Gets oxygen to every cell in teh body and remove waste
products
Group of similar cells whihc work together to perform a specific function
Blood
Transports substances around the body
Cells are suspended in a liquid called plasma
Tranport oxygen around the body
Biconcave shape to give them a large surface area for absorbing
oxygen Adaptions
Contain haemoglobin which carries oxygen
No nucleus, so more room for haemoglobin
All body cells need oxygen for respiration - a process which Red blood cells
releases energy
Oxygen enters the lungs when you breathe in, then red blood
cells transport the oxygen from the lungs to all the cells in the
body
Lungs - oxygen diffuses into the blood, oxygen combines with Transporting oxygen
haemoglobin in red blood cells to become oxyhaemoglobin
In body tissues - oxyhaemoglobin spilts up into haemoglobin and Blood structure
oxygen to release oxygen to the cells
Help to defend against microorganisms that cause disease, part
of the immune system
Phagocytes - white blood cells that engulf and digest unwelcome
microorganisms - phaocytosis
White blood cells
Lymphocytes - produces antibodies
