  • Addison's Disease Research Paper

    1.What is it? Addison’s disease is a rare hormonal disorder and is a significant deficiency of the hormones that is created in the adrenal cortex. Hormones are chemical messengers that keep the body in balance by regulating functions like reproductions or our emotions. These hormones are produced in the adrenal glands, which is located at the top of each kidney. The adrenal glands has an outer part known as the cortex and an inner part known as the medulla. Adrenal glands produce epinephrine, also known as adrenaline, that is created during the time of stress that in response will raise blood flow and pulse rate.

  • Aldosterone Research Paper

    The body uses 3 different hormones to regulate the loss of fluid; antidiuretic hormone, aldosterone and atrial natriuretic peptide. Antidiuretic hormone and aldosterone slow down fluid loss from urine. The antidiuretic hormone will do this by allowing water in the urine to be taken back into the body in a specific area of the kidney. This allows more water to return to the bloodstream which in tur means urine concentration will rise and water loss will be reduced. Aldosterone’s main role in the…

  • Angiotensin-Aldosterone System: A Summary

    Angiotensin Converting Enzyme (ACE) inhibitors lower blood pressure and produce vasodilation by inhibiting ACE – blocking the conversion of angiotensin I to angiotensin II, key mediators of the Renin-Angiotensin-Aldosterone System (RAAS). RAAS is the main mechanism for controlling BP. Angiotensin II is a vasoconstrictor and works by binding to angiotensin I receptors on smooth muscle – these are joined to a Gq protein and the IP3 signal transduction pathway. ACE usually breaks down bradykinin.…

  • Ecg Case Study

    Will the nurse's mistake increase or decrease the "saltiness" of the interstitial fluid? The nurse's mistake will increase 'saltiness' of the interstitial fluid. Sodium dissolves in plasma and is filtered into the interstitial fluid through capillary walls. As a result, the interstitial fluid will therefore increase. 6. What symptoms might result from hypernatremia? Symptoms that might result from hypernatremia are weakness, nausea, confusion, thirst due to stimulation of the thirst center in…

  • Mr Penzey Case Study Essay

    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 hormone helps in regulating the blood pressure. Whenever there is a decrease in blood flow to the kidneys, this system is activated. The typical flow of these hormones is renin release angiotensin, which then releases…

  • Anti Diuretic Hormone Lab Report

    Since all individuals will begin the experiment in a slightly dehydrated state there will be high levels of Anti diuretic hormone and aldosterone, ANP levels on the other hand will be at a reduced level. We will test four different conditions during the experiment, continued dehydration, consumption of water, coke and Gatorade. All of these conditions will cause a shift in various aspects of homeostasis and will require compensation from the body through the renal system. The consumption of…

  • Essay On Addison's Disease

    Addison’s Disease is a disease when adrenal glands don’t produce enough hormones. The adrenal glands also do not produce enough cortisol and aldosterone. Cortisol is a steroid hormone and aldosterone helps regulate blood pressure. There are less than 200,000 cases in the U.S per year, so it is a rare disease. It affects both sexes of all ages, and affects 1 in 100,000 people. Dr. Thomas Addison discovered the disease in 1849, and named it after himself. Addison’s Disease can be life-threatening.…

  • Mr Penzey Case Study

    What did the genetic results suggest about Mr. Penzey’s condition? The mutation on the agarose gel showed the presence of a chimeric 11-β-hyroxylase gene which caused an overproduction of the enzyme aldosterone synthase. How is this enzyme involved in the function of ACTH, aldosterone and cortisol? How do these hormones affect the homeostasis of blood pressure? The CYP11B1 gene provides instructions for making an enzyme called 11-beta-hydroxylase. This enzyme is found in the adrenal glands,…
