2) "Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart."
3) A heart attack is a blockage of blood flow to the heart muscle.

Explanation:
"The Turtle" is a poem by author Mary Oliver. The speaker in the poem talks of the beauty and effortlessness of turtle laying eggs in the sand. It's a sacred action, which the turtle itself cannot understand since the drive to do it does not come consciously. It is a purely instinctive drive, guided by nature. The speaker admires the turtle's determination and patience in completing the task while remaining unaware of itself as an individual. The turtle sees itself as the world, and the world as itself.
