Respiratory system
What is the sequence of events during each normal respiratory cycle?
Pressure difference leading to lung volume change and air flow

Mass flow
What is the main factor in the preservation of human life related to the mechanics of breathing?
Adaptability of the cardio-pulmonary system
What happens when there is a fall in air pressure?
Alveolar spaces expand and air enters the lungs (inspiration)

Expiration

It increases the breathing rate
Which factor is responsible for the flow rate of air during breathing?
Magnitude of the pressure difference
What is the primary mechanism through which air rushes in and fills the lungs during inspiration?
Contraction of diaphragm
How does heavy exercise affect a person's breathing rate?
It increases
Study Notes
Metabolic syndrome is a cluster of metabolic abnormalities that increases the risk of developing cardiovascular disease, type 2 diabetes, and stroke[100][101][102][103][104][105][106][107][108][109][110][111][112][113][114][115][116][117][118][119][120][121][122][123][124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139][140][141][142][143][144][145][146][147][148][149][150][151][152][153][154][155][156][157][158][159][160][161][162][163][164][165][166][167][168][169][170][171][172][173][174][175][176][177][178][179][180][181][182][183][184][185][186][187][188][189][190][191][192][193][194][195][196][197][198][199][200][201][202][203][204][205][206][207][208][209][210][211][212][213][214][215][216][217][218][219][220][221][222][223][224][225][226][227][228][229][230][231][232][233][234][235][236][237][238][239][240][241][242][243][244][245][246][247][248][249][250][251][252][253][254][255][256][257][258][259][260][261][262][263][264][265][266][267][268][269][270][271][272][273][274][275][276][277][278][279][280][281][282][283][284][285][286][287][288][289][290][291][292][293][294][295][296][297][298][299][300][301][302][303][304][305][306][307][308][309][310][311][312][313][314][315][316][317][318][319][320][321][322][323][324][325][326][327][328][329][330][331][332][333][334][335][336][337][338][339][340][341][342][343][344][345][346][347][348][349][350][351][352][353][354][355][356][357][358][359][360][361][362][363][364][365][366][367][368][369][370][371][372][373][374][375][376][377][378][379][380][381][382][383][384][385][386][387][388][389][390][391][392][393][394][395][396][397][398][399][400][401][402][403][404][405][406][407][408][409][410][411][412][413][414][415][416][417][418][419][420][421][422][423][424][425][426][427][428][429][430][431][432][433][434][435][436][437][438][439][440][441][442][443][444][445][446][447][448][449][450][451][452][453][454][455][456][457][458][459][460][461][462][463][464][465][466][467][468][469][470][471][472][473][474][475][476][477][478][479][480][481][482][483][484][485][486][487][488][489][490][491][492][493][494][495][496][497][498][499][500][501][502][503][504][505][506][507][508][509][510][511][512][513][514][515][516][517][518][519][520][521][522][523][524][525][526][527][528][5
