The main product of cellular respiration is ATP; waste products include carbon dioxide and water.
How do cells excrete?
Excretion is the removal of toxic substances and metabolic waste products. An example of such is cell excretion process. The cell clears its waste products by bringing the waste products close to the cell membrane and then closing the cell membrane around the waste products, isolating it from the rest of the cell.
What is the main aim of excretion?
These chemical reactions produce waste products such as carbon dioxide, water, salts, urea and uric acid. Accumulation of these wastes beyond a level inside the body is harmful to the body. The excretory organs remove these wastes. This process of removal of metabolic waste from the body is known as excretion.

When kidneys are failing, the increased concentration and accumulation of substances in urine lead to a darker color which may be brown, red or purple. The color change is due to abnormal protein or sugar, high levels of red and white blood cells, and high numbers of tube-shaped particles called cellular casts.
Do kidneys clean the blood?
Kidneys are a filter system The main job of the kidneys is to remove waste from the blood and return the cleaned blood back to the body.
Which organ of the body purifies the blood?
