True or False: Blood with a hemoglobin level of 15g can transport approximately 20mL of oxyhemoglobin.

The assertion that blood with a hemoglobin level of 15g can transport approximately 20mL of oxyhemoglobin is true. Hemoglobin is a protein in red blood cells responsible for carrying oxygen from the lungs to tissues throughout the body. It has a specific capacity for oxygen binding: one gram of hemoglobin can carry about 1.34 mL of oxygen when fully saturated.

Given a hemoglobin concentration of 15 grams per deciliter, the potential total oxygen transport capacity can be calculated. Multiply the hemoglobin level (15 grams) by the amount of oxygen carried per gram (1.34 mL/g), yielding approximately 20.1 mL of oxygen at full saturation. This calculation confirms the capacity for approximately 20 mL of oxyhemoglobin under normal physiological conditions, validating the statement as accurate.
