The integument system is the skin and does have the ability to help remove waste. Salts, water, urea and ammonia are lost through the skin.
The digestive system absorbs nutrients from the food and these nutrients are carried to their eventual targets (liver, muscle and fat tissue) within the circulatory system. Digestion requires that the body redirect blood flow towards the digestive system in order to adequately handle the metabolic needs of digestion as well.
The respiratory system brings the oxygen inand out of the bodywhich the circulatory system takes theoxygen through.
excretory system are responsible for waste excretion, it works with circulatory system (which aid delivery of nutrients, blood, oxygen and the dispose of waste through excretory system), integument system which include skin and in the skin we can find the sweet glands which also excrete waste in the form of sweat.
