The human body is approximately 6570 water The ocean is 335p

The human body is approximately 65-70% water. The ocean is 33.5ppt dissolved salts. If a human were to be submerged in seawater over a long period of time then that person would suffer from dehydration. 1) Explain what type of cellular transport is at work in the scenario above and why the body allows this to happen. 2) What efforts could you take to prepare yourself for prolonged exposure to the sea such as a day at the beach? Why is water balance necessary? Use specific details to support your answer!

Solution

Answer:

1) Due to the process of osmosis, the movement of water from high concentration to low concentration takes place. So chances for dehydration is more in a person submerged in sea water for more time. In this case, the movement of water in the form mositure takes place from human body into sea water.

2) The person should drink enough amount of water, who is exposeing body to sea water for more time. More amount of water in the body makes you rehydrate. Drinking water at regular intervals is the primary thing to be done. Nearly 8 liters of water should be taken every day.

Water is a solvent and major component, water balance is necessary to maintain the osmotic balance in the body, all enzymes and other metabolic function takes place in the presence of water.
