Bio F4 Bab 8.1

Jenis Sistem Respirasi

QuestionAnswer
Mengapakah Amoeba sp tidak memerlukan struktur respirasi yg khas&jelaskan bagaimana Amoeba sp melakukan respirasi??? Mempunyai nisbah jumlah luas permukaan kpd isipadu yang besar utk prtukaran gas respirasi scra resapan
Senaraikan ciri2 pnyesuaian struktur respirasi utk prtukaran gas yang efisien bg organisma brsaiz besar 1>Nisbah jumlah luas perm. kpd isipadu yg besar=prtukarn gas cekp 2>Struktur respirasi nipis,stebal 1 sel=memudhkn resapan gas respirasi brlaku 3>Perm.struktr rspirasi yg sntiasa lmbap=mbenarkn gas respirasi mlarut di dlmnya 4>Dlengkapi jaringn kap drh
Sistem pernafasan serangga ialah sistem trakea, huraikan fungsi2 sistem tersebut... Spirakel,liang kcil pd toraks&abdomn-mbolehkn udara masuk ke dlm sistm tiub udara=sistem trakea~>Trakea brcbang mbentuk salur yg halus=trakeol=permukaan respirasi
Terangkan ciri2 trakeol yg membolehkan prtukaran gas berlaku dengan cekap 1)Bil. Trakeol yg bnyk-jumlah luas perm. yg besar utk prtukaran gas 2)Dinding trakeol=nipis&lembap->mbolehkn gas O2 mresap masuk ke dlm sel&gas CO2 mresap kluar dgn cepat
Apakah fungsi kantung udara pada serangga??? Kantung berisi udara mempercepatkn pnghantaran gas respirasi smasa pergerakan bdn yg cergas
Jelaskan struktur respirasi ikan... Insang->trdiri drpd barisan filamen yg disokong oleh lengkung insang
Terangkan ciri2 filamen yg membolehkan pertukaran gas repsirasi berlaku dengan cekap 1>Filamen bnyk unjuran nipis&pipih=lamela~>Bil. filamen&lamela yg bnyk mberi jumlah luas perm. yg besar utk proses prtukaran gas cekap 2>Membran lamela nipis 3>Kapilari darah yg bnyk=memudahkn presapan&pngangkutan O2&CO2
Jelaskan struktur respirasi katak 1>Kulit, dlm keadaan kurang aktif katak mnggunakn kulit 2>Peparu
Huraikan ciri2 kulit katak yg meningkatkan kecekapan pertukaran gas respirasi 1)Kulit yg nipis&sngt telap trhdp gas respirasi 2)Kulit yg lembap mbenarkn gas respirasi mlarut ke dlmnya 3)Di bwh kulit, trdpt bnyk jaringan kapilari darah utk mngangkut gas respirasi
Huraikan ciri2 peparu katak yg meningkatkan kecekapan pertukaran gas respirasi 1>Perm. paru katak brlipat2-mnambahkn jumlah luas perm. bg pertukaran gas 2>Membran nipis-memudhkn resapan gas respirasi 3>Dinding peparu sntiasa lembap-mbolehkn gsa rspirasi mlarut ke dlmnya 4>Paru kaya dgn jaringan kapilari drh utk mngangkut gas cpt
Apakah struktur respirasi manusia? Alveolus
Jelaskan ciri2 prtukaran gas respirasi yang cekap bagi manusia... 1>Bil.alveolus bnyk mnyediakan jumlah luas perm. yg besar utk presapan gas respirasi 2>Dinding alveolus sntiasa lmbap-O2&CO2 blh mlarut dgn mudah 3>Dlingkari oleh jaringn kapilari drh yg bnyk-mempercpatkn presapan gas respirasi 4>Dnding alv nipis=1 sel
Ramalkan apa yang akan berlaku trhadap ikan yang insangnya terkoyak akibat tersangkut pada jaring Mngurangkan jumlah luas perm. utk prtukaran gas efisien~Kmungkinan ikan akan mati sbb kekurangan O2

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
