Red blood cells have a protein known as hemoglobin that is rich in iron making it good candidate to transport oxygen from the lungs to the body.
Red blood cells
Hemoglobin is the oxygen carrying molecule in red blood cells.
Red blood cells contain a protein called hemoglobin. Hemoglobin is able to bind to oxygen molecules. Therefore, the presence of hemoglobin the red blood cells makes them capable of carrying oxygen.
Hemoglobin is the oxygen-carrying component in red blood cells. Hemoglobin is a protein that has an iron molecule. Aside from red blood cells, there are white blood cells, which also are important components of the blood.
Erethrocytes
Red blood cells, also known as erythrocytes, are responsible for carrying oxygen to cells throughout the body. They contain hemoglobin, a protein that binds to oxygen in the lungs and releases it to tissues in need of oxygen.
Red blood cells are responsible for carrying oxygen to the blood vessels spanning the whole body and eventually to the organs. Therefore, they are called the blood's work force.
Red blood cells, specifically the protein hemoglobin within red blood cells, is responsible for carrying oxygen in the blood. Hemoglobin binds to oxygen in the lungs and transports it to tissues throughout the body.
then they are red if they are not carrying oxygen then they are a purple red.
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.
Its called hemoglobin. it also gives the color to red blood cells, when carrying oxygen, and the bluish color when they carry carbon dioxide.
