Q ratio <1
Teveel bloed in de longen dat niet deelneemt aan
gasuitwisseling
Hypoxie
Q
V
Oorzaken:
Asthma, pulmonaal oedeem, pneumonie,
atelectase, gedeelte van long zonder embolie
