Research of Blood Circulation

-In blood there are Red Blood Cells, White Blood Cells and Platelets. 5 million of Red Blood Cells, 5,000 - 10,000 of White Blood Cells and 200,000 - 400,000 of Platelets.



-Red Blood Cells bring Oxygen which Lungs produce from Lungs to organs and cells such as Brain, Muscle, Eyes, Stomach, Large Bowel, Small Bowel, Liver, Kidney, etc.

-Each cells produce Carbon Dioxide. Then Red Blood Cells bring them back to Lungs and Lungs change CO2 to O2 and repeat.



-White Blood Cells kill germs in blood.

-When skin is injured, Platelets make a scab on the skin and it protects skin from germs.

-Red Blood Cell can changes its shape.

-Haemoglobin in Red Blood Cell makes the colour of the cell Red.

-Anemic person's skin looks bluish white because the number of Haemoglobin, which is Red, is less.
