Peptide hormones are a class of peptides that are secreted into the blood stream and have endocrine functions in living animals. ..." (Anti diuretic hormone, 8 October 2008).
The activation process of ADH is done by water receptors and these water receptors are located in extracellular fluid as well as intracellular fluid. It is very important to maintain water homeostasis and this is done by controlling two things namely, the osomolality and the intravascular blood volume. In the body of a human being water is lost by various activities such as breathing, which contributes the maximum in loss of water in a human body other activities include sweating, urination etc. "While several of these processes occur autonomic in healthy individuals, body water homeostasis is tightly controlled by regulating both water intake (drinking) and urinary water excretion. Changes in intravascular blood volume are sensed by vascular volume- and baroreceptors, which regulate the release of the anti diuretic hormone arginine vasopressin (AVP)." (Physiology, 8 October 2008)

Re-absorption of water increases blood volume and concentrates the urine." (ADH, 8 October 2008). As discussed earlier in the paper that hypothalamus maintains a balance in the body and this is exactly where hypothalamus comes into effect, when hypothalamus detects a decrease in water level in blood, ADH is secreted, and the same is secreted by the posterior pituitary.
ADH mainly targets the kidneys because the ultimate role of kidneys is to make sure that there is a good balance of the fluids in the body. The main function of ADH is to concentrate the urine and make sure that there is less of amount of water loss which is taking place in the body, it reduces the urine volume and prevents water loss from the body. Caffeine is responsible for reducing the vasopressin secretion, "Vasopressin is secreted from the posterior pituitary gland in response to reductions in plasma volume and in response to increases in the plasma osomolality" (Vasopressin, 8 October 2008). When caffeine is in took, it results in the reduction of vasopressin secretion, which ultimately means that the water re absorption gets reduced in the body and the output of urine becomes very frequent. The same can be understood with the help of an example, if we consume more coffee which has high levels of caffeine in it, we tend to become restless and the anxiety level in our body tends to rise to an alarmingly high level, all this happens because of the presence of caffeine in coffee, the ultimate result of consuming more coffee will be dehydration because of the levels of caffeine present in the same. Caffeine causes the body to lose excessive amount of water and if coffee is consumed excessively, dehydration becomes inevitable.

The Chinese emperor Shennong, according to Chinese legend, reigned in around 3000 BCE and found out that when leaves fell into boiling water a “fragrant and restorative drink resulted”(Yu, 35) leading historians to believe that this also aided in the discovery of tea/caffeine use for regular usage. In 900 BCE, “The Greek historian Homer mentions a bitter drink that is capable of warding off sleep. This was probably strong brewed tea.” (Unknown, 14) Coffee was discovered later on in the 9th century by a goat herder who observed his goats eating berries from a tree that made them more alert and awake.

Kidney Dialysis and Kidney Transplantation

..."A Comparison of Kidney Dialysis and Kidney Transplantation" INTRODUCTION Kidney failure is one of the most common and most lethal type of organ failure. The kidneys, a pair of bean-shaped organs acts as filters for blood and other body fluids. Without the kidneys, the body will succumb to the toxins it encounters everyday. Toxins filtered by the kidneys are excreted out of the body through the urinary system mixed with urine. Toxins and other harmful substances, come from various sources such as the environment (in the air, water and other environmental factors), from our food especially those laced with high...

The effect of freezing water

... Common Effects of Freezing Water Water starts contracting at 39 degrees and expansion process follows. As the temperatures go lower, water molecules become slower in their movement and spread further apart. Colder than that and they now form a pattern., when water freezes into ice, so many things happen, like rain turning into snow or a lake completely turning into ice. The first effect occurs when water reaches its freezing point, when water temperature drops to 32 degrees, it starts becoming ice. However, when impurities are added to the water, the temperatures go below 32 degrees. This is the first effect caused when water is at its initial freezing stages. The transition phase is the next stage in the process, and it occurs... at the...

Absorption Spectroscopy

...Determination of concentration of Allura Red in sparkling fruit water The purpose of this experiment was to determine the amount of Allura Red dye present in sparkling fruit water and then comparing it with the dye’s LD50 published in literature. A sample of the water with the dye was analyzed using absorption spectroscopy. It was found that 0.06531 grams of Allura Red dye was present in the sample of sparkling fruit water. Comparing it with the LD50 (6-10g/kg body weight), it was found that the level of Allura Red dye in the water is within normal levels.
