The oxygen-rich hemoglobin.
If you wanted to be really specific, oxygen makes blood red as the colour of blood underneath the skin is blue.
These cells' cytoplasm is rich in haemoglobin, an iron-containing biomolecule that can bind oxygen and is responsible for the blood's red color.
Each hemoglobin protein in blood is made up of subunits called hemes. It is these hemes that give blood its red colour.
Iron in hemoglobin protein.
The Answer Is Circulatory System That Makes Blood Cells RED ! it is the heme part of the haemoglobin that gives blood cells their bright red colour.
No red blood cells are formed in bone marrow
Red bone marrow produce RBCs (red blood cells), WBCs (white blood cells), and platelets.
The bone marrow is a spongy tissue that makes red blood cells. This process is called hematopoiesis.
Red and white cells
The iron in your blood
In the blood, their presence makes blood red.
Hemoglobin makes the red color.
oxygen makes blood red go read a science book
The protein hemoglobin, found in the red blood cells, is what makes blood red.
Red Blood...it's what makes your blood red.
The protein hemoglobin, found in the red blood cells, is what makes blood red.
oxygen is what makes your blood red... you may not know this but when your blood is not seen it is blue
Blood is red because oxygen makes contact with it.
Your Blood
oxygen is the answer
The Answer Is Circulatory System That Makes Blood Cells RED ! it is the heme part of the haemoglobin that gives blood cells their bright red colour.
