1.	What is difference between lungs and heart?
Answer» heart is a muscle that depends on oxygen being delivered to it via the lungs in order to even function. No oxygen and the heart stops beating.Conversely, the lungs can only oxygenate the blood if the heart pumps blood through them. As you can tell, both are important for survival. Not only do both organ systems help one another in their overlapping functions, but so, too, do they sometimes end up hurting one another if one of them gets sick.
