The respiratory system increases the rate of gaseous diffusion through several mechanisms. Primarily, it maximizes the surface area for gas exchange by utilizing alveoli, which are tiny air sacs in the lungs. The thin walls of the alveoli facilitate rapid diffusion of oxygen and carbon dioxide between the air and blood due to the concentration gradients. Additionally, the continuous flow of air during breathing and the circulation of blood enhance the exchange of gases, ensuring that oxygen is efficiently absorbed while carbon dioxide is expelled.

What do the respiratioy system do?
The respiratory system is the anatomical system of an organism that introduces respiratory gases to the interior and performs gas exchange. In humans and other mammals, the anatomical features of the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood.
Which system removes gaseous waste?
The respiratory system removes gaseous waste such as carbon dioxide from the body. This waste is eliminated when we exhale.
How does oxygen moves from the respiratory system to the circulatory system?
by diffusion across a capillary wall
Where does the diffusion take place in the respiratory system?
in the lungs
How does the respiratory system move air to and from gas exchange surfaces?
diffusion
In what organ of the respiratory system is carbon dioxide released in its gaseous form?
The lungs
What role does diffusion play in the Respiratory System and circulatory system?
hai :) it is in your book dont be lazyass.
Where in the respiratory system does gas exhcange occur?
Gas exchange occurs in the alveoli in the respiratory system. The thin-walled structures allow diffusion of gases into and out of the capillaries.
Where in your respiratory system does the exchange of O2 happen?
Gaseous exchange occurs in the alveoli (singular = alveolus) of the lungs.
Diffusion in the respiratory system?
Diffusion in the respiratory system refers to the process by which gases, such as oxygen and carbon dioxide, are exchanged between the lungs and the bloodstream. This occurs at the alveoli, where oxygen from the air diffuses into the blood and carbon dioxide from the blood diffuses into the air. Diffusion occurs because of the concentration gradient of these gases between the alveoli and the blood.
What are the two features of a fish's respiratory system that make the fish efficient in gaseous exchange?

Where is 3 systems in the body where diffusion occurs?
Diffusion occurs in the respiratory system, where oxygen and carbon dioxide exchange happens in the lungs. It also occurs in the digestive system, where nutrients pass through the walls of the small intestine into the bloodstream. Additionally, diffusion takes place in the circulatory system, where gases and nutrients move between blood and tissues at the capillaries.
