Why purification of blood also referred to as gaseous exchange?
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.
Which human body system delivers oxygen nutrients and hormones to cells and carries carbon dioxide ammonia and other wastes away from cells?
circulatory
Where does the exchange of food oxygen and wastes occur?
In the cappilaries...
Which organ gives oxygen to the blood and takes out the carbon dioxide?
Your lungs, as part of the respiratory system, bring oxygen into your body. Nothing removes carbon dioxide though, it's never in your body per se, the oxygen in your blood cells just gets used when your cells travel through your body, then they go to the lungs which in effect just "recharge" them with oxygen again.
What are two wastes that the body must get rid of?
Carbon dioxide and urea
Do capillaries exchange food and oxygen for wastes and carbon dioxide from the tissues?
Yes, they do. Just as humans do.
Blood vessels in the dermis that carry oxygen and food?
Arteries to arterioles to capillaries where exchange occurs. Oxygen and nutrients are exchanged for carbon dioxide and wastes.
What makes the blood flow continuously throughout the body?
The heart pumps blood throughout the body to exchange nutrients/wastes and oxygen/carbon dioxide.
To get oxygen in your system and wastes out.?
Breathing involves getting oxygen into your system and it expels carbon dioxide, which is a waste.
Which body system Transportsneeded materials to the cellsand carrying the wastes away from cells?
The circulatory system - capillaries exchange oxygen for carbon dioxide, as well as transport materials into and out of the cell.
How do oxygen food nutrients and waste exchange in the capillaries?
Pure diffusion ... everything flows from high concentration toward low. No energy is expended in these exchanges.
Why is the carbon dioxide produced in cells during exercise and What evidence supports this?
Because you take oxygen in and when it is used the cells carry the wastes (carbon dioxide)
How do carbon dioxide and nitrogen wastes get into you blood?
it wastes

Carbon dioxide enters the blood at the?
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.
Is a chemical reaction in cells that needs oxygen to release energy and produces carbon dioxide and water as wastes?
Respiration
What are photosynthesis's wastes?
carbon dioxide
