4.4 Haemopoesis and disorders of blood components

What is haemopoiesis?

• The process of blood cell formation
• The process of blood cell destruction
• The process of blood cell transportation
• The process of blood cell regulation

What are the three types of blood cells produced during haemopoiesis?

• Red blood cells, white blood cells, plasma
• Red blood cells, white blood cells, platelets
• White blood cells, platelets, fats
• Red blood cells, plasma proteins, fats
• Red blood cells, platelets, plasma proteins

What is the main function of white blood cells produced during haemopoiesis?
