Homeostatic Imbalance
Regina Gilman
A&P II
May 6, 2015

To function properly the body has systems to maintain homeostasis, the maintenance of a steady internal state, despite changes in external or internal conditions. Homeostasis is maintained through negative feedback and positive feedback systems. Homeostasis enables body systems of a human being to function as expected because of proper temperature regulation. When someone has to be placed on dialysis their body goes through a process that waste products are excreted from our bodies artificially by a process called diffusion. This process of removal of waste products in a healthy person is facilitated by kidneys. People that is diagnosed with kidney failure experiences problems with waste removal this is where dialysis comes into place. People with renal failure and are in the process of dialysis have been known to have several homeostatic imbalances. One of the major effects is electrolyte imbalance and this usually lead to different types of conditions. One of these condition known as hyperkalemia may occur if calcium levels exceed the amount that can be excreted. Another condition that may arise in the course of dialysis is arrhythmias (Elsevier,2013). This can lead to electrolyte imbalance and changes in homeostasis of acid and base. Other issues that can arise related to increased removal of fluid volumes include low blood pressure, cramping as well as muscle spasms. During dialysis, there is a high posibility of damage to the normal net filtration pressure due to increased membrane permeability and this as well leads to homeostatic imbalance.
Dialysis causes biochemical and toxic effects as a result of hemolysis and this may destroy red blood cells. Other homeostatic imbalances include thrombosis, dehydration, and hypertension. Since most of our body systems functions

    1) Kidneys – The left kidney is higher than the right kidney due to the position of the liver. Filters waste products of metabolism that collect in the blood. They remove waste from the blood to form urine. The kidneys maintain balance between retention and excretion of fluids ( play key role in fluid and electrolyte balance). The normal adult urine output is 1200 to 1500 ml/ day. An output less than 30 ml/hr indicates possible circulatory, blood volume or renal alterations. Erythropoietin functions within the bone marrow to stimulate RBC production and maturation. Patients with chronic kidney conditions cannot produce sufficient quantities of this hormone are prone to anemia. The kidneys affect calcium and phosphate regulation by producing a substance that converts vitamin D. Patients with chronic alteration in the kidney fuction do not make sufficient amounts of the active vitamin D. They are prone to develop renal bone disease resulting from impaired calcium absorption. Renal hormones affect blood pressure regulation, renal ischemia (decreased blood supply), and renin is released from juxtaglomerular cells. Renin functions as an enzyme to convert angiotensinogen (a substance synthesized by the liver) into angiotension1. Angiotensin 1 is converted to angiotensin 2 in the lungs. Angiotensin 2 causes vasoconstriction and stimulates aldosterone released from the adrenal cortex. Aldosterone causes retention of water, which increases blood volume. The kidneys also produce prostaglandin E2 and prostacyclin, which help maintain renal blood flow through vasodilation. These mechanisms increase arterial blood pressure and renal blood flow.…

    The body responds to this type of stress by initially going into shock which is caused by a decrease in blood pressure. The endocrine system will respond by releasing hormones that will increase the blood glucose and amino acid levels. The body will then enter a hypercatabolic state that results in the body destroying healthy tissue for glucose and amino acids. Skeletal trauma, severe infection, and severe burns can result in a pathological stress response. A pathological stress response can lead to multiple organ failure even when managed appropriately, which causes death in half of intensive care patients. The kidneys are one of the organs that can fail first when the body is pathologically stressed. Kidneys are important for regulating blood pressure, activating vitamin D, filtering and removing waste from the blood, and making hormones that are needed for production of red blood cells. If a person has chronic kidney disease then the kidneys will cease to function properly, and can result in dialysis or even a need for kidney…

    Healthy kidneys clean the blood by filtering out extra water and wastes. They also make hormones that keep your bones strong and blood healthy. When both of your kidneys fail, your body holds fluid. Your blood pressure rises. Harmful wastes build up in your body. Your body doesn't make enough red blood cells. You develop fatigue, nausea, and loss of appetite. When this happens, treatment is needed to replace the work of your failed kidneys.…

    The renal system performs a vital role in homeostasis. The kidneys’ ability to retain valuable constituents and expel metabolic wastes from the body enables this system to regulate the volume, osmolarity, and pH of body’s internal fluid environment (Sherwood, 2007, p. 511). The functional unit of the kidney, referred to as the nephron, is composed of both tubular components—Bowman’s capsule proximal tubule, loop of Henle, the distal tubule, and the collecting duct—and vascular components—afferent arteriole, glomerulus, efferent arteriole, and peritubular capillaries (Sherwood, 2007, p. 514).…

    Here, acid-base balance and waste removal is achieved. This process is achieved by passive diffusion that involves the movement of molecules from the peritubular capillaries to the interstitial fluid within the nephron. It also involves active transport involving the movement of molecules via ATPase pumps that transport the substance through the renal epithelial cell into the lumen of the nephron (Boundless, 2016). This process differs from the reabsorption process in that it filters and cleans substances form the blood and do not retain them. Some of these substances include, potassium ions, hydrogen ions, urea, hormones, and others. Failure of the kidney to undergo this process allows wastes to be backed up in the system which endangers the organ systems in the…

    Each year hundreds of thousands of patients begin dialysis due to kidney failure. A review of diseases that cause kidney failure can help build an understanding. Glomerulonephritis, polycystic kidney disease and tumors are some of the many diseases that may affect the kidney. They have similarities between them in terms of symptoms and may have an association with malignancy. The epidemiology, pathology, and pathogenesis of these diseases are of importance to help differentiate between them.…

    The kidney is one of the most important organs in our body; it removes waste products from the blood by excreting them into the urine. If a person experiences kidney failure, waste products can’t pass out of the blood, which causes waste to build up in their bodies. While a patient can choose to replace their kidney with a working one, dialysis is also an option in cases of kidney shortage. Dialysis provides the same functions a kidney does. It clinically purifies the blood as a replacement for the lost kidney, by separating the particles in a liquid of the basis of differences in their ability to pass through a membrane.…
