Natiijada casharka

Waxaan sharxi karaa sida sambabada aadanaha loo laqabsiiyay si ay u kordhiyaan xadiga is-weydaarsiga gaaska.

Hordhac

Soo dhawoow casharkan. Kahor intaadan daawashada billaabin, waa inaad hore u taqaanid qaabka iyo shaqada guud ee sambabada, iyo sida hawadu uga gasho dhiigga. Casharkani wuxuu ku saabsan yahay sifooyinka gaarka ah ee sambabada u leeyihiin si ay u kordhiyaan is-weydaarsiga gaaska (gas exchange).

Muuji qoraalka

The lungs are made up of tiny air sacs called alveoli. Gas exchange takes place between air in alveoli and blood in capillaries. There are millions of alveoli to increase the surface area of the lungs for gas exchange. The walls of the alveoli are one cell thick to create a short diffusion distance for gas exchange. The alveoli are surrounded by capillaries carrying blood, to maintain a concentration gradient for gas exchange.

Imtixaannada

1. Dooro jawaabta si sax ah u dhameysa jumladda: Gas exchange (is-weydaarsiga hawada) waa habka…
- …hawadu u gasho oo u soo baxdo sambabada iyadoo la neefsanayo oo la neefsadanayo.
- …loo isticmaalo sonkorta iyo oksijiinta si loo helo tamar nolosha.
- Jawaabta saxda ah:…oksijiinta iyo kaarboon laba-ogsaydhku (carbon dioxide) u kala gudbaan sambabada iyo dhiigga.
2. Jaantusku wuxuu muujinayaa nidaamka is-weydaarsiga hawada ee bini'aadamka. Xarafkee ee jaantuska ayaa matalaya bronchioles-ka (qanjidhada yaryar ee sambabada)?
- A
- Jawaabta saxda ah:B
- C
- D
- E
3. Jaantusku wuxuu muujinayaa nidaamka is-weydaarsiga hawada ee bini'aadamka. Xarafkee ee jaantuska ayaa matalaya alveoli-ga (alveoli)?
- A
- B
- Jawaabta saxda ah:C
- D
- E
4. Markaxa diffusion-ka, dhaqdhaqaaqa shabakadda ah ee walxaha (particles) waa...
- Jawaabta saxda ah:...meelaha ay ku badan yihiin una socdaan meelaha ay ku yar yihiin.
- ...meelaha ay ku yar yihiin una socdaan meelaha ay ku badan yihiin.
- ...inta u dhaxaysa meelaha ay isku qiyaas yihiin.
5. Waa kuwee kuwan soo socda ay yihiin astaamaha faafitaanka (diffusion)?
- Jawaabta saxda ah:Walxaha ayaa si aan kala sooc lahayn u dhaqaaqaya.
- Waxay u baahan tahay tamar ka timaadda neefsashada (respiration).
- Waa hab aan firfircoonayn (passive).
- Marka walxuhu si siman u faafaan, way istaagaan inay dhaqaaqaan.

1. Alveoli waxay ka mid yihiin heerka ururinta ee noocee ah?
- xubin (organ)
- unug (cell)
- Jawaabta saxda ah:nud (tissue)
- nidaamka xubnaha (organ system)
- moleekul (molecule)
2. Dooro jawaabta si sax ah u dhameysa jumladdan: gidaarada alveoli-ga waxay ka kooban yihiin hal unug oo dhumucdiisu tahay si loo…
- Jawaabta saxda ah:sameeyo masaafo gaaban oo diffusion (faafin) ah oo loogu talagalay in oksijiin iyo kaarboon dioxide (carbon dioxide) lagu beddelo.
- kordhiyo bedka (surface area) ee sambabada si gaas lagu beddelo.
- siiyo heerka xoojinta (concentration gradient) ee u dhexeeya alveoli-ga iyo xididka dhiigga (capillary).
