@gethelpwithproctoredexam: The lungs are a pair of spongy, air-filled organs in the chest that are essential for breathing. Their main function is to exchange gases between the air and the blood. When we inhale, oxygen enters the lungs and passes into the bloodstream. When we exhale, carbon dioxide, a waste gas, is removed from the body. The lungs work closely with the heart and diaphragm to supply oxygen needed for energy, growth, and overall body function. #creatorsearchinsights #medstudent #nurselife #student #study
