Gas exchange occurs when oxygen from the air diffuses into alveoli in the lungs and then into the bloodstream, while carbon dioxide simultaneously diffuses from the bloodstream into the alveoli to be exhaled. This process allows the body to obtain oxygen for cellular respiration and remove carbon dioxide waste.
The reason for this is that oxygen and carbon dioxide need to diffuse through this membrane very quickly to re-oxygenate the blood. The thicker the barrier, the longer the process, and since breathing is rather rapid it needs to happen fast.
Alveoli are tiny air sacs in the lungs where oxygen is taken in from the air we breathe and carbon dioxide is released from the blood. They have thin walls that allow for gas exchange between the air and the blood stream, ensuring that oxygen is absorbed and carbon dioxide is expelled from the body during respiration. This process is essential for providing the body with the oxygen it needs for energy production.
The alveoli are the structures in the respiratory system responsible for the exchange of oxygen and carbon dioxide. They are located in the lungs and have a thin membrane that allows for gases to be exchanged with the blood vessels.
The process of ventilation begins at the nose or mouth, where air is inhaled. From there, the air travels down the trachea, which branches into the bronchi and further into smaller bronchioles within the lungs. This pathway allows for the exchange of gases, primarily oxygen and carbon dioxide, to occur in the alveoli, the tiny air sacs in the lungs.
The process that allows oxygen and carbon dioxide to transfer is called respiration. In the lungs, oxygen is taken in from the air we breathe and is exchanged for carbon dioxide that is then exhaled. This gas exchange occurs in the alveoli, tiny air sacs in the lungs, where oxygen enters the bloodstream and carbon dioxide leaves it.
Diffusion is the process that allows the exchange of oxygen and carbon dioxide in the alveoli. This process is one of passive transport.

It happens in the alveoli of the lungs

Diffusion
External respiration refers to the exchange of oxygen and carbon dioxide between the lungs and the blood in the pulmonary capillaries. This process allows for oxygen to be taken up by the blood and carbon dioxide to be removed from it.
Alveoli are tiny air sacs in the lungs where oxygen is taken in from the air we breathe and carbon dioxide is released from the blood. They have thin walls that allow for gas exchange between the air and the blood stream, ensuring that oxygen is absorbed and carbon dioxide is expelled from the body during respiration. This process is essential for providing the body with the oxygen it needs for energy production.
The alveoli are the sites of respiration: the oxygen in them provided by the inhaled air diffuses into the blood cells that flow through the capillaries. Carbon dioxide diffuses out of the blood and into the alveoli so it can be exhaled. The capillaries provide a way for the blood to reach the alveoli. Hope this helps
The tiniest tubes in the circulatory system, known as capillaries, are closely related to the air sacs in the lungs, called alveoli. Capillaries surround the alveoli and facilitate the exchange of oxygen and carbon dioxide between the air in the alveoli and the blood. This process allows oxygen to enter the bloodstream while carbon dioxide is expelled from the blood, highlighting the interconnectedness of the respiratory and circulatory systems in maintaining body oxygenation.
The function of the alveoli is to allow gas exchange with the blood and lungs. It takes in the carbon dioxide and then diffuses it.
