The Red Blood Cells because they are the most dominant cells in the blood

Answer 4

Yes you are right if you said hemoglobin
but your wrong if you said blood is blueish or blue before it is exposed to oxygen. Blood is always always red the reason it looks blue is that the combination of looking at it through our skin and the dark red from de-oxygenation coupled with poor light relfection makes the blood look blue.

The protein hemoglobin is responsible for the red color.
When the hemoglobin comes in contact with oxygen to become oxyhemoglobin, the blood becomes bright red. When the oxygen is released it becomes deoxyhemoglobin and may "appear" bluish when viewed through blood vessel walls.

Answer 7

Haemoglobin and Red blood cells

Answer 8
