Detailed explanation-1: -A type of blood cell that is made in the bone marrow and found in the blood. Red blood cells contain a protein called hemoglobin, which carries oxygen from the lungs to all parts of the body.

Detailed explanation-2: -Red blood cells: Red blood cells (RBCs, also called erythrocytes; pronounced: ih-RITH-ruh-sytes) are shaped like slightly indented, flattened disks. 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.

Detailed explanation-3: -Hemoglobin is an oxygen-carrying protein found in red blood cells. It contains iron, and it gives the blood its red color. Q: What does hemoglobin do? Hemoglobin is vital to the body because it can bind to oxygen, carbon dioxide, and other groups such as sulfide and nitrogen oxide.

Detailed explanation-4: -Hemoglobin is the protein that carries oxygen and exists within each red blood cell.

Detailed explanation-5: -Red blood cells, or erythrocytes, are one of the components of blood. (The others are plasma, platelets and white blood cells.) They are continuously produced in our bone marrow.
