They are also adapted to protect the organism from the invasion of pathogens along those surfaces. ‘Provide adequate ventilation with window fans when using adhesives, as some are toxic.’ ‘Provide adequate ventilation to maintain indoor humidity levels between 30-60 %.’ ‘The most effective way to prevent it is by providing adequate ventilation.’ ‘Dai followed her gaze to the ventilation shaft above them then looked at Cooper.’ When air reaches alveoli, diffusion occurs and PO2 falls further, as PCO2 increases. There is a right and left lung. Graduate. VENTILATION AND PERFUSION I. 16. Definitions covering ventilation and the flow of air into and out of a space include: Purpose provided (intentional) ventilation: Ventilation is the process by which ‘clean’ air (normally outdoor air) is intentionally provided to a space and stale air is removed.

Medium flows past gas exchange surface in an unpredictable pattern. Lan. 1st ed. Fishes live deep inside the water and so they use oxygen present in the water to breathe. Exercise and smoking both affect the lungs and circulatory system. The ribs, intercostal muscles and diaphragm all play important roles in ventilation (breathing). See also respiration (def. Total Cards. Ventilation, or breathing, is the movement of air through the conducting passages between the atmosphere and the lungs.The air moves through the passages because of pressure gradients that are produced by contraction of the diaphragm and thoracic muscles.. This may be accomplished by either natural or mechanical means. Ventilation is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used to control indoor temperature, humidity, and air motion to benefit thermal comfort, satisfaction with other aspects of indoor environment, or other objectives. Air enters the respiratory system through the mouth and the nasal cavity, passing through the pharynx then larynx (where sounds are produced for speech) and finally the trachea which enters the chest cavity. CONTINUE SCROLLING OR CLICK HERE FOR RELATED SLIDESHOW The total ventilation rate is calculated as the positive flow of air into the microclimate integrated over the oscillation period (ζ) per unit area of the clothed surface as follows: 7.10a m ˙ a = 1 2 πRLτ ∫ o τ ∫ 0 L ∫ 0 2 π max 0, m ˙ a Y R d θ d x d t kg / s. m 2.
