Functions of the Blood

Plasma is the liquid bit of the blood and carries nearly everything

• Red/White Blood Cells and platelets
• Digested food products
• Carbon Dioxide from the body cells to the Lungs
• Urea
• Homones, which act as chemical messengers
• Heat Energy

Red Blood Cells have the Job of carrying Oxygen

• Red Blood Cells are small and have a biconcave shape ehich gives a large surface area for absorbing and releasing oxygen.
• Contain Haemoglobin, called oxyhaemoglobin when it reacts with Oxygen.
• They don't have a Nueclus, so more space.
