He aha ka pression osmotic

'O ka Osamosis ka ho'ohaunaha like'ole o nā meaola pa'ama ma o ka membrane semi-impermeable mai ka mea i ho'omo'ulua'ole'ia i ka hopena i'oi aku ka hopena. 'O ka membrane ma'amau'ole kahi mea e ma'alahi i nā kinai uila a me ka lepo'ole i nā mea lepo i'oki'ia i loko. Ma ka ho'ākāka 'ana, ka osmotic puʻe - ka mea, o ka hydrostatic puʻe, i ke noi o ka a hiki i ka pāʻoihana mea, e hooki aku i ka maholahune o na (particles), oa osmosis.

Kauhola ka Osmosis ma ke'ano. He'ano kūlohelohe ia o nā meaola āpau. Ho'opilikia ke ala Osmotic inā ho'oka'awale'ia nā kūmole e kahi membrane semipermeable. Eia kekahi la'ana, e lawe i nā wai i loko o nā pūnaewele a me ka space intercellular. 'O ke'ano,'oi like ka extracellular a me ka ho'ohemo osmotic intracellular. Akā, inā interstitial loli haalele i ka wai puʻe , piʻi pū ma loko. Ma lalo o ka ho'onāukiuki o ka nui o ka pēmole koi, hiki i ka wai mai nā pūmoku e ho'omaka i ka ho'oka'awale'ana i kahi o waena. E ho'opau wale ka wehewehe wale nō i ka ho'ohālike'ia o nā ho'okomo.

He aha ka mea e ho'oholo ai i ke kaumaha osmotic

'O ka hopena o ka pulupulu ma muli o ka nui o nā mea'ele'ele i ho'one'e'ia i loko o ka pu'upu'u ho'okahi. Hiki i kēia mau mea ke hana i nā molekino, nā ion a me nā mea'ē a'e colloidal. Hiki ke'ōlelo'ia, he pili ka hopena osmotic o ka hopena i ka ho'onui'ia o nā mea'āpana a pau e hana wikiō, ma kēlā me kēia pu'upu'u. 'A'ole ia e hilina'i'ia ma nā'ano kinikona o ka mea ho'olimalima a ho'ohehe'e'ia nā mea i loko.

ʻepekema, ua loaʻa i ka osmotic puʻe nonoi aku nei ka mea ia kānāwai, e like me ke kinoea puʻe. Hiki ke ana'ia me nā mea kani i kapa'ia'o osmometers. He'ano'ano manometers lākou. Ho'ohana kēia mau mea i nā membrane non-impermeable o nā holoholona a me nā kumu hana. Puʻe ana hōʻike i ka pololei kaukaʻi maluna o ka lehulehu o ka pāʻoihana.

Ke kānāwai o osmotic puʻe, e wehe ae van Hoff, hoʻopaʻapaʻa i kona mea heluna hapauuku like i kēia manaʻo koikoi, a ua hāʻawi ai i ka waiwai o ka pāʻoihana, i ma ka ua mahana, maikaʻi kinoea, a me ka proviso i kona leo e like me ka buke o ka pāʻoihana.

Ua ho'ākāka'ia ke kānāwai e ka hoohalike: p = i CRT

i- waiwai isotonic kaʻi lau waiwai ;

C ka mahele o ka hopena, i ho'ākāka'ia i nā moa;

'O R ka waiwai o ke ka'awa holo'oko'a mau;

'O T ka thermodynamic temperature.

'O ke kumukū'ai o ka kaomi koi no nā meaola ola

'O ke'ano o ka Osmosis ka mea hihiu, no ka mea, he mau membena like'ole o nā mea kanu a me nā meaola holoholona ka wai kūpono i ka wai a hiki'ole i nā mea'ē a'e. Ma nā mea ola, ma ka palena o ke kele a me ka wai o intercellular, ke hana mau ka hana osmotic. Ho'omaopopo ia i ka ulu'ana o nā mea'ai a me ka wai mai ka honua a hiki i nā lau o nā mea kanu a me ka piho o nā mea kanu, ka hana nui o nā pūnaewele.

Ho'ohui'ia nā'olu'olu e like me ka'ōlelo osmotic like isotonic. 'O ka po'e i'oi aku ka pihi, ua kapa'ia he hypertonic,'o ka hypotonic ka lalo.

'O ka wīwī kaomi i loko o ke koko o ke kanaka, he 7.7 kek. Hiki i nā kānaka ke hopohopo iki. 'O kēia la'ana, pili i ka make'ana i ka lawe'ana i ka mea'ai. 'O ka'ōhū o ka waena me ka mumuna e ulu ana ma muli o ka pi'i'ana o ka pēmole osmotic ma ka pūnaewele o ka mumū.

'O ka'ike i nā kānāwai o ka ho'oikaika kaumaha i ka lā'au lapaau e pono i ka wā e ho'okō ai i nā hana lapa'au. No laila, ua'ike nā kauka no ka hana'ana i loko o ke kino, hiki ke ho'ohana wale i ka plasma blood isotonic 0.9% NaCl solution. 'A'ole ia he kumu no ka huhū o ke kino. Eia ke'ano, ho'ohana'ia ka 3-5% NaCl i mea e ho'omāmā loa ai i nā ma'i'eha o nā mea'ano a me ka pā.

'O ka'ike i nā kānāwai o ka osmosis'a'ole kūpono wale nō i nā lā'au lapa'au a me ka biology. Inā'ole,'a'ole e hiki i nā'ano hana like'ole ke hana me ka'ole o ka'oihana a me ka ikaika.
