In the lungs - specifically, the alveoli.
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.
respiratory system
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
The circulatory system distributes oxygen to body tissues as it works with the respiratory system. It also helps bring carbon dioxide back to the lungs so that it can be expelled.
The site of respiration is the cells, more specifically, the mitochondria
They exchange water, oxygen and carbon dioxide, as well as nutrient and waste chemical substances between blood and surrounding tissues.

respiratory system
chloplast
The circulatory system imports oxygen and exports waste materials or carbon dioxide. The circulatory system distributes fresh oxygen to the tissues and organs of the body.
the air sacks
The main organ of the circulatory system is the heart, and it pumps blood to the cells of organs and tissues, giving them oxegyn and removing carbon dioxide.
Yes, they do. Just as humans do.

Oxygen and Carbon Dioxide.
This is accomplished by the circulatory system - from the arteries, to the arterioles, down to the tiniest of capillaries, which feed all tissues, including muscle and bone. Exchange finally occurs between the capillary membrane and the cell membrane.
To bring nutrients and oxygen to the tissues and absorbing carbon dioxide and other waste products from them.
