What is the primary function of coronary arteries?

• To supply oxygen-rich blood to the heart muscle

• To regulate heart rate

• To pump blood throughout the body

• To remove waste products from the heart

What process leads to the hardening of blood vessels?

• Embolization

• Thrombosis

• Atherosclerosis

• Angina

What happens to the heart muscle during stable angina?

• It receives too much oxygen

• It becomes hypoxic due to reduced blood flow

• It stops beating

• It becomes inflamed

What is a characteristic of stable angina?

• It occurs only during sleep

• Chest pain is relieved by rest

• Chest pain occurs unpredictably

• It is a type of heart attack

What is the main difference between stable and unstable angina?

• Stable angina occurs at rest, unstable does not

• Unstable angina is a heart attack, stable is not

What can cause a plaque to rupture in the arteries?

• Hypertension or spontaneous rupture

• Excessive exercise

• High cholesterol diet

• Low blood pressure

What is the term for a blood clot that completely blocks a blood vessel?

• Embolization

• Angina

• Atherosclerosis

• Thrombosis

What happens during a heart attack?

• The heart muscle receives too much oxygen

• A part of the heart muscle dies due to lack of oxygen

• The heart stops beating entirely

• The heart muscle becomes inflamed

How is heart failure different from a heart attack?

• Heart failure is when a part of the heart muscle dies

• Heart failure occurs only during physical exertion

• Heart failure is when the heart can't pump enough blood
