Answer:
1. Both are respiratory organs found in vertebrates.
2. Both enable the inhalation of oxygen and exhalation of carbon dioxide in the bodies of their host.
3. Respiratory membranes present in both make the exchange of gases easier.
4. Blood vessels found around them enable the breathing process.
Explanation:
Gills are respiratory organs which can be found in animals that live in water. These include fishes, amphibians like frogs, anthropods like insects, and annelids like worms. Gills are surrounded by respiratory membranes known as gill lamellae which have a large surface area that makes breathing easier. Blood vessels also are found around gills.
The lung is also a respiratory organ found in humans. It runs from a windpipe known as the trachea and branches into bronchi which contain the bronchioles. Alveoli ducts contain alveoli sacs and then alveoli which are membranes that enable the breathing process.
Both are similar because they are respiratory organs found in animals with backbones. They are surrounded by blood vessels and membranes that make the breathing process easier.
