Question
Briefly describe how the following affect total body water:
Body size:
Environmental temperature:
Solution
Body Size: The total body water is directly proportional to the body size. Larger individuals have more body mass, thus more cells, and therefore more water in their bodies. This is because water is found in every cell of the body. It's also important to note that body composition plays a role as well. Muscle tissue contains a higher percentage of water than fat tissue, so individuals with more muscle mass will have a higher total body water.
Environmental Temperature: Environmental temperature can affect the total body water by influencing the rate of water loss from the body. In hot environments, the body sweats more to cool down, which leads to a higher rate of water loss. If this water is not replaced, it can lead to dehydration. On the other hand, in cold environments, the body doesn't sweat as much, so water loss is reduced. However, water can still be lost through respiration and the increased production of urine that can occur in cold conditions. Therefore, regardless of the temperature, it's important to stay hydrated to maintain the appropriate total body water.
