There is a system of the body called the Excretory System.
Explanation:
The organs of this system get rid of a certain waste. The skin gets rid of sweat. The lungs get rid of carbon dioxide and water vapor. The liver gets rid of bile, which, in addition to breaking down fats, is partially made up of the breakdown of red blood cells. The kidneys get rid of toxins from the blood. The large intestine gets rid of undigested food. in this way the Dermal, Respiratory, Lymphatic, Urinary, and Digestive Systems work together to get rid of wastes.
Exhaling removes waste from the body by taking out the toxins that we breath in. The Respiratory System gets the oxygen and removes the carbon out of the lungs. Trees also help us breath in oxygen because it absorb carbon dioxide and then releases oxygen!
Diffusion refers to the process that describes the movement of fluid from areas of high concentration to low concentration. Osmosis is the opposite of diffusion and refers to the movememnt of low concentrations to high.
