ʻO kadiffusion a me osmosis he phenomena i hōʻike ʻia e ka hoʻokaʻawale ʻana o nā molaki o kahi kino i kahi kino ʻē aʻe e launa me kēlā mua a i hoʻokaʻawale ʻia paha, akā ma o ka membrane semiplasmic. ʻO kēia mau mea hiki ke kūpono i ka mea e wehe i ka mahele ma waena o nā kaʻina hana ʻelua.

He aha ka hoʻolele leo?

ʻO ia ka pāhola kū kekahi intermixing o nā mole, ma muli o kahi neʻe e hoʻokuke i kā lākou Ikehu Kinetic. Hoʻohui nā kino a laila hāʻawi ʻia nā mole, i kahi hanana i wehewehe ʻia e ka kumumanaʻo kinetic o ka mea.

Kū kēia neʻe i kekahi o nā mokuʻāina o ka mea, akā ʻike maʻalahi ʻia i ka hihia o wai. ʻO ke ʻano o ka neʻe ʻana i ka hoʻokumu ʻana i kahi hui like o nā ʻano ʻelua mole.

ʻO ka ʻepekema ʻO Adolf fick i hoʻokumu ʻia i ka makahiki 1855 kekahi mau kānāwai e kau ana i kona inoa, a wehewehe i nā hihia like ʻole o ka diffusion o ka mea i loko o kahi meahana i ka wā mua ʻaʻohe kaulike. Pili kēia mau kānāwai i ka nui o ka wai o nā mole i ka ʻokoʻa o ka hoʻokaʻina ma waena o nā media ʻelua i hoʻokaʻawale ʻia e ka membrane, ko lākou coefficient diffusion a me ka permeability o ka membrane.

A laila, e hōʻike ʻia kekahi mau hihia o ka diffusion o ke kelepona.

Nā laʻana o ka diffusion

1. ʻO ka hele ʻana o ka oxygen ma ka alveoli pulmonary.
2. Nā impulses nerve, kahi e hoʻopili ai i nā iona sodium a me potona ma o ka membrane o nā axons.
3. Inā lawe ʻia kahi paʻa diffuser o ʻelua mau metala i hoʻopili ʻia ma waena o ko lākou alo, a lawe ʻia ka mahana ma lalo o ka pae hoʻoheheʻe, e hōʻoia ʻia ua loli ke ʻano: ua hoʻoheheʻe ʻia nā ʻenela nickel i ke keleawe.
4. ʻO ka hoʻomehana ʻana a me ka loli ʻana o ke kīʻaha kope ke hoʻohui ʻia kahi mahele maikaʻi o ka waiū anuanu.
5. Ke komo ʻana o ka glucose i nā hunaola ʻulaʻula, e puka mai ana mai ka ʻōpū.
6. I ka lua wai, aia ka liʻiliʻi o ka diffusion o ka wai o ka muliwai e kahe ana ma luna o ka wai kai.
7. Inā ʻoe e hoʻokomo i kahi puna o ke kō i loko o ke kīʻaha wai, hoʻolaha nā mole moleka i loko o ka wai.
8. Hiki ke ʻike ʻia ka diffusion o nā kinoea ke komo kahi mea ʻala i kahi pani, a ʻike koke kēlā me kēia i ka ʻala. Pēlā nō ke puhipaka kekahi i loko o ka hale.

He aha ka osmosis?

ʻO ke ʻano nui o ka membrane semi-permeable e hāpai ai i ke kaʻina o osmosis ʻae ia i ka hele o ka mea hoʻoheheʻe, akā ʻaʻole ka mea hoʻoheheʻe: loaʻa nā pores o ka nui mole i hāʻawi i kēia mau ʻano.

I kēia ala, ʻike ʻia kēlā ka mea hoʻoheheʻe e hele i waena o ka membrane i ke kuhikuhi o ka hopena i ʻoi aku ka kiʻekiʻe ma luna, kahi e hoʻopau ai i ka hana ʻana i ka nui o nā mea hoʻoheheʻe e hoʻonui i ka ʻāpana nui a hoʻoliʻiliʻi i ka ʻāpana liʻiliʻi liʻiliʻi. He hana kēia i hana hou ʻia a hiki i ke kaomi hydrostatic kaupaona i ke au.

No ka mea nui ia?

ʻO ka solubility o ka mea hoʻoheheʻe i loko o ka mea hoʻoheheʻe a me ke ʻano o ka membrane e hoʻohana ʻia ai nā kumu kumu e hoʻoholo ai i ka maikaʻi o ke kaʻina osmotic: ʻo ka mea i kapa ʻia ʻo 'solubility' e hoʻoholo ʻia e nā mea paʻa kemika i hōʻike ʻia i kēlā me kēia ʻāpana i ka hopena. .

ʻO ke kaʻina osmotic kahi mea nui i nā hana olaola kahi o ka wai ka mea hoʻoheheʻe, keu hoʻi i kēlā mau hana i mālama ʻia i ka mālama ʻana i ka wai a me ke kaulike electrolyte i nā mea ola, e hoʻoponopono ana i nā pae o ka wai i loko o ka pūnaewele a i ʻole ke kino i ka nui. me ka ʻole o kēia kaʻina hana, ʻaʻole hiki ke mālama ʻia ka wai a me ka lawe ʻana o ka nutrient.

Nā laʻana o ke kaʻina osmosis

1. Hoʻokomo nā mea ola pākahi e noho ana i ka wai hou i ka nui o ka wai ma o osmosis.
2. ʻO ka omo ʻana o ka wai e nā aʻa i nā meaola mea kanu, e ʻae ai i ka ulu ʻana, hana ʻia ma o kahi hanana o kēia ʻano.
3. ʻO ka loaʻa ʻana o ka wai mai nā hunaola epithelial e ka ʻōpū nui he hana ia.
4. ʻO ka hoʻokolohua osmosis maʻamau ka hoʻokaʻawale ʻana i kahi ʻuala, e waiho ana i kahi kō me ka wai ma kekahi wēlau, a me kahi pā me ka wai ma kekahi ʻaoʻao. Hana ka ʻuala ma ke ʻano he membrane, a ma hope o kekahi manawa e ʻike ʻia ka hopena o ke kō i kēia manawa ʻoi aku ka wai.
5. ʻO ka hormone ADH e ʻae ai i ka reabsorption o ka wai e ka ʻohi hōʻiliʻili i nā puʻupaʻa.
6. ʻO ka hoʻopau ʻia ʻana o ka mimi hoʻoheheʻe loa a ka iʻa e kipaku aku ai i ka wai kiʻekiʻe loa me ka liʻiliʻi loa o ka paʻakai.
7. Hana ʻia ka hoʻopau ʻia ʻana o ka wai ma o ka hou i loko o ka poʻe ma o osmosis.
8. ʻO nā kānana e hoʻomaʻemaʻe i ka hana wai me osmosis, ʻoiai ua hana ʻia lākou me kahi mea e ʻae ai i ka hele o ka wai, akā ʻaʻole nā ​​mole nui.
