  • Essay On Kidney Disease

    There are multiple kidney diseases that are known to the Medical world, but there will be a discussion about Henoch Shönlein Purpura today. Many young kids have had this Kidney disease and it is not to be taken lightly. At first it comes off as something simple, and it looks like the victim has probably just pulled a muscle, has a fever or has a stomach ache because they are vomiting but no, that is just the beginning of this horrid kidney disease. There are probably many questions going around now about this disease, how it was discovered, and what it is exactly. The first ever discovery of HSP was in London of 1801 by a doctor named William Heberden, he had reported “that a five year old boy …was seized with pains and swellings in various parts…He sometimes had pains in his belly with vomiting…and the urine was tinged with blood. Presently, the skin of his leg was all over full of bloarthritis, gastrointestinal involvement, kidney inflammation, and purpuraody points” – www.hopkinsvasculitis.org/types-vasculitis/henochschnlein-purpura/ . All of this would later become known as Henoch Shönlein Purpura by Johann Schönlein and his partner Edouard Henoch. As the two found more cases in people they realized that this was not happening in teenagers, adults, or the elder, that this disease is only found in kids. The average kids that they tended to were around five to six years old, but other kids of different ages got this disease as well. The average kid that gets HSP is three…

  • Creatinine Clearance Experiment

    505). Sodium is reabsorbed in the proximal tubule and loop of Henle regardless of sodium load. Aldosterone is the main factor when kidneys determine the rate of sodium reabsorption. Aldosterone causes an increase in sodium reabsorption. Aldosterone is usually secreted by the adrenal cortex when plasma volume is low. It is controlled by angiotensin II, a component of the renin-angiotensin system. Renin, an enzyme that is secreted by the granular cells in the Juxtaglomerular apparatus (JGA),…

  • Paper On Hypertension

    One of the causes on systematic level is renal artery stenosis. This is the narrowing of the arteries that transport blood to the kidney. Since the arteries are narrowed they bring in less blood to the kidney. This causes the kidney to sense a lower blood volume. When this happens the kidney will release the enzyme, Renin. This enzyme will convert angiotensinogen, which is secreted by the liver, to angiotensin I. When the lungs sense angiotensin I in the circulation they will release…

  • Case Study Of Congestive Heart Failure

    Renin secretion is stimulated by decreased blood volume, decreased renal perfusion, sodium and water depletion. Subsequently, renin promotes the conversion of angiotensinogen to angiotensin I. Angiotensin I is then converted to angiotensin II through the angiotensin converting enzyme. Due to angiotensin II being a potent vasoconstrictor, it also stimulates aldosterone secretion leading to sodium and water retention. The subsequent renal retention of sodium and water, coupled with an increase in…

  • Myopia Case Studies

    vascular walls or macula dense cells detect a change and renin is released into the bloodstream. Renin by itself cannot affect blood pressure until it binds with inactive angiotensin and forms angiotensin II through the use of the angiotensin-converting enzyme. The final product of angiotensin II causes blood pressure levels to increase due to blood vessel constriction, as well as the release of aldosterone into the arterial glands which results in sodium and water retention and potassium…

  • Spironolactone Case Study

    Triamterene. This is merely due to the reason that Spironolactone is not as effective or as such not effective at all, therefore explaining why James saw no reduction in his hypertension even after a 4 week course of treatment. Triamterene was also combined with a low sodium diet in an effort to stabilise James’ high blood pressure. A low sodium diet also has the capability to enhance the effectiveness of Triamterene, hence why the combination is offered to patients. 4. Describe how blood…

  • The Human Body: The Circulatory System

    that there is more hemoglobin for oxygen to attach to. This way lactic acid will not build. The kidneys also filter the blood and remove any waste before being returned to the heart. Waste removal is crucial because is balances the pH of the blood and regulates how much potassium, sodium, calcium, magnesium, phosphate, and chloride ions can continue through the blood stream. If there is excess the kidneys will excrete it through urine because too many of these ions can be dangerous to the body.…

  • Mr Penzey Case Study Essay

    This system is known to be one of the longest systems of hormones, as it was discovered about 100 years ago. Renin is an enzyme protein in nature that flows through the kidneys while angiotensin is a hormone that circulates in the bloodstream and constricts the blood vessels. By causing a restriction in the blood vessels, this hormone can increase the blood pressure which ultimately overworks the heart and body (Sahay, & Sahay, 2012). Aldosterone is a hormone produced by the adrenal cortex, this…

    Primary diseases associated with secondary hypertension include disorders of the renal, endocrine, vascular, neurological disorders; pregnancy-induced hypertension, acute stress and drugs or other substances. Specific diseases or disorders include: renin-producing tumors, renal failure, acromegaly, hyperthyroidism, arteriosclerosis, pregnancy, elevated intracranial pressure, quadriplegia, surgery, burns over 9% or more of the body, alcohol withdrawal, oral contraceptives, antihistamines,…

  • Addison Disease Case Study

    (ACTH = adrenocorticotropic hormone.) Significant low results from the initial sample showed hyponatremia with a sodium level of 103mmol/L, hypochloraemia with a chloride level of 64mmol/L and low total CO2 of 19mmol/L. Hyponatremia is the most common initial laboratory finding as cortisol has weak mineralocorticoid activity and it is also required for free water excretion. A loss of aldosterone activity also leads to natriuresis (Munir & Waseem, 2017). Significant high results from the initial…
