Hemoglobin.
Hemoglobin is the part of a red blood cell that gives it the red color and carries oxygen. Hemoglobin is a protein that binds to oxygen in the lungs and releases it to tissues throughout the body.
Hemoglobin carries the oxygen in the blood and it gives the red blood cells their color.
Hemoglobin
It gives up oxygen, and carries out carbon dioxide.
It gives up oxygen, and carries out carbon dioxide.
Blood is not always red. The colour is dependant on it's exposure to oxygen. If there is oxygen in the blood it has a red colour. That is why whenever you bleed your blood is red, because it reacts with the oxygen in the air. When there is no oxygen in your blood though, your blood has a blue colour.
The pigment present in red blood cells is hemoglobin. Hemoglobin is a protein that binds to oxygen in the lungs and carries it to the tissues throughout the body. It gives blood its red color.
Erythrocytes, or red blood cells, get their color from the iron-containing protein hemoglobin. Hemoglobin binds to oxygen in the lungs and carries it to tissues throughout the body. This oxygen transport allows erythrocytes to deliver oxygen to cells and remove carbon dioxide.
Blood will appear bright red when it has high oxygen content. This is because oxygen binds to hemoglobin in red blood cells, forming oxyhemoglobin, which gives the blood its bright red color.
The hemoglobin gives the cells its reddish hue and carries oxygen in the cell.
