Antidiuretic hormone is released by the pituitary gland in the brain to signal the kidneys to retain water. When ADH causes water reabsorption from the kidney tubules‚ the salts and wastes are concentrated in what will eventually be urine. High level of ADH secretion and water retention happen when dehydration causes increase of osmolarity. ADH then travels in the bloodstream to the kidneys where it transforms the kidneys to be more permeable to water by inserting water channels called aquaporins.

Is it ethical to buy or sell human organs? For this ethical issue‚ a college student with heavy financial burdens chooses to sell his kidney to meet his urgent financial needs‚ however‚ he later learns that it is illegal to sell his own kidney. Therefore‚ why should it be illegal for him to sale his own kidney if we have free will over our own bodies and we have the right to what we can or cannot do with our bodies? If medical companies can turn a profit on dead people’s donated bodies and organs

transmit impulses‚ and regulating the balance of blood and body fluids. I believe it is important to monitor your sodium intake in order to stay in good health. Kidneys are the most common concern when too much sodium is being taken in because it can lead to damage to the heart. When there is an excessive amount‚ the kidneys are unable to keep up with the body as they are trying to excrete waste. As sodium is taken in‚ the body retains water to dilute the sodium which leads to an increase in

Glomerulonephritis The kidney performs many functions which include regulation of extracellular fluid and blood pressure‚ regulation of osmolarity‚ maintenance of ion balance‚ regulation of pH levels‚ excretion of waste‚ and the production of hormones. Although the kidney performs all these functions‚ the renal disease Glomerulonephritis‚ also known as glomerular nephritis and abbreviated GN relates to the excretion of waste. With this disease‚ the part of your kidney which is called the renal

Maintaining a normal body temperature is crucial for optimal health and is one important aspect of homeostasis. Homeostasis is the body’s ability to balance varying internal conditions within narrow limits despite a constantly changing outside environment (Marieb & Hoehn‚ 2016). When a person is subjected to stimuli‚ which is a change in the variable‚ such as cold weather‚ temperature sensitive receptors in a person’s skin called thermoreceptors‚ detect this change. The receptors then respond providing

Pyelonephritis is an inflammation of the kidney and upper urinary tract that usually results from noncontiguous bacterial infection of the bladder. It is a renal disorder that involves the pyelum‚ pelvis or the parenchymal tissues which commonly known as pyelitis. A more severe form of the disease‚ on the other hand is called urosepsis. The common bacteria that usually found in patient with this disease are E-coli‚ staphylococcus‚ and streptococcus. Most kidney infections result from lower urinary tract

What is chronic kidney disease? Chronic Kidney disease or CKD ‚ is a condition that affects the function of the kidneys and that may progress over time to kidney failure. When the kidneys fail‚ dialysis or kidney transplant is needed to support

Serum creatinine is an important marker of renal health as it is an easily measured byproduct of muscle metabolism that is excreted unchanged by the kidneys. Creatinine itself is produced by a biological system include creatine‚ phosphocreatine or creatine phosphate‚ and adenosine triphosphate “ATP”. Creatine is formed mainly in the liver from the methylation of glycocyamine by S-adenosyl methionine. It is then carried through blood to the other organs‚ muscle‚ and brain‚ where‚ through phosphorylation

Cardiac Catheterization and Kidney Function In many hospitals‚ the use of cardiac catheterization is used to determine if a patient has occluded arteries or grafts. This procedure saves many lives every day and helps prevent myocardial infarctions in many cases. The procedure itself is rather simple and safe for the most part‚ but one thing that many fail to realize is how hard the procedure is on kidney function due to the dye used intra-procedure. According to the NIH‚ kidney damage caused by dye is

Introduction: The issue being discussed is should there be a market in human organs. According to the U.S. Department of Health & Human Services‚ there are currently 86‚445 people waiting for kidney transplantation‚ while only 7‚000 people are available as kidney donors. The debate under construction is of an ethical concern. Is it right or wrong to market human organs? There are opposing positions on this issue. Each has many pretenses and personal and strong rationale for their defense on this
