Paper 1
Revise: Skeletal functionsRed blood cells carry oxygen around the body. During an endurance run, they transport oxygen to working muscles, where it is needed for aerobic respiration to release energy. Blood cell production therefore helps support sustained physical activity.
A blood cell containing haemoglobin that transports oxygen around the body.
Blood cells are produced in bone marrow, not in the hard outer part of a bone. Red blood cells carry oxygen; white blood cells fight infection.
Link the adaptation to performance: more red blood cells → greater oxygen-carrying capacity → sustained aerobic exercise → a potentially faster time.

Revise: Cardiovascular System Structure and FunctionCapillaries are the smallest blood vessels. Their narrow passages allow red blood cells to squeeze through, and their walls are only one cell thick. This thin barrier allows substances such as oxygen and carbon dioxide to diffuse between blood and surrounding tissues.
