Which of the following is NOT a disorder of the cardiovascular system?

Asthma is classified as a respiratory disorder, primarily affecting the airways and the lungs. It involves chronic inflammation of the air passages and leads to symptoms like wheezing, shortness of breath, and coughing. In contrast, heart attack, hypotension, and stroke are all conditions directly related to the cardiovascular system. Heart attacks involve the blockage of blood flow to the heart muscle, hypotension is a condition characterized by abnormally low blood pressure affecting circulation, and strokes (CVA) are caused by interruptions in the blood supply to the brain, resulting in neurological deficits. Understanding the distinctions between these health conditions is crucial for recognizing the various systems in the body they affect.
