Hemoglobin

Hemoglobin is an iron-containing protein found in red blood cells that is responsible for delivering oxygen to the body’s organs and tissues. It binds to oxygen molecules in the lungs and carries them as it circulates throughout the body. When hemoglobin is low, the body’s tissues don’t get enough oxygen and a person can feel weak and tired. One way to measure hemoglobin is through a blood test, which can be used to detect anemia or other illnesses. Hemoglobin is important for maintaining good health, and proper levels can be achieved by eating a balanced diet and exercising regularly.
