Answer to Question 1

A
Hemoglobin transports most oxygen and serves as a carrier for both oxygen and carbon dioxide. White blood cell count is a lab test to measure infection. Electrolytes do not indicate oxygen levels but do indicate electrolytes like sodium and potassium. Creatinine levels measure kidney function.

Answer to Question 2

D
The heart supports perfusion, the movement of blood into and out of the lungs to the organs and tissues of the body. The primary functions of the lungs include ventilation, the movement of air in and out of the lungs, and diffusion, the movement of gases between air spaces and the bloodstream. Respiration is the exchange of oxygen and carbon dioxide during cellular metabolism.
