Questions & Step-by-Step Solutions

What is the primary role of hemoglobin in the blood?
  • Step 1: Understand that hemoglobin is a protein found in red blood cells.
  • Step 2: Know that hemoglobin's main job is to carry oxygen from the lungs.
  • Step 3: Realize that when we breathe in, oxygen enters the lungs.
  • Step 4: Hemoglobin picks up this oxygen in the lungs.
  • Step 5: Hemoglobin then travels through the bloodstream to deliver oxygen to the body's tissues.
  • Step 6: After delivering oxygen, hemoglobin picks up carbon dioxide (a waste product) from the tissues.
  • Step 7: Finally, hemoglobin carries carbon dioxide back to the lungs to be exhaled.
