Capillaries. The diffusion of nutrients, oxygen, carbon dioxide and wastes take place in the capillaries. If you want to be more specific, it would be the venous ends of the capillaries where carbon dioxide enters the blood.
Depending on the levels of hydrogen ions, carbon dioxide is converted into bicarbonate in the blood
It is carbon dioxide which is collected from different organs of the body by blood

It is part of the reproductive system. it is the opening to the birth canal
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
Alveoli.
Oxygen (O2) enters the blood through inhalation and is circulated throughout the body. Carbon Dioxide (CO2) is filtered out of the blood as a waste product and exhaled.
It is carbon dioxide which is collected from different organs of the body by blood
The rate at which carbon dioxide enters the cell is determined by the concentration of carbon dioxide on each side of the membrane. Carbon dioxide crosses the plasma membrane by simple diffusion.
