Within the circulatory system gas exchange happens at two places. First within the lungs where it picks up oxygen and gives up its carbon dioxide. Secondly, within the capillary beds of the tissues to deliver the oxygen (and nutrients) and pick up the carbon dioxide to bring back to the lungs.
lungs
It's the simpler that exist in vertebrates that has gills as the site of gas exchange, wile other organism have a double loop circulatory system that have lungs instead of gills.
Usually in the body, it is only in the lungs or the respiratory system and nothing else.
The circulatory acts as a transportation system because the hemoglobin on red blood cells transports the gas carbon dioxide back to the heart and lungs for exchange, then picks up oxygen to transport it back to the cells. Fluid waste is carried in part by blood to the kidneys. Also white blood cells and macrophages zoom to areas of infection to clear the body of germs.
The circulatory system is like the gas/water company, supplying energy sources to all of your cells.
gas exchange occurs between pulmonary capillaries and the alveoli in the lungs.
it occurs through the heart
In the lungs.
Respiration.
The respiratory and circulatory system connect in the lungs. At the alveoli, the air sacs are wrapped closely by capillaries to facilitate gas exchange.
No both of them are different but they meet each other in lungs where,exchange of gas takes place.

The respiratory system and the circulatory system
The alveoli at the end of bronchioles allow gas exchange to occur.
provides a large surface area for exchange in oxygen and gas?
they have a closed circulatory sytsem:]yur welcome..... Sorry, this answer is very incorrect. A closed circulatory system means that the blood is contained within blood vessels, which the heart is able to pump/move through the tissues for very efficient gas exchange. Sponges DO NOT have this. In fact sponges do not even technically have a circulatory system at all, gas exchange is achieved by diffusion from the outer cells. So this means that sponges do not have an open or a closed circulatory system, because they don't have one at all.
Amphibians use their lungs, and use their thin skin when its moist.
The respiratory system functions in gas exchange. In doing so, it works closely with the circulatory system, and is aided by the nervous, muscular and skeletal systems.
