Answer 1

it cannot pump out enough of the blood it gets from the lungs.

Step-by-step explanation:

If the heart is ill or damaged, it cannot pump out enough of the blood it gets from the lungs. When that happens, pressure in the heart builds up and pushes fluid into the lungs' air sacs, where it doesn't belong. Breathing problems may happen over time, or they may come all of a sudden.
