Answer:

1) A cardiovascular system is an organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes.

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.

Orr was crazy and could be grounded (blah blah)"(Joseph Heller 46).

,"There was only one catch, and that was Catch-22,...Orr was crazy and could be grounded (blah blah)"(Joseph Heller 46).
