It's AumSum Time. What if we Drink only Seawater? Naahhh. I only drink Chocolate Milkshake. Oh AumSum. On an average seawater has salinity of about
3.5%. When we drink seawater, water as well as excess
salt get absorbed in our blood. One of the functions of our kidneys is to
remove this excess salt from our blood. But urine produced by kidneys has a salt concentration. Which is less than the 3.5% of that of sea-water. Hence it needs more water to remove all the
excess salt. As a result, we feel thirsty after drinking
seawater. Excess seawater consumption can lead to dehydration. Secondly, excess drinking of seawater. Will also hinder the blood purifying process
of our kidneys. How? Because solute concentration inside the filtering
units of our kidneys. Will be lower than that of the highly saline blood. Hence, due to osmosis, blood doesn't get purified..
