The organ that excretes Urea compounds are the kidneys, BUT they do not excrete HEAT. No organ of the human body EXCRETES heat.
Sweat is the result of the body's thermoregulation function, helping to regulate body temperature by cooling it down when it gets too hot.
Vacuoles merge with the cell membrane and then open
