Which category does hypertension fall under?

Hypertension is categorized as a cardiovascular disease because it primarily involves the heart and blood vessels. It is characterized by consistently elevated blood pressure, which can lead to various cardiovascular complications such as heart disease, heart attacks, and strokes. The condition affects the overall cardiovascular system's function, as high blood pressure can damage arteries, making it more difficult for the heart to pump blood effectively.

In contrast, the other categories listed do not pertain to hypertension. Respiratory diseases involve conditions affecting the lungs and breathing, musculoskeletal diseases concern the muscles, bones, and joints, and neurological diseases deal with disorders of the nervous system. Since hypertension directly impacts the cardiovascular system, it clearly falls under the umbrella of cardiovascular diseases.
