Red blood cells carry oxygen using haemoglobin. Without enough of them, tissues receive less oxygen and fatigue appears. Their disc shape helps them squeeze through capillaries and maximise space for haemoglobin.

Iron is needed to build haemoglobin. White cells fight infection; platelets help clotting — different jobs from oxygen transport.

Biology lessons in Gulberg can separate “blood” into clear cell roles instead of one vague idea of “healthy blood.”
