Hemoglobin is like the Uber driver for oxygen in your blood. It’s a protein that helps transport oxygen from your lungs to the rest of your body. When you breathe in, oxygen molecules attach to the hemoglobin in your blood, like passengers getting into an Uber car. The hemoglobin then carries these oxygen molecules to all the different parts of your body that need oxygen to function properly. Without hemoglobin, your body wouldn’t be able to get the oxygen it needs to keep you healthy and energized.
