Answer:
Lung disease is any problem in the lungs that prevents the lungs from working properly. There are three main types of lung disease:
Airway diseases -- These diseases affect the tubes (airways) that carry oxygen and other gases into and out of the lungs. They usually cause a narrowing or blockage of the airways. Airway diseases include asthma, COPD and bronchiectasis. People with airway diseases often say they feel as if they're "trying to breathe out through a straw."
Lung tissue diseases -- These diseases affect the structure of the lung tissue. Scarring or inflammation of the tissue makes the lungs unable to expand fully (restrictive lung disease). This makes it hard for the lungs to take in oxygen and release carbon dioxide. People with this type of lung disorder often say they feel as if they are "wearing a too-tight sweater or vest." As a result, they can't breathe deeply. Pulmonary fibrosis and sarcoidosis are examples of lung tissue disease.
Lung circulation diseases -- These diseases affect the blood vessels in the lungs. They are caused by clotting, scarring, or inflammation of the blood vessels. They affect the ability of the lungs to take up oxygen and release carbon dioxide. These diseases may also affect heart function. An example of a lung circulation disease is pulmonary hypertension. People with these conditions often feel very short of breath when they exert themselves.

Put it your own words cause this is kinda advance for 7th
Acidic groundwater dissolving limestone
Under the dissecting microscope I was able to view the surfaces of specimens such as a feather, insect, and leaf.
Under the compound microscope I was able to view a leaf, blood, and algae. I was able to observe the surface of the specimens in greater detail then I was able to view the surfaces under the dissecting microscope. For an example under the compound light microscope I was able to view the leaves surface which contained multiple lines that intertwined into each other and rectangular chambers of green dots. But under the dissecting microscope I was only able to view the surface of the leaf which consisted of thin white cracks in the leaf.
Under the scanning electron I was able to view the internal structure of the following specimens: a leaf, blood, and algae.
Under the transmission electron I was able to view a more in depth internal structure of the following specimens:a leaf, blood, and algae. I was able to observe the intern
al structures of the specimens in greater detail then I was able to view the internal structures under the scanning microscope. For an example under the TEM I was able to study the internal structure of a leaf which consisted of long thick and thin black and gray lines coated with black rectangles and tiny dots littering he perimeter of what looks to be the internal structure of the leaf. But with the SEM I was only able to view the first layer of the leaf's internal structure which consisted of mushroom like figures surrounded be compound and single molecules.
