Blood
• Functions of blood– Carries oxygen and nutrients to all your
tissues– Removes wastes such as carbon dioxide and
urea– Transports hormones– Helps to regulate the body’s temperature and
water content

The parts of blood
• Red blood cells– Contain the red pigment
haemoglobin that carries oxygen.
– Biconcave shape increases surface area so gas exchange is more efficient.
– No nucleus so more room for haemoglobin
• Plasma– A pale yellow watery fluid
containing nutrients, hormones and proteins

The parts of blood
• White blood cells– Various shapes– Have a nucleus– Defend against infection– More wbc in blood when you have an infection.
• Platelets– Small fragments of cells involved in blood clotting.– Clotting is important in stopping the flow of blood after an
injury.

Problems with blood
• Sickle – cell anaemia• Some of the red blood
cells are shaped like sickles, meaning they don’t carry oxygen as efficiently

Problems with blood
• Trypanosomes– Parasites– Single-celled
organisms that live some of their life cycle in the blood of animals, including humans.
– Cause sleeping sickness a common disease in Africa
