Waste products must be removed from the body. If they are not, they will increase in concentration and may interfere with chemical reactions or damage cells. Waste products that must be removed include carbon dioxide and urea.
Waste Product Why is it produced? How is it removed?
Carbon Dioxide It is a product of Areobic Respiration Through the Lungs when we breath out.
Urea is produced in the liver when excess amino acids are broken down,the kidneys remove it from the blood and make urine, which is stored in the bladder temporarily.
Water enters the body through food and drink. It is also a product of aerobic respiration in cells. If the amount of water in the body is wrong, cells can be damaged because too much water enters or leaves them.
