Question 20

Coronary artery

Answer 20

an artery that provides the heart with oxygen and glucose.

Question 21

Why are the muscle walls of the ventricles much thicker than the ones of the atria?

Answer 21

The atria pump blood down into the ventricles and the ventricles pump blood to the arteries. The ventricles require more effort so they have thicker muscle walls.

Question 22

Why are the muscle walls of the left ventricle thicker than the right one?

Answer 22

The left the ventricle has to pump blood to the whole body whereas the right ventricle has to pump to only one organ; the lungs.
