Blood in 60 Seconds! ⏱️ Everything you need to ace this topic for your GCSE Biology exam! 🩸🧬 🔬 Blood is made up of specialised cells like red and white blood cells, suspended in plasma. 💧 Plasma transports water and nutrients to tissues and removes waste like urea. 🛡️ Red blood cells contain haemoglobin that binds to oxygen and transports it around the body. 🦠 White blood cells fight infections by engulfing pathogens or producing antibodies. 🩹 Platelets aren’t true cells – they’re cell fragments that start the clotting process to form scabs.
