Osmolality of blood increases with dehydration and decreases with overhydration. In normal people, increased osmolarity in the blood will stimulate secretion of antidiuretic hormone (ADH). This will result in increased water reabsorption, more concentrated urine, and less concentrated blood plasma.
Marcus Terentius Varro Quotes. Marcus Terentius Varro (116-27 B.C.) was the greatest Roman scholar and an incredibly prolific writer. It is estimated that he wrote 74 separate works in 620 volumes on all aspects of contemporary learning. Varro was born at Reate in the Sabine country into a family of some means.
In AD 139 Marcus Aurelius was officially made caesar, junior emperor to Antoninus, and in AD 140, at the age of only 18, he was made consul for the first time. Just as there was no doubt whom of his two adopted sons Antoninus favoured, it was clear that the senate, too, preferred Marcus Aurelius. When in AD 161 Antoninus Pius died, the senate sought to make Marcus sole emperor. It was only due to Marcus Aurelius' insistence, reminding the senators of the wills of both Hadrian and Antoninus, that his adoptive brother Verus was made his imperial colleague.
