My guess would be oxygen and carbon dioxide.
Exchange among subdivisions of the extracellular fluid (ECF) occurs primarily at the capillaries, where nutrients, gases, and waste products are exchanged between the blood and interstitial fluid. This exchange is facilitated by the thin walls of capillaries and the pressure differences between the blood and surrounding tissues.
Internal Respiration."Internal respiration is the diffusion of gases between blood and interstitial fluid across the endothelial cells of capillary walls."Says my Anatomy Book.
Gaseous exchange takes place in the alveoli in the lungs, Oxygen is inhaled while Carbon dioxide is exhaled.
Gases diffuse most efficiently across a thin membrane or barrier. This is because a thin membrane allows for quicker movement of gas molecules from an area of high concentration to an area of low concentration.
Earthworms have no special respiratory organs. Gases are exchanged through the moist skin and capillaries.
nitrogen and hydrogen
The gases that are exchanged are oxygen and carbon dioxide.
Frogs uses respiratory surfaces which totals to three to exchange gases on its surroundings. The three respiratory surfaces are the skin, its lungs, and the lining of their mouth.
The gases that are exchanged are oxygen and carbon dioxide.
Oxygen and carbon dioxide are the gases exchanged in the lungs during breathing.
your m0m and your dad are the 2 gases that are exchanged in the sacs of air, thank me later so by by
Oxygen and carbon dioxide are the gases exchanged in the lungs during breathing.
alevoli
Lungs.
alveoli
The Chorion
The heart is not where gases are exchanged. This occurs in the lungs.
