Lesson Title: Today we are learning about
What are the components and functions of blood?
Remember to check for PROGRESS
Focus on Knowledge, Skills and Understanding
Success Criteria: You will show your learning by...
  1. Blood is a tissue consisting of plasma, in which the red blood cells, white blood cells and platelets are suspended.
  2. Students should know the functions of each of these blood components.
  3. (WS) Evaluate risks related to use of blood products.
  4. Students should be able to recognise different types of blood cells in a photograph or diagram, and explain how they are adapted to their functions.
  5. The body contains three different types of blood vessel: ? arteries ? veins ? capillaries.
  6. Students should be able to explain how the structure of these vessels relates to their functions.
  7. Students should be able to use simple compound measures such as rate and carry out rate calculations for blood flow.
Think about how you can match the needs of ALL students
Keywords:
  • Blood: Tissue that is liquid and has the role of transporting substances around the body. (1)
  • Capillary: Permeable blood vessel with a wall one cell thick where exchange between the blood and cells of the body takes place. (1)
  • Vein: Impermeable blood vessel that carries blood back to the heart. (1)
  • Artery: Impermeable blood vessel that carries blood from the heart. (1)

AFL/Key Questions:
  1. What different types of cells make up blood tissue?
    Blood is a tissue consisting of plasma, in which the red blood cells, white blood cells and platelets are suspended.
  2. What are the functions of the components of blood? Plasma, red blood cell, white blood cell, platelets.
    The functions of the components of blood are: Plasma: suspends the red and white blood cells Red blood cell: transports oxygen and carbon dioxide around the body White blood cell: attacks and kills pathogens Platelets: causes blood to clot
  3. What risks are related to the use of blood products?
    Some of the risks related to the use of blood products can include allergic reactions and blood borne infections.
  4. How are the red and white blood cells adapted for their functions?
    White blood cells are adapted to their function of killing pathogens as they produce antibodies, antitoxins and they can change their shape to squeeze into blood vessels. Red blood cells are adapted to their function of transporting oxygen and carbon dioxide as they have a large surface area, they dont have a nucleus and have a thin outer membrane for rapid diffusion.
  5. What are the three different types of blood vessel found in the body?
    The three types of blood vessels are arteries, veins and capillaries.
  6. How does the structure of arteries, veins and capillaries relate to their functions?
    The function of arteries is to carry blood away from the heart, they have narrow lumen and their walls are made of thick elastic fibers to withstand the high pressure blood flow. The function of veins is to carry blood back to the heart, they have wide lumen and thin walls to reduce resistance of blood flow. The function of capillaries is to support the exchange of substances to cells in the body. They have very narrow lumen as blood flow is not under high pressure and thin walls for rapid exchange of substances.
  7. How do you calculate the rate of blood flow?
    Rate of blood flow can be calculated using: rate = blood volume / time
