zat zat yang penting bagi tubuh

heii baru nemu dokumen waktu kelas 8 nih. yaa aku share aja deh siapa tau bisa berfungsi bagi kalian semua wahai yang membutuhkan ehehe. cekidot

Mineral

Mineral adalah zat kimia yang terdapat dalam bahan makanan yang diperlukan oleh tubuh kita. Mineral berfungsi sebagai zat pengatur sehingga proses metabolisme dalam tubuh berjalan normal. Hal ini disebabkan mineral dapat mempengaruhi berbagai proses yang ada di ddalam tubuh, misalnya ion kalsium atau zat kapur mempengaruhi proses pembekuan darah. Mineral berperan mengatur tekanan osmosis dalam tubuh dan memberi elektrolit untuk kerja otot dan syaraf. Kekurangan salah satu mineral dalam tubuh dapat menimbulkan penyakit yang disebut defisiensi mineral.

Mineral

Kalsium(Ca)

Sumber: Susu, telur, mentega, keju, kacang-kacangan, sayuran, dan buah-buahan.

Fungsi: -    Membentuk komponen tulanhg dan gigi

-      Membantu proses pembekuan darah

-      Mengaktifkan kerja otot dan memelihara fungsi otot dan jantung

Defisiensi mineral:  - Pembentukan tulang tidak sempurna

                              - Tulang rapuh (osteoporosis)

                              - Kekejangan otot

Fosfor(P)

Sumber: Susu, telur, daging, ikan, dan kacang-kacangan.

Fungsi: -  Membentuk komponen tulang dan gigi

-      Berperan dalam metabolisme zat-zat makanan

Defisiensi mineral: Jarang terkena defisiensi, tetapi jika kekurangan dapat menyebabkan: - Tulang dan gigi rapuh

          -  rakhitis

Natrium(Na)

Sumber: Garam dapur, daging, ikan susu, keju, telur, kentang, dan sayuran hijau.

Fungsi: -    Bersama dengan klor memelihara keseimbangan cairan tubuh

-      Membantu pengiriman pesan(implus) saraf dan kontraksi otot.

-      Mengatur permeabilitas sel-sel tubuh

Defisiensi mineral: Jarang terjadi, tetapi jika kekurangan dapat menyebabkan: nilai osmotik cairan ekstraseluler turun, kekejangan, dan kelelahan otot.

Klor(Cl)

Sumber: Garam dapur, daging,telur, dan susu

Fungsi:  - Mengatur (memelihara) keseimbangan cairan tubuh

Defisiensi mineral: Gangguan pencernaan dan kelelahan

Kalsium(Ca)

Sumber:  Ikan, daging, buah-buahan, dan sayuran

Fungsi: - Memelihara keseimbangan cairan tubuh

-      Membantu Kontraksi otot

Goldilocks and the Three Bears

nah yang ini ceritanya tuh aku dapet audiobook dari temen aku namanya ratri. terus waktu itu kan aku disuruh ikutan lomba story telling pas kelas 9 di salah satu SMA swasta islam di kawasan BSD yaudah aku bawain aja ini cerita. tapi butuh proses yang panjang. mesti dengerin bolak balik dari audio nya. jadi masih ada kata bahasa inggris yang salah. but, almost perfectly dah hehehe. well this is it

Goldilocks and the Three Bears

Once upon a time there were three bears. A Father Bear, Mother Bear, and Baby Bear. They lived in the house in the woods. Mother Bear had just prepared a large serving of porridge for her family. But it was much to hot to eat. “Let’s take a walk in the wood and wait for a porridge cool down” she adjusted. “Good idea” said father “We can work for a real appetite then “I’ll race to the big tree papa if you hurry!” squeal Baby Bear. So the Bear’s family left the core age end went on they way.

Goldilocks was a child who always wanted to have her own way.   Her mother often told her not get up from her bed untill she was called.

She needed strict rules like this one because she was so bold.

This one morning, the spring sun shone so brightly into her bedroom window and the birds were singing their mary songs. That she could not  resist the temptations to the dark of into the garden, and so she did , and continue the  cross the field where she found a lovely winding path where she had never been before.

Goldilocks follow the little path until it stops in front of the core age all covered with pretty spring flowers. She could not resist. She ran up to the house, to pick some of the flowers for her bedroom. When she know the step door was opened.  And again could not resist poking her head in. She did not knowed at the time but the Bear Family lived there.

“Oh what a delicious smell!” she exclaimed.  Then she saw the three blue bowls on the white table with spoon next to each one. Goldilocks want to the large bowl dugin the large spoon, reisted to the her lips,but found the porridge much to hot. Then she went over to middle size bowl. That was mother Bear’s. She picked up  the middle size spoon, raised that to her lips, but the porridge was much to cold. Finally, she went over to the bowl belonging to Baby Bear. She picked up the small spoon, and dug that into the porridge and there, the porridge were just right. So she ate it all up.

“I feel tired” she said. “I think I will rest in this chair”. There were three chairs lined up in the living room. She flown herself on to Father Bear’s chair. But it was much to high. “This one will be better” she talked. And she tried Mother Bear’s chair. But the arms were to high. “This one is just right” she said and she sat down on the Baby Bear’s chair. “It was perfect” . She rocked and rocked until suddenly the chair broken to small pieces. “Oopss” she said. But that the keep for looking around for placed to rest.

Goldilocks went to up stairs. In the bedroom she found three beds. First she tried the big bed but it was so big that she was almost very dened. Then she tried the middle bed but that one was much to hard. Then she tried a little bed and that one was just right. So Goldilocks had sain into the pillow and feel fast to sleep.

When the three bears came home, there were stradel  to see the mesain there home. “Who is been tasting my porridge?” exclaimed  Father Bear. “Who is been tasting my porridge?” ask mother Bear. “Who is been tasting my porridge?” squeack Baby Bear “And ate it all up” and he began to cry.

“ And who is been sitting in my chair?” crowded Father Bear. “And who is been sitting in my chair?” screamed Mother Bear. “And who is been sitting in my chair and broken all to pieces?” cried Baby Bear as he cried louder then before.

Then the three Bears went upstairs to the bedroom. “Who is been sleeping in my bed?” crowded the Father Bear. “And who is been sleeping in my bed?” screamed Mother Bear. “Who is been sleeping in my bed?” cried Baby Bear. “ Why here she is?”

Goldilocks woke up. She was very surprised to see the  three angry faces of the Three Bears. She was scared, so she jumped out of bed and ran all the way home.
