Human Circulatory System

Explain the function of red blood cells in the human circulatory system.

• Red blood cells regulate body temperature in the circulatory system.

• Red blood cells produce antibodies that destroy pathogens

• Red blood cells mainly carry carbon dioxide around the body

• Red blood cells mainly carry oxygen around the body

How is oxygen transported in the blood?

• Binding to haemoglobin in red blood cells

• Binding to haemoglobin in white blood cells

• Dissolving in plasma

• Transported by platelets

What is the role of plasma in the blood?

• Plasma is involved in the production of red blood cells

• Carries nutrients, hormones, and waste products

• Plasma is responsible for carrying oxygen to the body

• Plasma helps in muscle movement

Which of these following is the function of white blood cell?

• Transport oxygen

• Producing antibody

• Blood clotting

• Transport hormone

What protects the body against blood loss?

• Clots formed by clusters of leukocytes.
