then they are red if they are not carrying oxygen then they are a purple red.
Red blood cells contain a protein called hemoglobin, which is responsible for carrying oxygen from the lungs to the rest of the body. Hemoglobin binds to oxygen in the lungs, giving red blood cells their red color.
Red blood cells, or erythrocytes, are primarily responsible for carrying oxygen from the lungs to the rest of the body tissues and removing carbon dioxide for excretion. They contain hemoglobin, a protein that binds to oxygen and gives blood its characteristic red color. Red blood cells are produced in the bone marrow and have a lifespan of about 120 days.
Red blood cells, also known as red corpuscles, are the most common type of blood cell. They are responsible for carrying oxygen from the lungs to all the tissues in the body, and for carrying carbon dioxide back to the lungs to be exhaled. Red blood cells contain a protein called hemoglobin, which gives them their red color and allows them to transport oxygen.
The red blood cells themselves do not take any action to get more oxygen, but the kidneys sense a lack of oxygen and produce more erythropoietin (hormone responsible for producing red blood cells) and this in turn increases oxygen levels
Hemoglobin is the iron oxygen carrying protein which gives blood its red color
the answer is that i dont know
Blood cells that are carrying oxygen will appear bright red, while blood cells that are not carrying oxygen will appear darker in color (usually dark red or purplish). This change in color is due to the presence or absence of oxygen-binding molecules like hemoglobin within the red blood cells.
Blood changes color at the lungs because it unloads carbon dioxide and absorbs oxygen. Red blood cells that are carrying oxygen are a brighter red color than red blood cells that are depleted of oxygen.
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen from the lungs to the body's tissues and organs. Their main function is to transport oxygen bound to hemoglobin, a protein that gives blood its red color.
Its called hemoglobin. it also gives the color to red blood cells, when carrying oxygen, and the bluish color when they carry carbon dioxide.
Red blood cells contain a protein called hemoglobin, which is responsible for carrying oxygen from the lungs to the rest of the body. Hemoglobin binds to oxygen in the lungs, giving red blood cells their red color.
Hemoglobin: the oxygen-carrying pigment of red blood cells that gives them their red color and serves to convey oxygen to the tissues
The color of a red blood cell changes depending on whether its hemoglobin is carrying oxygen. Oxygenated red blood cells are brighter in color.

Capillaries change color as they pass by body cells as the blood they contain loses oxygen. Oxygen-rich blood has a brighter color than oxygen-poor blood.
Human blood has red color when oxygenated which is mainly because of red blood cells. Its color changes to purple when present in oxygen deprived circumstances. To restore the color the blood has to be placed in oxygen rich environment.
