Kahoot!
Double Circulation system
Red Blood cells
Oxygenated blood travels from the heart to the body
Deoxygenated blood travels from the body to the heart
Blood Cells
These are specialised cells designed to carry oxygen.
They have a shape which gives them a large surface area.
They contain a special substance called haemoglobin
They have no nucleus to give them more space to carry oxygen.

Blood is made of four parts:
Red blood cells
White blood cells
Platelets
Plasma
Blood picks up oxygen from the lungs and drops off carbon dioxide
Arteries carry blood away from the heart
Veins carry blood back to the heart
Capillaries are very small blood vessels that deliver blood to every cell
Blood cells are made inside your bones in an area called bone marrow

I can explain what a double circulation system is (Level 6)
Heart Rate
The heart
Oxygenated blood travels from the heart to the body
Deoxygenated blood travels from the body to the heart
F
D
Work in pairs or threes with people on your table
Measure your heart rate (how many beats in one minute)
Jump on the spot for one minute
Measure your heart rate again
Has it changed, why?
What do you notice about your breathing?
Write a couple of sentences in your book about why these differences happen.
E
Body cells use oxygen and give blood CARBON DIOXIDE
Blood travels from the heart to the lungs
Heart
The heart pumps blood around your body.
Blood goes through the heart twice on each journey round the body.
