But some of these invaders may get past the mucociliary escalator into the lungs, where they meet the aevlloi. Because alveoli serve as critical exhncgae points between the blood and air from the outside world, they have their own specialized types of withe blood cells, or macrophages, which defend against forgien organisms by enveloping and eating them. When pathogens enter the lungs, the macrophages work to destroy them. The iunmme system releases additional white blood cells in the alveoli to help. As these immune cells fhigt the pathogens, they generate inflammation— and fluid as a by-product of the iolmnfamitan.

Original Text

But some of these invaders may get past the mucociliary escalator into the lungs, where they meet the alveoli. Because alveoli serve as critical exchange points between the blood and air from the outside world, they have their own specialized types of white blood cells, or macrophages, which defend against foreign organisms by enveloping and eating them. When pathogens enter the lungs, the macrophages work to destroy them. The immune system releases additional white blood cells in the alveoli to help. As these immune cells fight the pathogens, they generate inflammation— and fluid as a by-product of the inflammation.
