Homeostasis

The failure of the organs to excrete waste products is very detrimental to the health of a person and could possibly lead to death. Diseases are likewise outcomes of this failure. There are natural bodily processes like Osmoregulation which creates balance thus preventing the occurrence of diseases relating to the excretory organs. There are also man-made treatments to combat the negative effects of the malfunction of the excretory systems like Dialysis for severe kidney diseases.
We shall concentrate on the two excretory organs: the kidneys as a component of the urinary system and the skin as a regulator of temperature. In the course of the discussion of the structures and functions of the urinary system and the skin, the effects of the failure of these systems will be tackled. The terms Osmoregulation and Dialysis will likewise be elaborated and explained.
The urinary system has four major components: the kidneys, the ureters, the urinary bladder and the urethra. The main organs of the urinary system are the kidneys. The kidneys with its functional components called nephrons, form the urine. The process begins during blood circulation. Blood contains Urea, which is produced when protein-rich foods are broken down. Blood through the bloodstream travels through the kidneys and deposits the urea there along with water and other waste matters. This results to the formation of urine.
The ureters are small tubes where urine passes through going to the bladder. Urine is then stored in the urinary bladder. The bladder sends information if there is a need for urination when the bladder is filled up. The contractions of the muscles in the bladder release the urine into a tube called urethra. The urethra is the last passageway which allows the body to release urine or to undergo the process of urination.
The primary function of the urinary system is to get rid of waste products in the body resulting from cellular metabolism. This function preserves the normal composition and volume of body fluids. Aside from maintaining the appropriate amount of water in the body, the urinary system also has other functions. It sustains the normal pH of the blood and helps in managing the proper production of red blood cells by secreting the erythropoietin hormone. By producing the renin enzyme, the urinary system likewise helps in the maintenance of normal blood pressure.
What will happen if the major components of the urinary system fail It will lead to major health problems. Diseases or disorders resulting from the urinary system failure include Kidney Stones which vary in size and may cause little or great pain, and Renal Failure of the kidneys which is a result of the kidneys not being able to properly and completely remove waste products from the blood. In this case, the kidneys are also not able to regulate the chemicals and water in the body. Other disorders are the Urinary Tract Infections which are caused by urinary tract bacteria, Urinary Incontinence, or the inability to control the bladder in releasing urine, and Urinary Retention, or problems in emptying the bladder (Your Urinary System and How It ...Show more

Summary

Homeostasis is the regulation of the physiological processes of organisms to preserve their internal equilibrium as a reaction to changes in the external environment (Homeostastis, Excretion and the Kidneys). Stability is the aim of Homeostasis as it controls internal reactions against external changes by adjusting its processes to maintain balance…
