Oxygen must diffuse through the cell membranes of the alveoli in the lungs. This diffusion depends upon the concentration gradient between the air in the lungs and the dissolved oxygen in the blood moving through the lung tissue. Air is only about 20% oxygen, so in order to load up the blood with oxygen, there must be lots of surface area for diffusion from the air.
To allow for huge amounts of oxygenated blood be diffused from the alveoli to a capillary network. and for CO2 to travel form the blood capillary network into the alveoli. The surface area is huge because massive amounts of O2 and CO2 are diffused each minute= around 6- 10 liters.
Whilst exercising you can use around 100 liters of oxygen per minute.
Human lungs have a large surface area so that gas exchange can take place more efficiently and effectively. Carbon dioxide must come out of the blood and into the inspired air while oxygen must be absorbed by the blood from that air. A larger surface area means more area (more places) for gas exchange to take place.
Alveoli in the lungs increase the overall surface area of the lungs, to encourage more diffusion to take place, so that a greater volume of oxygen / carbon dioxide can be transferred out of / into the lungs.
it need room for oxygen to travel in an out.
Inside each lung are millions of tiny sacs, called alveoli. These structures greatly increase the surface area of the lungs, which helps to maximise the volume of oxygen and carbon dioxide that diffuses to and from the lungs.
Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism. For unicellular organisms the respiratory surface is governed by Fick's law, which determines that respiratory surfaces must have:a large surface areaa thin permeable surfacea moist exchange surface.
Yes
it all what you have in your body lol
A respiratory surface is located anywhere in an animal or human being where gas exchange occurs. A respiratory surface is located anywhere in an animal or human being where gas exchange occurs.

large area
Respiratory surface is the region where gaseous exchange occur. It includes respiratory bronchiole, alveolar duct and alveolus. Large surface surface is needed the increase the diffusion rate of gaseous. Respiratory surface also exhibit other properties such as moist and only one-cell thick. Nika G.

The large surface area of the small intestine is achieved by a combination of anatomical features such as the plicae circularis, the vili, and the microvilli.

These two organs are the lungs.The lungs are these two organs.
Thremoregulation is easily achieved in large animal as they are able to retain the heat gained. In small animal the surface area is large as compares to their volume and hence gain or loose heat faster. large animal having smaller surface area as compared to their volume gain heat slower.
The larynx, also known as the voice box, is the part of the respiratory system responsible for producing sound and enabling speech. It contains the vocal cords, which vibrate as air passes through, producing sound waves that we perceive as speech. The manipulation of airflow and tension in the vocal cords helps create different pitches and tones.
