Peripheral artery disease primarily affects which part of the body?

Head and neck
Arms
Calves
Fingers

The correct answer is: Calves

Peripheral artery disease (PAD) primarily affects the arteries that supply blood to the legs, particularly the calves. This condition occurs when there is a narrowing or blockage of the peripheral arteries, often due to atherosclerosis, which reduces blood flow to the limbs. Individuals with PAD may experience symptoms like pain, cramping, or weakness in the calves, especially during activities such as walking or climbing stairs. The condition is a manifestation of systemic vascular disease and is closely associated with other cardiovascular problems. While PAD can impact various areas of the body, it is most commonly associated with the lower extremities, particularly the calves, as they are further away from the heart. This decreased blood flow can lead to more severe complications if left unaddressed, including difficulty in walking and potential ulcers or wounds that heal poorly due to insufficient circulation.
