Which is the largest organ that releases water and carbon dioxide through sweat glands?

The skin is the largest organ in the human body and plays a crucial role in the process of thermoregulation and waste elimination. One of its primary functions is to regulate body temperature through the secretion of sweat via sweat glands. When the body overheats, sweat glands release water, which evaporates off the skin surface, helping to cool the body.

In addition to releasing water, sweat also contains small amounts of carbon dioxide, along with electrolytes and other metabolic wastes. This dual function of the skin in releasing water and some carbon dioxide makes it an integral part of the body's overall homeostasis. The skin's extensive surface area allows for significant evaporative loss, underscoring its role as the largest organ responsible for these processes.

Other organs, such as the liver, lungs, and kidneys, have different primary functions in the body. The liver is mainly involved in metabolizing nutrients and detoxifying substances; the lungs primarily facilitate gas exchange (oxygen and carbon dioxide) through breathing; and the kidneys filter blood to produce urine, focusing on waste elimination and electrolyte balance. While all these organs play vital roles in maintaining bodily functions and homeostasis, they do not directly release water and carbon dioxide in the same manner as the skin does through sweating.
