The function of the lungs is gas exchange. They take in external air, absorb the oxygen the body needs, and expels the carbon dioxide that the body produces as waste.
It has many balloon-like sacs that can hold air.
The lungs are like a balloon because they expand and contract as we breathe, similar to how air fills and exits a balloon.
An example of how structure dictates function can be seen in the alveoli of the lungs. These tiny, balloon-like structures have thin walls and a large surface area, which facilitates efficient gas exchange between the air and blood. Their clustered arrangement maximizes contact with capillaries, allowing for optimal oxygen uptake and carbon dioxide removal, illustrating how their unique structure directly supports their primary function in respiration.
An example of the relationship between structure and function in the human body is the design of the alveoli in the lungs. These tiny, balloon-like structures have thin walls and a large surface area, allowing for efficient gas exchange. This structural adaptation enables oxygen to easily diffuse into the blood while carbon dioxide is expelled, directly supporting the function of respiration.
In fish, the structure that performs a function similar to lungs in mammals is the gills. Gills extract oxygen from water as it flows over them, allowing fish to breathe underwater. They facilitate the exchange of gases, enabling fish to take in oxygen and expel carbon dioxide, much like lungs do in terrestrial animals.

Balloon lungs work in the respiratory system by expanding and contracting to help with the exchange of gases. When we breathe in, the lungs inflate like a balloon, allowing oxygen to enter the bloodstream. When we breathe out, the lungs deflate, releasing carbon dioxide. This process helps to bring oxygen to the body's cells and remove waste gases.
The lungs act a bit like baloons. When you breathe in they will inflate, when you breathe out they will deflate. Using a balloon may be useful way to understand this, breathe into the balloon and it will inflate (this is what happens when you breathe in). Next, leave the air out (slowly) and this is what happens your lungs when you breathe out.
The spongy texture of the lungs provides a large surface area for gas exchange, allowing more oxygen to enter the bloodstream and more carbon dioxide to be expelled. If the lungs were empty like a balloon, they would have a smaller surface area and would not be as effective in exchanging gases.
Inhale and exhale.
bronchi is a tube like structure. It carries air to lungs.
