  2. Objectives Biology is the study of living organisms. It seems that this subject is so big that there are a lot of facts for students to memorize. However, studying biology is not as difficult as many students think. To learn about the inside of the body and how different parts work is very exciting! Together with the recent development of information technology, students can become much more actively involve in the learning processes. Therefore, Power Point, Internet and other technology are used in this lecture to produce text, graphics, video and animation to try to make studying the types of blood vessels, the structure of the heart and the like easier and more enjoyable.

  3. 1/ Nowadays in Hong Kong, to avoid virus transmission, any experiment requiring the use of human blood cannot be performed in school laboratory. Therefore, compatibility of any two blood types cannot be tested in real time. This academic multimedia package allows this dangerous experiment : Human Blood Group Experiment, to be simulated in a classroom or in a laboratory, thus enhancing in-class activities and capturing student attention. 2/ The heart beat is demonstrated in the Heart Video so as to show the size of the real human beat and the ‘lub’ and ‘dup’ sounds clearly. 3/ Biological key words’ pronunciation are recorded. 4/ The content page allows teachers to focus on process, collaborative writing. Characteristics

  4. 5/ Parts called checkpoints are given in each section can help students grasp and remember the main ideas and concepts. Use these to emphasize what students need to learn and thus can be used to evaluate the teaching or learning processes. 6/ Independent learning is facilitated when students connect their personal computers to the Internet and using this package. This powerpoint can serve as self-review after lesson. 7/ Use the linked homepage to monitor education related listservs on the Internet. This keeps teachers and students in touch with the current trends. Provide a channel for students asking question independently and at home. 8/ Homework is given at the end of the unit.

  5. Analyze learners Class : F.4 science students (Total:40 students) Age : 15-16 Grade : Band 2 - 3 Altitude : Passive and silent, like creating approach, medium interest in Biology Previous knowledge : 1.The structure and composition of mammalian blood 2. The functions of blood

  6. User guide 1/ PC requires the QuickTime for Windows and the Sound Application. 2/ Run the program after putting the msvbvm50.zip file into ‘ \windows\system\ ‘ through the unzip program. 3/ It is recommended for students to work in the groups. 4/ At the beginning of each page is a key question, which relate the content of the next page. Teachers are recommended to ask students to answer these before going to the next part. 5/ This is a teaching aid. • 6/ Keys: • Press to go to the particular page (targeted page) • Press to have recording of pronunciation • Press to go back to the Content page • Press to go to the Human Blood Group Experiment • Press to have Human Heart Video

  7. H K C E E Level Biology

  8. Blood Circulation in Man

  9. Contents • Review • Composition of blood • Function of blood • Blood Transfusion • Human Blood Group • Blood Circulation • Blood vessels • Heart • Online Resources for Students Self-learning • Homework

  10. Whole Blood Red Blood Cell White Blood Cell 90 % Water Dissolved Substances Platelets Composition of Mammalian Blood Blood Cell (45% by volume) Plasma (55% by volume)

  11. Functions of Mammalian Blood • Transport • Defense against Infection • Regulation

  12. Blood Transfusion In emergencies an injured person may die... How can we save his life? Any criteria for Blood Transfusion?

  13. Y E S Do you know your blood group? A AB B O

  14. Human Blood Groups

  15. Human Blood Groups A B Agglutination Donor Recipient

  16. Have you ever donated blood in the Hong Kong Red Cross Blood Donation Center?

  17. Heart Vein Artery Venule Arteriole Capillary Blood Circulation

  18. Blood Vessels Artery Vein Are there any differences?

  19. Differences between Arteries & Veins 1/ Direction of blood flow 2/ Pulse 3/ Pressure 4/ Wall 5/ Valves 6/ Lumen 7/ Blood content

  20. Differences between Arteries & Veins Arteries Veins 1/ Direction of blood flow Away from Heart Return to Heart   2/ Pulse 3/ Pressure High Low

  21. Differences between Arteries & Veins Arteries Veins 4/ Wall Thick Thin

  22. Differences between Arteries & Veins Arteries Veins  5/ Valves  Except the pulmonary artery Prevent back-flow What’s the use of valve?

  23. Valve open blood can flow Valve closed blood can’t flow back Valves promote One-way Flow

  24. Blood squeezed towards heart Valves closed Prevent back-flow Muscle Contraction supports blood flow in Veins Muscle contracted

  25. Arteries Veins Deoxygenated Except the pulmonary vein Except the pulmonary artery Differences between Arteries & Veins 6/Lumen 7/Blood content Small Large Oxygenated

  26. Checkpoint State any three differences between Arteries and Veins.

  27. Nutrients Thin wall (one cell) O2 CO2 Waste Capillaries • Smallest blood vessels Diffusion

  28. Checkpoint Which have the greatest & lowest blood pressure, Artery, Vein or Capillary? Greatest :Artery Lowest :Vein

  29. H e a r t Blood Circulation in Man Introduction

  30. H e a r t To lung To body Pulmonary artery Aorta Pulmonary vein Atrium Bicuspid valve Vena cava Tricuspid valve Ventricle

  31. H e a r t Human Heart Video

  32. Online Resources for Students Self-learning 1/ You can ask question & get answer. Please feel free to visit this web site. http://www.school.net.hk/question/Biology/question1.html 2/ This is a self-learning homepage and the name is : The Heart: An Online Exploration http://sln.fi.edu/biosci/heart.html Some information about this site : Explore the heart. Discover the complexities of its development and structure. Follow the blood through the blood vessels. Wander through the web like body systems. Learn how to have a healthy heart and how to monitor your heart's health. Look back at the history of heart science. Go to Web Site : > Go to Web Site : >

  33. Homework 1. Can a person with blood group B donate his blood to a person with blood group A? Why? 2. Compare & explain the oxygen content of blood in arteries & veins in a living mammal. 3. Draw & label a mammalian heart.

  34. Good Bye Class
