The brain is about 80% water, more than any other organ.
The skin is the largest organ in the human body. The biggest "component" in the body is water.
The highest level of organization that consists of all organ systems of the body is organismal.
ADH acts on the kidneys, but not to prevent water retention. ADH is a hormone that is released when the body is low on water to help the body retain water. It does this by helping to concentrate the urine and reducing urine volume. For more information, visit the Related Link.
Kidney
heart This is incorrect. Sweat is produced by sweat glands in the skin.
No. The organ system is.

The water displaced by the body is equal to its volume.
A body which is totally submerged in a liquid displaces a volume of water equal to the volume of the body.
Blood. You have roughly 10 pints of blood in your body. No other fluid in your body reaches that volume so the blood wins.

The kidneys are the major organ of homeostasis. They control the water volume in blood by measuring the salt content of the filtrate as it produces urine. If the concentration is too low it tells the kidneys to release renin, which releases angiotensin II, which then releases aldosterone. This then tells the kidneys to retain more salt which increases the water retention in the body. The negative feedback chemical to this is atrial natriuretic hormone release by the heart. There is no organ that measures and corrects the water volume in the body. Water volume is controlled by salt concentration.
No, it isn't.
In order to measure volume, one normally sees how much water it displaces. If the body floats, the water displaced will be equal to the weight of the body, not the volume. It will be necessary to force the body down so that it is totally submerged. If there is an anchor and chain below the surface, the water displaced when the body is attached and submerged will have the same volume as the body.
