Of course blood involve in transportation of respiratory gases. So blood carry O2 to cells.
Hemoglobin helps blood function as the carrying molecule for oxygen. Hemoglobin is found in the red blood cells.
Red blood cells contain Hemoglobin which carry oxygen
Red blood cells
Hemoglobin is the oxygen carrying molecule in red blood cells.
Red blood cells are essential for carrying oxygen from the lungs to all parts of the body. Without enough red blood cells, our organs and tissues would not receive the oxygen they need to function properly, leading to serious health problems.
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.
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.
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.
Erethrocytes
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.
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.
then they are red if they are not carrying oxygen then they are a purple red.
