You have barile?
Lungs have hierarchical structure which minimizes volume but maximises surface area
Aveoli are the smallest units of structure and are the site of gaseous exchange:
- They are circular = max surface area for min volume
- Their most surfaces faciliate the exchange of gases
- They have extensive blood supply which also faciliate the exchange
large area
The size of your respiratory system depends on how big you are. It gradually gets larger as you grow from an infant to an adult.
The surface area of a mammalian respiratory system is large primarily due to the presence of numerous alveoli in the lungs, which are tiny air sacs that greatly increase the surface area available for gas exchange. This extensive surface area allows for more efficient absorption of oxygen and the expulsion of carbon dioxide. Additionally, the highly vascularized nature of the alveoli facilitates swift diffusion of gases between the air and blood, optimizing respiratory efficiency. Overall, this adaptation is crucial for meeting the metabolic demands of mammals.
If the surface area of the organism is small, then there is no problem with getting all the oxygen needed. If the surface area of the organism is large, therefore a special respiratory surface is needed. An example is lungs, gills. The ratio of surface area to volume in a small organism is greater than the ratio in a large organism.
thin and moist, with a large surface area and a large concentration gradient.
A decrease in the surface area of the respiratory membrane will result in a decrease in gas exchange.
cos day breathe in H2O innit and there trachea is more complex and blood vessels spread out on the gills to create a bigger surface area. :)
Black Lung disease works by building up coal dust on the surface area of your lungs, therefore reducing the overall surface area of your lungs and reducing the efficency of the lungs.

large area
The lungs have a large surface area due to the presence of millions of tiny air sacs called alveoli. This extensive surface area allows for efficient exchange of oxygen and carbon dioxide between the air in the lungs and the blood in the capillaries. Additionally, the respiratory system is highly vascularized, meaning there are lots of blood vessels surrounding the alveoli, facilitating the absorption of oxygen into the bloodstream.
The smallest functional unit of respiratory system is alveoli. Gaseous exchange takes place here. * The alveoli are attached to bronchules. * bronchules to bronchus. * bronchus to trachea the windpipe.
