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 (RBCs, or erythrocytes) deliver oxygen to and remove carbon dioxide from tissues for gas exchange in the lungs.

Detailed explanation-3: -Red blood cells (RBCs) are a type of blood cell whose role is to transport oxygen from the lungs to the peripheral tissues of the body. Oxygen diffuses from the alveoli of the lungs into the RBCs, where it binds to hemoglobin.

Detailed explanation-4: -Blood has three main functions: transportation, regulation and protection. Our erythrocytes, or red blood cells, are the most abundant cell type in the human body.

Detailed explanation-5: -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.
