A. Within the normal range.

Explanation:

Hemoglobin is a protein molecule found in the red blood cells. It's primary function is to carry oxygen from the lungs to the tissues and carry carbon dioxide out of the tissues.

For men, the normal range for hemoglobin in the blood is between 14 g/100ml and 18 g/100ml. A low hemoglobin count could be an indication of anemia, while a high count could be attributed to lifestyle choices.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
