What is Plasma in our blood?

• A liquid that carries blood cells around our body

• A jelly like clot that forms around wounds to prevent bleeding

• Cells that carry Oxygen from the lungs to the cells that need it

• Cells for the body's defence system against harmful microorganisms

What are Platelets in our blood?

• A liquid that carries blood cells around our body

• A jelly like clot that forms around wounds to prevent bleeding

• Cells that carry Oxygen from the lungs to the cells that need it

• Cells for the body's defence system against harmful microorganisms

What are Red Blood Cells in our blood?

• A liquid that carries blood cells around our body

• A jelly like clot that forms around wounds to prevent bleeding

• Cells that carry Oxygen from the lungs to the cells that need it

• Cells for the body's defence system against harmful microorganisms

What are White Blood Cells in our blood?

• A liquid that carries blood cells around our body

• A jelly like clot that forms around wounds to prevent bleeding

• Cells that carry Oxygen from the lungs to the cells that need it

• Cells for the body's defence system against harmful microorganisms

What are Arteries?

• They carry oxygenated blood from your heart to your organs. They have a small lumen but thick walls and elastic fibres in order to stretch and withstand the high pressure of blood

• They carry de-oxygenated blood away from your Organs and back to your heart. They have a large lumen and thin walls. They have valves that prevent the backflow of blood

• They form a huge network of tiny vessels. They are narrow and small with very thin walls one cell thick to allow oxygen and glucose to defuse into the blood more easily

What are Veins?
