Detailed explanation-1: -Red blood cells are responsible for transporting oxygen from your lungs to your body’s tissues. Your tissues produce energy with the oxygen and release a waste, identified as carbon dioxide. Your red blood cells take the carbon dioxide waste to your lungs for you to exhale.
Detailed explanation-2: -Red blood cells are adapted for the transport of oxygen. They are small and flexible so they can fit through narrow vessels, have a bi-concave shape which maximises their surface area to absorb oxygen, have a thin membrane so gases easily diffuse through, and contain haemoglobin which binds to oxygen.
Detailed explanation-3: -In blood, oxygen and carbon dioxide are carried by RBC and blood plasma. 97% of oxygen is transported by RBC and the rest of the 3% is by the plasma. In the RBC, hemoglobin (respiratory pigment) is found that binds the oxygen and form oxyhemoglobin. 70% of the carbon dioxide is carried by RBC.
Detailed explanation-4: -The main role of red blood cells is to carry oxygen around your body and to transport carbon dioxide to the lungs, from where it can be exhaled. A healthy diet containing essential minerals and vitamins will help your body produce enough red blood cells.
