Question

How would a dislodged piece of plaque in the cardiovascular system most likely affect an otherwise healthy person?

The right pulmonary artery could become blocked, restricting blood flow to the right lung.

A narrow region of the superior vena cava could become blocked, restricting blood flow to the heart.

A smaller artery in a leg could become blocked, restricting blood flow to capillaries in the leg.

A narrow vein in the brain could become blocked, restricting blood flow to capillaries in the brain.

I really dont know which one it could be please helppp!!

Answer 1

Many otherwise healthy people have heart attacks when a piece of plaque becomes dislodged and blocks the blood flow to the heart, suggesting that the answer would be B. However, healthy people can also experience strokes, caused from restricted blood flow to the brain, so it could be either of these answers.
Lung and leg seem less probable, don't you think? You don't hear much about healthy people randomly having blockages of the blood flow to their lungs and legs, although you do hear a lot about heart attack and strokes.
Which one do you think it could be?

Answer 2

i was either going with the heart or the brain one but its hard because all of them could possibly happen

Answer 3

Yeah I totally hear you. They are all possible but you're right to narrow it down to heart or brain since the question asks for the most likely result.
I would go with the heart one if I were you, because the question talks about plaque in the cardiovascular system. A stroke would occur because of plaque blocking the arteries in the brain, not the cardiovascular system.

Answer 4

okay thank you so much!

Answer 5

No problem! :)

Answer 6

"A stroke would occur because of plaque blocking the arteries in the brain, not the cardiovascular system."

all arteries, veins, capillary are part of the cardiovascular system

Answer 7

Yeah that's fair. However, I still think that the answer they're looking for is the heart. Am I wrong?
