Components of the blood
Mix and Match
Red blood cells (RBC)
Plasma
White blood cells
Platlets
Part of the body’s immune system and
is used to fight of pathogens (germs)
Carries a range of substances,
including: Carbon dioxide, hormones,
glucose, urea and more.
Used to block damaged blood vessels
and prevent blood loss.
Carries oxygen from the lungs to
different tissues in the body. Contains
a substance called hemoglobin.
Transfer of oxygen
In capillaries, oxygen gradually leaves the red blood cells
and dissolves into the plasma. This leaks out through the
minute holes in the capillaries and forms tissue fluid, which
then caries oxygen to the cells. Plasma has glucose ad
other nutrients dissolved in it and so these are also in the
tissue fluid.

of smoking. Include all the information in the
success criteria.
Stretching Activity
• Compare emphysema to
bronchitis.
• Present your board to your
parents and get written
feedback.
In groups of two or three, carry out the exercise and
breathing experiment using the learning sheets shown
below. You have twenty minutes to create a prediction
and collect results.
If you complete all
your work, attempt
to do the second
page on the exercise
and breathing
learning sheet.
Conclusion
1) As the intensity of the exercise increased, the amount
of oxygen required also increased. This caused an
increase in the student’s breathing rate.
2) As the intensity of the exercise increased, the amount
of oxygen required stayed constant and the breathing
rate stayed constant too.
