If your heart is not strong enough or efficient enough, it is difficult to?

a. stretch.
b. lift weights.
c. breathe.
d. perspire.

The correct answer is C. Breath

Explanation:

Lungs and heart are responsible for the proper breathing and both are situated in the thoracic cavity. A proper function of the lungs requires the proper function of the heart and proper functioning of the heart requires the proper functioning of the lungs.

Therefore if the heart is not strong enough then it will be difficult to breathe because the heart pumps the oxygenated blood to the tissues and deoxygenated blood is pumped to the lungs so that the CO₂ can be exhaled. This is the reason that in heart failure people feel breath shortage.

Therefore the right answer is C. Breath.

my hamster died and my second hamster i got after that one died as well. i also lost two birds named rainbow and kiwi, (they didn't die, they flew off and escaped). i lost a cat named omi, and a dog named snoopie. the best way i got over it is, paying my respects, and just thinking that they were in a happy place. as well as just remembering but not thinking about it all the time, just do fun activities and try not to think about it too much. hope you feel better. i'm sorry about your loss. : (
