• All of the colors are absorbed except for blue,
which is reflected
Another Reason..
• Many people may have seen a graph at
the doctor and it could have shown
arteries and blood. The color for blood
would be blue. Some people thought
they used the actual colors. So, they
thought blood was blue.
Cyanosis
• It is a physical condition
– Where your skin looks blue and so does your
blood
• This happens because there is not enough
oxygen
– Cyanosis results in many problems
• Heart failure
• Lung disease
• Respiratory distress syndrome

Cyanosis
• The Path
– “Hemoglobin is in the red blood cells
• It picks up oxygen from the lungs
– It goes through the arteries and releases it to
a cells though tiny capillaries.
– The blood circulates back to the lungs through
capillaries and veins.”
Health A to Z
Vocabulary
• Hemoglobin- red blood cells that transfer
oxygen and contain iron
• Plasma- is the liquid part of blood
• Deoxygenated blood- blood without oxygen
• Venous blood-is blood returning to the heart,
comes from the veins
• Arterial blood-Comes from the arteries
Vocabulary
• Cyanosis- when your skin or nails are a

The Survey
• With the survey, I had to ask 20 people my
question “What color is blood in your veins?.”
• The people I interviewed either didn’t know or
were correct on their guess
– No one answered with an “I know for a fact…”,
everyone said their answer as a question. Blue? Or
Red?
• Everyone had a good explanation on why they
thought their blood was red or blue.
