Detailed explanation-1: -Red blood cells get their bright red color from a protein that allows them to carry oxygen from your lungs and deliver it to other tissues in your body (hemoglobin).
Detailed explanation-2: -RBCs contain hemoglobin (pronounced: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.
Detailed explanation-3: -The level or amount of oxygen in the blood determines the hue of red. As blood leaves the heart and is oxygen-rich, it is bright red. When the blood returns to the heart, it has less oxygen. It is still red but will be darker.
Detailed explanation-4: -When the red blood cells reach tissues that need oxygen, the oxygen is released from the haemoglobin and diffuses into the cells where it is used to make energy. All the systems in our body rely on oxygen to make energy.
