A hydrostatic pressure develops in the capsule because the efferent arteriole is narrower than the afferent arteriole owing to which water, glucose, amino acids, urea and salts enter the capsule from the glomerulus through podocytes (McNaught & Callander, 1975). The second process, i.e. Reabsorption helps to return useful constituents back into the blood stream. Reabsorption takes place in the convoluted tubules as well as in the Loop of Henle. Active Reabsorption takes place in the proximal convoluted tubule where entire glucose, sodium, potassium, uric acid and 75% water is reabsorbed. After this the liquid enters the Loop of Henle where further salts and water are again reabsorbed. Almost 80% of the water Reabsorption takes place in the proximal convoluted tubule and the Loop of Henle by obligatory Reabsorption. It is during Reabsorption that a counter current mechanism occurs and the urine is made hypertonic by regular exchange of sodium ions between the limbs of the Loop of Henle. Next, the urine passes into the distal convoluted tubule where the Reabsorption of water is initiated by a hormone named ADH or Vasopressin. Vasopressin or ADH is released by the posterior pituitary gland and play an important role in regulating the amount of urine formed. Absence of ADH in the distal convoluted tubule decreases Reabsorption of water and hence large amounts of urine is passed whereas increased amount of ADH, increases Reabsorption of water and the quantity of urine passed is much less. The last process is called Tubular secretion which takes place in the distal convoluted tubules and the collecting tubules. Tubular secretion is the opposite mechanism of tubular Reabsorption. Here, potassium ions are secreted to maintain the pH of the blood while sodium is reabsorbed by rennin-angiotensin mechanism (Dunn & Donnelly, 2008, pp79). After this the urine formed is voided through the urethra via the act of micturition. The kidneys not only help in elimination of harmful substances but also play an important role in maintaining blood volume. Kidneys are able to retain water and sodium, owing to hormone vasopressin and rennin-angiotensin mechanism help in regulating the blood volume too. Alcohol consumption is detrimental for the body in more ways than just one. It affects the liver, excretory system, circulatory system, respiratory system and is a major cause of disease such as liver cirrhosis, alcoholic hepatitis, cancer etc (Barclay et al, 2008). Both chronic and acute alcohol consumption is known to have adverse effects on the body especially on the excretory system because it taxes the kidneys heavily. Alcohol consumption impairs the efficiency of the kidneys and disturbs the fluid and electrolytic balance of the body. It has been observed that within half an hour of alcohol consumption, urine is excreted. The increased loss of fluid through urine excretion leads to concentration of the electrolytes present in the blood. This is in fact the major reason that causes dehydration in people who consume alcohol. We are already aware of the fact that urine output depends largely on Anti-Diuretic hormone or Vasopressin. Vasopressin induces fluid conservation by the kidneys thereby concentrating the urine output. In the absence of this effect, the kidneys fail to conserve any fluid because of ...Download file to see next pagesRead More

Chronic Kidney disease

...from the blood, however, when one suffers from loss of kidney function, this process takes time and the result can start showing after some time. When kidney function ceases, water, waste and toxic substances accumulate in the body. These are the substances that are excreted by a normal kidney, which a damaged kidney cannot handle. The major causes of chronic kidney failures are high blood pressure and diabetes, however, the choice of ones lifestyle can also lead to this disease. In Ali’s case, heavy consumption of alcohol and frequent smoking at his age is the main cause to the kidney...

Polycystic Kidney Disease

... are also likely in this form of the disease (NIDDK). Children with autosomal recessive polycystic kidney disease are smaller than other children due to the impaired functioning of their kidneys (NIDDK). These children will also have lower blood cell counts than the normal range (NIDDK). Another problem seen in this disease relates to the valves of the heart. About one in every four people with polycystic kidney disease also has problems with a heart valve and may experience chest pain because of this (NKF). Since clusters of cysts are the central characteristic of this disease, it is not surprising that the cysts can be numerous and very large. With the formation of cysts occurring on the kidneys, the kidneys themselves grow... from their...

Kidney Transplantation

...? Kidney Transplantation - Kidney Transplantation Brief History Kidney Transplantation is a process in which a non-functioning or diseased kidney is replaced with a functioning kidney. The late 1950s saw the development of modern transplantation techniques. The clinical and experimental transplantation was extensively exploited in the early 1950s and the first two decades of the 20th century. Joseph Murray and colleagues performed the first successful renal transplant in 1954 at Boston, USA. With no effective immunosuppressant therapies, Murray was aware that tissue rejection would complicate matters for the recipient;...

Kidney Stones

...?Kidney Stones Kidney stones, known medically as renal lithiasis, are hard, solid deposits made of acid and mineral salts that form within the kidneys. These stones often form when urine becomes too concentrated with dietary minerals, thus allowing these minerals to crystalize and gather into a kidney stone. While both males and females are susceptible to kidney stones, eighty percent of individuals who have been diagnosed with this condition are men (Rao, 2011). This is due to the biological traits of men simply being more predisposed for kidney stones, and because women often pass kidney stones with such ease that many...

Kidney Disease and Dialysis

...Kidney Disease and Dialysis Effects of climate, such as relative humidity, wind, ionization, and barometric pressure, are more subtle and widespread than such obvious climatic hazards as frostbite or heatstroke. Changes in humidity and pressure can trigger arthritic attacks, affect the pain of corns on the feet due to increased pressure against shoes, and have effects on kidneys too. High humidity retards the loss of heat by reducing the evaporative cooling effect of sweating. High temperatures increase the need for water. Under severe conditions like California most people can tolerate a water deficit of 5% of body weight; they become very listless with a 10% deficit, and a 15% water deficit can be...

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 amounts of...

Kidney trafficking

...to bodily disorders that are related with affluence. For example, Type II Diabetes can result from gaining excessive weight. This disease could easily weaken the normal functioning of body organs such as the kidneys. The demand for kidneys has thus increased in many Western nations. Moreover, there are few donors of these precious organs. Many Western hospitals have long waiting lists of patients who have to survive through dialysis until they benefit from an organ. Their desperation spawns the activities of international criminal organizations that deal in the trade of organ transplants. Even though the trade in human organs remains illegal in many nations, the demand for these organs,...

Ethanol effect on kidney

...Both forms of ethanol consumption i.e. acute and chronic have the ability to seriously compromise kidney function, more specifically in juxtaposition with distortion of liver function. Various investigators have studied the alcohol related structural as well as functional changes in the kidney function along with the ability of ethanol to alter the regulation of the composition and the volume of fluids and electrolytes of the body (Curry 60). It has thus been concluded that patients having a considerable proportion of ethanol in their body may experience lower concentrations of various electrolytes in their blood stream....
