PUSTI ODAM – EHSOSI MUHITI ZIST TAVASSUTI PUST

Odam tavassuti pust garmi, khunuky, dardro his mekunad. Puste, ki badani odamro mepushonad, 1/20 qismi vazni umumiro tashkil medihad. Irtiboti az hama kalo ni organizmi odam bo muhiti zist tavassuti pust surat megirad.

Dar pust, makhsusan dar angushtoni daston, kafho, labho va kafi poyho tedodi ziyodi nugi torhoi asabi mavjud meboshand. Az in ru, onho hama hassos meboshand.

Ba pust chahor navi ehsos khos meboshand: ehsosi dard, ehsosi tamos, ehsosi khunukiyu garmi. Azbaski dar pust bisyor ranghoi khungard, gadudhoi araqin hastand, vay naqshi buzurgero dar tanzimi harorat mebozad.

Az hisobi shuoi garmy va bukhorshavii araq 80% garmidihi tavassuti pust surat megirad. Hudi pust garmiro nachandon khub intiqol medihad. Vay garmiro az khuni ba on jorishavanda, megirad. Garmidihi bo tagyir yoftani surati gardishi khun, ki tavassuti fishurdashavi va tavsiai ragho muayyan meshavand, tanzim meyoband.

Dar qismathoi gunoguni badan harorat gunogun meshavad.

Tavri misol,

Kafhoi dast – 32,2°S,

Peshoni – 33,4° S,

Qismati boloii qafasi sina – 39,8°S,

SHikam – 31,1 °C,

Gardan – 34° S,

Zeri bagal – 36,7°S,

Kafi poy- 30,2°S.

Darorati badani odamro dar zeri bagalho mesanjand. Az in ru, harorati mutadil 36,7°S shumorida meshavad. YAke az khususiyathoi asosii pusti kudakon va navrason in beshtar budani sathi nisbii pusti onho nisbat ba sathi nisbii pusti odami bolig ba shumor meravad. Ba 1 kg vazni odam chunin maydoni sathi pust baro­bar meoyad:

Kudaki navzod – 704 sm2

Kudaki 1-sola – 528 sm2

Kudaki b-sola – 456 sm2

Kudaki 10-sola – 423 sm2

Navrasi 15-sola – 378 sm2

Odami bolit – 221 sm2

Az in ru, dar muqoisa bo garmidihii odamoni bolit, garmidihii kudakon nisbatan beshtar meboshad. Gadudhoi araqi araq ikhroj mekunand. SHumorai gadudhoi araqi to ba 2-3,5 million rasida, miqdori on baroi har yak odam gunogun meboshad. Araqkunii organizm ba miqdori gadudhoi araqi vobasta ast. Gadudhoi araqy dar ba­dan yakson qaror nadorand. Onho dar kafho, zeri bagal va kafi poho bisyor buda, dar pusht, soku zonuho kam meboshand.

YAkjo bo araq, az organizmi odam mavodhoi sershumor, namak va hamchunin karba­mid, yane partovi mubodilai safeda dar organizmi odam va bisyor hayvonho, khorij meshavand. Az odami miyonasol dar yak shabonaruz 400-600 ml araq , hamchunin 40 g namak, 10 g azot khorij mekunad. Pust vazifahoi gunogunro ijro menamoyad. Vay organizmro az tasiroti mekhaniki( fishor, molish, kharosh va jarohatho) muhofizat menamoyad. Dangomi harorati mutadil +18°S – +20°S tavassuti pust ba organizm 1,5% kislorod vorid meshavad. Hangomi kori jismony va harakat voridshavii kis­lorod ba organizm 45 barobar ziyod meshavad. Damchunin pust organizmi insonro az shuohoi ultrabunafshi oftob hifz menamoyad.

Tahti tasiri shuohoi ultrabunafsh vitamini D paydo meshavad, ki on az bemorii rakhit muhofizat mekunad. Pusti tozai jarohatnadida moneai vorid shudani mavodhoi kimiyovi ba organizm megardad.

Toza nigoh doshtani pust faoliyati mutadili organizmro tamin mekunad.

Iflosi dar pust binobar az had ziyod shudani ravgani pust va qabati boloii pust ba vujud meoyad. Dar in mavrid, surokhihoi pust basta shuda, zud yarachaho pay­do meshavand. Hangomi iflosshavy khorishi pust va sharoit baroi vorid shudani infeksiya ba organizm paydo megardad. Hatto tavassuti dastoni noshusta metavon ba bemorihoi sershumori siroyaty mubtalo shud. Pust hangomi shustan bo sobun bo obi khunuk toza nameshavad.

Sobun pustro muloim karda, baroi rahoi az khujayrahoi murda kumak mekunad.

Rioya kardani qoidahoi gigienai shakhsi hangomi nigohubini pust baroi peshgi- rii bemorihoi pust kumak merasonad.

Suporish

Vobasta ba sinnu soli khus va vazn sathi nisbii pusti badani khudro muayyan kun. Tavri misol, agar tu 10-sola hasti va vazni tu 30 kg ast, pas tu metavoni sathi nisbii pusti badani khudro badin tavr muayyan karda boshi : 423 -ZOkg = 12690 sm2.
