The human body consists of a number of systems having their own importance and contribution towards keeping human beings alive. As blood flows through the body, waste products are deposited into the bloodstream that needs to be removed. The system that does this is the ‘Urinary system’ also known as the ‘Renal system’. It is made up of two kidneys, two ureters, a urinary bladder and a urethra that produce, store and then excrete urine out of the body. For the purpose of this assignment the structure and functions of the urinary system will be explored focusing on the kidneys, in order to explain the importance of maintaining homeostasis. Homeostasis is the regulation of internal processes and substances that maintain a constant internal environment within the body.

The kidneys lie on the posterior abdominal wall, with one on each side of the vertebral column, and are held in position by a mass of fat called ‘Adipose’. (, 1997). Kidneys are the primary organs of the urinary system that filters waste, water and electrolytes from the blood forming urine, through a continuous process called ‘Filtration’. (, 1997). Each kidney has millions of nephrons, these are the functional units of the kidneys where filtration takes place. (Freudenrich, 1997). Nephrons have three functions known as Ultrafiltration, Selective reabsorption and tubular secretion. They are lined with a cellular membrane called ‘Microvilli’, this increases the surface area within the tubule to enable substances to secrete and reabsorb the filtrate. (, 1999)

The formation of urine is initiated when blood is taken to the kidney via the renal artery. As blood flows from the renal artery through the afferent arteriole to the capill...

Catheter Associated Urinary Tract Infections Essay

- “Catheter associated urinary tract infections (CAUTI), are one of the most frequently reported hospital acquired infections” (Gray, Skinner, & Kaler, 2016, p. 301). There is a growing concern over multi-drug resistance infections and how they are related to CAUTIs (Gray, Skinner, & Kaler, 2016). The implementation of a CAUTI bundle, which is a collection of 3-5 interventions, should assist in lowering the incidence of such infections (Gray, Skinner, & Kaler, 2016). The PICOT question, regarding the effect of CAUTI bundles on infection rates, will help to determine if the evidence shows that the use of the bundles can decrease the number of infections in adult patients....   [tags: Urinary tract infection, Urinary catheterization]
