respiratory system 4

normal quiet breathing moves approximately _ of air into and out of the lungs with each breath.

respiratory volume is called

the amount of air that can be taken in forcibly above the tidal volume is the _, which is around _

the amount of air that can be forcibly exhaled beyond tidal expiration is called _, and is approximately _

about 1,200 ml of air still remains in the lungs and can not be expelled. it is important because it allows gas exchange to go on continuously even between breaths and helps to keep the alveoli open

respiratory capacities are measured with

result of reflex activity, but some may be produced voluntarily

nonrespiratory air movements CSCLHY

taking a deep breath, closing glottis, and forcing air superiorly from lungs against glottis. then, glottis opens suddenly, and a blast of air rushes upward. it acts to clear the LOWER respiratory passageways.

expelled air is directed through nasal cavities. the uvula becomes depressed and closes oral cavity off from pharynx, routing air through nasal cavities. it clear UPPER respiratory passageways.

inspiration followed by release of air in a number of short expirations. primarily an emotionally induced mechanism

essentially same as crying in terms of air movements produced. also an emotionally induced response

sudden inspirations resulting from spasms of diaphragm; initiated by irritation of diaphragm or phrenic nerves, which serve diaphragm. the sound occurs when inspired air hits vocal folds of closed glottis

very deep inspiration, take with jaws wide open; ventilates all alveoli

respiratory tree produces two recognizable sounds that can be picked up with a _

produced by air rushing through the large respiratory passageways (trachea and bronchi)

occurs as air fills the alveoli, are soft murmurs that resemble a muffled breeze

bubbling sound

whistling sound

in _, blood delivers oxygen to body tissues and picks up carbon dioxide

most oxygen attaches to hemoglobin molecules inside the rbc to form _

CO2 is _ more soluble in plasma compared to oxygen

most cO2 is transported in plasma as _, which plays very important role in buffering blood pH.

inadequate oxygen delivery to body tissues is called _

is odorless, colorless gas that competes vigorously with oxygen for the same binding sites on hemoglobin

hemoglobin binds to CO more readily than to oxygen, carbon monoxide is a very successful competitor - so much so that it crowds out or displaces oxygen
