Answer:
The odd organ out in this list; skin, heart, lungs, liver, kidney, is the heart.
Explanation:
The reason the heart becomes odd one out is that among all the organs in the list only the heart does not perform and excretory role.
The function of the heart is to pump oxygenated blood around the body.
Excretory roles of the organs given:
Lungs - the lungs remove carbon (IV) oxide from the body. Carbon (IV) oxide is the by product of cellular metabolic process.
Skin - the skin excretes sweat from the body. Sweat is composed of excess salt, water and urea.
Kidneys - kidneys excrete urea, excess salt and electrolytes by forming urine which is then eliminated out through the urinary tract.
Liver - the liver excretes bile, metabolic waste, cholesterol, steroid hormones and metabolic waste of drugs
