Do  Now  1.  Take  out  HW  due  today—Science  in  the  

News  Report  on  the  Flu    2.  Complete  the  Do  now  prompt  On  your  notes  

sheet.    3.  When  done—begin  vocabulary  grid  for  the  

next  unit.      

Do  Now  Answers  

Use  the  following  words:  lungs,  trachea,  bronchi,  diaphragm,  respiratory  system.    Last  week,  we  made  a  model  of  the  respiratory  system.  The  boLom  glove  of  the  model  is  the  diaphragm.  The  straws  are  the  trachea  and  bronchi.  The  glove  fingers  are  the  lungs.  When  we  pulled  on  the  boLom  glove,  the  lungs  filled  with  air.    

Your Learning Goal: �Students will analyze the structure and function of the respiratory and

circulatory systems through notes, videos, and a worksheet.�Standard: �5.  b.  Students  know  organ  systems  funcNon  because  of  the  contribuNons  of  individual  organs,  Nssues,  and  cells.  The  failure  of  any  part  can  affect  the  enNre  system    

 6.  j.  Students  know  that  contracNons  of  the  heart  generate  blood  pressure  and  that  heart  valves  prevent  backflow  of  blood  in  the  circulatory  system.   �

INTRODUCTION  TO  CIRCULATORY  SYSTEM    The  circulatory  system  is  responsible  for  transporNng  oxygen  and  nutrients  throughout  the  body.  

diseasespictures.com    

The  circulatory  system  works  with  the  respiratory  system  to  bring  oxygen  into  the  body  and  get  rid  of  carbon  dioxide.  

www.fi.edu    

The  circulatory  system  has  three  main  parts:  1.  Blood  2.  Blood  vessels  3.  The  heart   science.howstuffworks.com

BLOOD    The  main  funcNon  of  blood  is  to  deliver  nutrients  and  oxygen  to  cells  all  over  the  body,  and  take  away  waste  products  like  carbon  dioxide.

Blood  is  made  of    different  substances:  1.   Plasma  2.   Red  Blood  Cells  3.   White  blood  cells  4.   Platelets      

www.pennmedicine.org  

1.  Plasma    A  fluid  part  of  your  blood  that  is  90%  water  and  10%  proteins,  nutrients,  and  sugars.      

www.wisegeek.org  -­‐  

2.   Red  Blood  Cells    Jelly-­‐  Donut  shaped  cells  in  your  blood.  They  contain  a  chemical  called  hemoglobin  that  helps  carry  oxygen  to  cells  and  carbon  dioxide  away.      

www.medterms.com  

3.  White  Blood  Cells  These  cells  make  up  a  Nny  porNon  of  your  blood.  They  are  a  part  of  your  immune  system,  which  helps  fight  against  invading  bacteria  and  viruses

4.  Platelets    These  are  also  a  Nny  part  of  your  blood.  Platelets  are  Nny  parNcles  that  help  prevent  blood  loss.  When  you  bleed,  your  platelets  slow  down  the  bleeding  by  clohng,  or  “bunching  together”   www.fi.edu  

BLOOD  VESSELS—3  types    1.   Arteries—thick,  

muscular  vessels  that  carry  oxygen-­‐rich  blood  away  from  the  heart  and  to  the  rest  of  the  body.  

 They  branch  smaller  and  smaller  as  they  get  further  away  from  the  heart.   8.5  Artery,  Vein,  &  Capillary  Structure  

losrios-­‐training.org  

2.  Capillaries—extremely  thin  and  Nny  blood  vessels  that  allow  oxygen,  carbon  dioxide,  and  nutrients  to  pass  through  its  walls.  They  are  only  one  cell  thick.    They  join  arteries  and  veins  together.  

8.5  Artery,  Vein,  &  Capillary  Structure  losrios-­‐training.org  

3.  Veins—thinner  vessels  that  carry  oxygen-­‐poor  blood  from  the  rest  of  the  body  back  to  the  heart.      They  contain  valves  to  prevent  blood  from  flowing  backwards,  since  they  are  further  away  from  the  heart.    The  skeletal  muscle  surrounding  the  veins  help  move  the  blood  forward.     8.5  Artery,  Vein,  &  Capillary  Structure

HEART    Helps  pump  blood,  is  muscular,  and  around  the  size  of  your  fist.    Divided  into  four  chambers,  called  the  atria  and  ventricles    We’ll  learn  more  next  Nme!!!
