a cell membrane
A cell's contents are enclosed by a bilayer of phospholipid molecules, each of which has a head group attracted to water and a tail repelled by it. This bilayer is called a membrane and regulates traffic into and out of the cell. There are five types of transport across membranes in cells: diffusion, facilitated diffusion, active transport, cotransport and endocytosis/exocytosis.

inhalation and exhalation takes place in respiration.Gas exchange takes place at a respiratory surface-a boundary between the external environment and the interior of the organism.therefore they both are same things.
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.
The exchange that takes place between organs and blood are **** and ********
It takes place between the alveoli and the blood capillaries
they use their stomata to exchange gases with the environment by taking in carbon dioxide and releasing oxygen and water vapor into the air

Our body is made up of prokaryotic cells. These cells are not in the contact with the environment. So the process of diffussion cant make any difference in exchange of gasses between the multicellular boy and environment.
Capillaries
External Respiration-the process of first inhaling oxygen (02) and then proceeding to EXHALING the inhaled oxygen in the lungs in the form of carbon dioxide (C02) into the environment, then repeating the process all over again. (the entire process is commonly known as cellular respiration.)
They are the place where the capillaries are closest to the environment in order to exchange gases such as oxygen and carbon dioxide.

The exchange of gas refers to the process where gases are transferred between two materials or systems. In biological terms, this often involves the exchange of gases like oxygen and carbon dioxide in respiration. In chemistry, it can involve the exchange of gases in reactions or the movement of gases between different phases.
Gas exchange between the body and the environment occurs in the lungs.
