Exploring Factors Influencing Blood Flow

What is the primary function of arteries?

• Carry oxygenated blood to the heart

• Carry blood away from the heart

• Carry deoxygenated blood away from the heart

• Supply blood to the heart itself

What is the main difference between arteries and veins?

• Arteries carry oxygenated blood, veins carry deoxygenated blood

• Arteries and veins both carry deoxygenated blood

• Veins carry oxygenated blood, arteries carry deoxygenated blood

• Arteries and veins both carry oxygenated blood

How does blood pressure affect heart health?

• Higher blood pressure can lead to heart diseases

• Lower blood pressure indicates better physical fitness

• Blood pressure has no impact on heart health

• Higher blood pressure reduces heart disease risk

How does the heart receive oxygenated blood?

• Via the aorta

• Through the pulmonary veins

• Via the vena cava

• Through the pulmonary artery

What role does exercise play in maintaining heart health?

• Increases the risk of atherosclerosis

• Reduces the chance of heart disease

• Has no effect on heart health

• Decreases blood flow to muscles

What causes atherosclerosis?

• Plaque buildup in arteries

• High oxygen levels in blood

• Lack of exercise

• Low blood pressure

What is a common symptom of atherosclerosis?

• Chest pain

• Frequent headaches

• Increased heart rate

• Sudden weight gain

What is the effect of atherosclerosis on arteries?

• Leads to stiffening due to plaque buildup

• Causes them to widen

• Increases their oxygen-carrying capacity

• Makes them more flexible

What can cause a stroke?

• Blocked artery or leaking blood vessel

• Excessive exercise

• High oxygen levels in the brain

• Decreased blood pressure

What is the primary cause of high blood pressure?
