Question

1. what is atherosclerosis?

a method used to correct arrhythmias
another word for high blood pressure
the build up of fats and cholesterol in the walls of blood vessels
the field in which scientists investigate how many people have a disease

Explanation:

Atherosclerosis is a medical condition. It is characterized by the accumulation of fats (such as cholesterol) in the walls of blood vessels. This build - up can narrow the blood vessels and affect blood flow.

• Option 1: A method to correct arrhythmias is not related to the definition of atherosclerosis. Arrhythmia correction methods are things like cardioversion (electrical or chemical), while atherosclerosis is about vascular changes.
• Option 2: High blood pressure (hypertension) is a different condition from atherosclerosis. High blood pressure is related to the force of blood on the vessel walls, not the build - up of fats.
• Option 4: The field where scientists investigate how many people have a disease is epidemiology, not the definition of atherosclerosis.

Answer:

the build up of fats and cholesterol in the walls of blood vessels
