it wastes
Red blood cells carry most carbon dioxide wastes away from the cells of the body.
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.
carbon dioxide and ammonia
Oxygen, Carbon Dioxide, and Nitrogen
Yes. But nitrogen is inactive.
Carbon Dioxide Carbon dioxide (along with any dissolved gases) are transported through the blood to the lungs.
Mostly nitrogen, oxygen, and carbon dioxide.
Yes, in a way. They take out the carbon dioxide from the blood and put the oxygen back in the blood. The sole purpose of the blood is to get oxygen from the lungs and bring it to other body parts and take the carbon dioxide back to the lungs.
Not free gases, but there are several that can be dissolved in blood: nitrogen, oxygen, carbon dioxide, carbon monoxide, even sulfur dioxide and gaseous hydrogen compounds.
The heart pumps blood throughout the body to exchange nutrients/wastes and oxygen/carbon dioxide.
The red blood cells store and transport nutrients and wastes throughout the body. Nutrients include food and water molecules along with oxygen while wastes are carbon dioxide.
The blood carries both nutrients (food) and wastes to and from cells. At the lungs carbon dioxide is exchanged for oxygen and at the kidneys blood is filtered and wastes and some water is lost. Most of the water is retained.
