Unit 3. Digestive and Respiratory Systems

The human digestive system processes food that we eat. It is made up of multiple organs and glands that digest food, extract nutrients and later expel the waste products.
Here you can find some help to learn digestive system and digestion in english: a video1 ; another video 2 ;   Listening, diagram and some facts; MacGraw H video ;  Vocabulary explained. And at the end you can try with some tests: tests 1;  quiz 2 ;  quiz3;   quiz4;  quiz5.  Listening and flashcards.  Label the diagram , vocabulary games ,  Quiz games ,  another diagram .  And much more typing digestion quiz at Google.  Digestion song.
      Digestion. A window at the stomach. A French Canadian, Alexis St Martin, was accidentally shot in his side on June 6, 1822, Dr Beaumont treated him, and although St Martin recovered, he had an opening nearly 2cm across that led directly into his stomach. Dr Beaumont used him as human guinea pig to study works. St Martin lived with the hole in his stomach until he died in 1880, at the age of 82.This was the first documented study of digestion.
Nowadays we know digestion process quite well. We are studying digestion these days and you have to prepare next exam, reading unit 3 and doing exercises. You can find our class handouts, and presentation here: Vocabulary+exercises  ( and at Rosalia virtual class ) , digestion animation .
To those who like cooking I recomend a movie: "Julie & Julia" Nora Ephrom ( trailer )

UNITS 2 and 3 EXAM (just digestive system).  You have to be ready for the next exam, it will be on the first week of december. You have to read again units 2 and 3 (UP TO PAGE 47), look at the exercises and hand outs. The exam will have questions such as:  true and false,  multiple choice,  figures to fill in and tables or graphs to be interpreted. EXAM WILL NOT INCLUDE any respiratory system question!.

Unit 2. Food and nutrition

We are studying here the basics of human nutrition, its relationship with the care and development of our body, as well as its implications for health and illness.

How can you start?. 1. Check you understand the meaning of the words in blue;   2. Underline unknown vocabulary, look at the dictionary and copy these words your exercise book.

Premios Nobel

Estanse dando a coñecer estes días os Premios Nobel 2012. O Premio Nobel de Física é para os "pais" do Bosón de Higgs. Hai máis de 50 anos propuxeron un mecanismo para explicar a formación da materia no universo e que se desenvolveu dando o que hoxe se coñece como física de partículas. Os seus cálculos teóricos foron comprobados recientemente no CERN suízo. É polo tanto un premio e recoñecemento á ciencia europea.
Onte douse a coñecer tamén o Premio Nobel de Mediciña, foi para os científicos que estudiaron e xplicaron con detalle os movementos de vesículas (con moléculas) no interior da célula. É un momento adecuado para nos, que estamos estudiando a célula.
Por certo sabedes quen foi Alfred Nobel?. É o premio con maior prestíxio na comunidade científica a nivel mundial, e incluso o ranking de universidades se fai atendendo a estudiantes ou profesores "nobeles" que se relacionan con esas institutcións. En España tan so podemos citar a D Santiago Ramón y Cajal (estudiando as neuronas e a sinapse), e Severo Ochoa (éste último traballando en EEUU no ADN). Lamentablemente é un síntoma da ciencia española.
Os próximos anos veremos premios relacionados co cerebro, que é en este momento un reto para entender o seu funcionamento a nivel molecular.

Unit 1 The Human Body: cells, tissues and systems

Hi everyone, we are going to share this small web space, this blog will help you (to study, to enjoy and and to learn more). We have to use english at the classroom, it is hard, but we shall be proud at the end of the Year, I am sure.
Try to focus on words in black and blue at the book, repeat, write and try to understand them.
You should practice doing activities and work on Biology at least twice a week.
Stem cells are cells capable of regenerating one or more different cell types. Stem cells are will be part of medicine treatment of some serious illness such as Alzheimer or heart attack.
 To those who want to know more about these stem cells try here.
The Nobel Prize in Medicine 2013 is coming, you can write name/s and bring it to the class. Last year the Nobel Prize was awarded to Sir John B. Gurdon and Shinya Yamanaka for their discovery that "mature, specialised cells can be reprogrammed to become immature cells capable of developing into all tissues of the body. Does it sound like stem cells?.
Some videos:  Parts os an animal cell,  A cell rap (funny),  The inner life of the cell (animation)
Higher level, quite useful with transcript, very well explained (much better than mine!) Atour of the cell.   Types of human tissue.  Stem cells1  Stem cells2

As soon as we finish the Unit 1 we can do a quick test

The unit 1 test will be quite similar to the hand out I gave it to you with true/false and multiple choice questions, a cell table and a microscope figure.

The microscope names will be written on the exam, you have to find where the names are placed

You have to read the textbook unit 1 (more than once) and answer the exercises I told you ( they are written at the vocabulary hand out). Test questions can be related with the textbook questions

The vocabulary  hand out (I gave it to you) is a help to understand your textbook.

The unit 1 handout has also a figure explaining stem cells, look at it. Remember that  the textbook  exercises  must be done at  your exercise book.
