What describes the relationship between respiration and the rest of the body?

• A. Respiratory Problems Can Deprive Other Body Systems Of Oxygen, Causing Failure
• B. Respiratory Problems Only Affect The Lungs
• C. Respiratory System Is Independent Of Other Systems
• D. The Respiratory System Produces Waste

Answer: (A)

Breathing supplies oxygen to all tissues and removes carbon dioxide, which is essential because cells use oxygen to produce energy. When respiration is impaired, tissues can be starved of oxygen (hypoxia). Without enough oxygen, the function of other organs—like the brain, heart, and muscles—deteriorates quickly and can fail if not corrected. That’s why the correct choice describes how respiratory problems can deprive other body systems of oxygen and lead to failure. It isn’t accurate to say it only affects the lungs, or that the system is independent, and while CO2 is a waste to be exhaled, the main role is supplying oxygen and removing CO2, not simply “producing” waste.
