Explain why having more red blood cells per cm3 of blood is an advantage to an athlete. (3 Marks)
Red Blood Cells (RBC’s) contain haemoglobin. Therefore, more RBC’s results in more haemoglobin present.Haemoglobin carries oxygen, therefore, more oxygen can be transported to cells such as muscle cells.More oxygen transported to cells results in more aerobic respiration of cells such as muscle cells.
