3. What is in blood?
Red blood cells, white blood cells platelets and plasma – what do these do?
RBC – O2
Plasma –CO2, soluble food, waste material(urea)
Platelets – clots blood at area of cut
WBC antibody production and phagocytosis

4. Red blood cells
Contain haemoglobin – protein containing iron that picks up O2 when RBC pass through lungs
Adaptations – no, nucleus, haemoglobin- high affinity for O2
Becomes oxyhaemoglobin
Oxygen + haemoglobin oxyhaemoglobin
Oxygen is released at cells for respiration
Oxyhaemoglobin Oxygen + haemoglobin

5. Transport of urea Toxic chemical formed from the breakdown of proteins
Made in liver and excreted through kidneys
Transported in plasma

6. Transport of food
Glucose, amino acids and other water soluble substances transported in plasma
What cannot be transported in plasma?
Fats-transported in lymphatic system
