Question 1

Question
Platelets are small fragments of cells. They help the blood to clot at a wound, preventing excessive bleeding and bruising.
Answer
  • True
  • False

Question 2

Question
Red blood cells carry oxygen from the lungs to all the cells in the body. They have a concave shape which means that they have a large surface area for absorbing oxygen.

In body tissues, the reverse happens - oxyhaemoglobin splits up into haemoglobin and oxygen.
