What are 3 components of blood?
white blood cells, red blood cells and platelets
8 of 12
Red blood cells
contains haemoglobin which binds to oxygen to transport from lungs to cells and tissues. no nucleus so more room for haemoglobin. very small and large surface area for quick diffusion.
9 of 12
White blood cells
protect body from infections. can change shape so can get out of blood vessels into tissues
10 of 12
Platelets
collect at wounds and trigger blood clotting (scabs)
