The urinary system is made up of a paired kidneys, the bladder, urethra, and the ureters. Kidney plays an important role of maintaining homeostasis by regulating the volume of fluid in the body. It is essential for renal system maintaining homeostasis through regulation of pH, ECF (extracellular fluid) volume, solute concentration, and ion composition in order to preserve a proper fluid volume in the body. The other important functions of renal system are excreting foreign chemicals, toxins, and metabolites out of the body. Besides, it produces renin to promote salt conservation by the kidneys, and produces erythropoietin to stimulate red blood cell production; since the fluid volume may influences by the sodium concentration within body. Furthermore, the renal system involves with gluconeogenesis and activates vitamin D (Sherwood, 2015, pp.492). Nephron, the functional unit of the kidney, allows the production of dilute or concentrated urine. Renal Corpuscles and tubules are two main components of nephron. The renal corpuscle involves with Bowman’s capsule, a double-walled structure, which surrounds glomerular capillaries to capture filtrate of Bowman’s space. Bowman’s space is between the two walls of the capsule, where cell- and protein-free filtrate is modified as it passes through the rest of the nephron.
High glomerular filtration is crucial for the normal renal function. Vasoconstriction and vasodilation of afferent and efferent arterioles are able to increase or decrease blood flow through glomerulus. As blood flows through the glomerulus, the glomerular capillaries filter the protein-free plasma. This contributes to an average net glomerular filtration rate (GFR) of approximately 125 mL/min (Sherwood, 2015, pp.496). Most...

...bjects have an increase in GFR, which means having an increase in creatinine clearance, because of vasoconstriction, while there was no change in GFR in alkalosis subject. Because of excreting out more dilute urine, it is expected that hypotonic subject have a decrease in specific gravity. Alkalosis and control subjects should have an increase in specific gravity because the subject’s urine should become more concentrated overtime but less in volume. It is expected there will have no change in pH for isotonic and hypotonic subjects but an increase in pH for alkalosis subject because only alkalosis subject consumed bicarbonate solution which caused the urine to be more basic. It is hypothesized that sodium clearance of isotonic subject will increase and that of hypotonic and alkalosis subjects will decrease because of the decrease in osmolarity and activation of ANP.

The Function Of The System Essay

- The excretory system is a passive biological system that removes excess, unnecessary materials from the body fluids of an organism, so as to help maintain internal chemical homeostasis and prevent damage to the body. The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state. In humans and other amniotes most of these substances leave the body as urine and to some degree exhalation, mammals also expel them through sweating....   [tags: Kidney, Urine, Ureter, Urinary bladder]

The Urinary System Essay

- The Urinary System How do the urinay system work ?. Your body takes nutrients from food and uses them to maintain all bodily functions including energy and self-repair. After your body has taken what it needs from the food, waste products are left behind in the blood and in the bowel. The urinary system works with the lungs, skin, and intestines--all of which also excrete wastes--to keep the chemicals and water in your body balanced. Adults eliminate about a quart and a half of urine each day. The amount depends on many factors, especially the amounts of fluid and food a person consumes and how much fluid is lost through sweat and breathing....   [tags: science]

The Functions of the Urinary System Essay

- ... The left kidney sits slightly higher than the right due to the position on the right side of the internal cavity of the liver, and on the apex of both kidneys sits an adrenal gland. The adrenal gland releases a number of different hormones directly into the bloodstream including aldosterone, a hormone which controls electrolyte balance within the body and the ability to control sodium levels. Electrolytes come from the food and fluids we take on board. When the fluid levels within the body change, the electrolyte levels change and this can alter the balance of the blood composition, muscle function and other system processes....   [tags: kidneys, organic substances, waste release]

The Gamma Camera Essay

- The gamma camera has been the mainstay treatment pillar in the department of the nuclear medicines in the past four or so decades. When natural radioactivity was discovered by Henry Bequerel in 1896, the development of the nuclear medicine started; a year before the discovery of the X-rays by Wilhelm Rontgen. It was then found that these rays could be used for therapeutic and diagnostic purposes for patients, a process that became a clinical routine in the 1920s. A series of discoveries in the 1940s and 50s in the field of nuclear medicines saw milestones of developments in the department, especially the 1950s....   [tags: Kidney, Ureter, Urinary system, Urinary bladder]

Essay on Urinary Tract Infections

- INTRODUCTION In the human body, there are systems that provide different functions and help the body to operate more efficiently. The urinary system is one in particular designed to help the body remain free of excess that we no longer need. “The urinary tract is the drainage system used for removing wastes and extra water. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. The kidneys are a pair of “bean-shaped” organs, each about the size of a fist. The kidneys are located below the ribs, one on each side of the spine, towards the middle of the back.” (NIDDK, 2013) Every several minutes, your kidneys filter around three ounces of blood, also then removing wa...   [tags: Radionuclide Scan, Catherer]

Kidney Function Essay

- Kidney Function Introduction and definition of terms: The kidneys are the main organs in the urinary system. They filter waste products out of blood from the renal artery. These are then excreted. Useful solutes are reabsorbed into the blood. They also have a major homeostatic role in the body, and help to control the water content (osmoregulation) and pH of the blood. Homeostasis is the maintenance of a constant internal environment within a living organism. Excretion is the removal from the body of waste products made in the cells during metabolism....   [tags: Papers]
