Urinary System & Alcohol Consumption

Urinary System & Alcohol Consumption

Introduction

Our health and internal body mechanism is dependent on the urination process, which is the elimination of toxic wastes ad excess water from the body in the form of urine. The process is called urination and the waste product is the urine. The process of excretion is important to maintain the internal homeostasis of the body as well as it plays an essential role in clearing the body from different sorts of waste products resulted due to many chemical reactions taking place in the body (NKUDIC, 2012).

Kidneys are the main organs which functions to remove the waste products from the body in the form of urine. Urine is a composition of water, salts, certain types of electrolytes and the waste generated in the body, and all of them together in the form of urine are expelled out of the blood. The purification of the blood takes place entirely in the kidneys, and the resulting waste also collected due to the metabolism of food we eat enters into the blood, which is than expelled out by the kidney purification process. For the formation of urine and blood purification, the blood passes through the kidneys and the process of filtration takes place. The whole process is divided into three stages; filtration, re-absorption, and secretion (NKUDIC, 2012).

Filtration

The process of urine formation begins with filtration which takes place in the renal corpuscles. As blood passes through the glomeruli, much of the fluid portion, which comprises of water, required chemicals and liquefied waste materials flushes the blood through the membranes where it is separated and after that streams into the Bowman's capsule. This process is called glomerular filtration. The fluid which comprises of water, salt, glucose, chemicals and electrolytes which are water soluble filters out of the blood, and this is collectively called as glomerular filtrate. In addition to this glomerular filtrate also consist of the waste called urea. Since ammonia cannot be discharged from the body it is converted into the less risky byproduct called urea and then separated out of the blood. Urea is excreted into the urine in large amounts as it is one of the toxic waste which needs to be removed out from the body timely. The sum rate of glomerular filtration for the entire body including both the kidney is 125ml per minute (Mark, 2004).

Re-absorption

Re-absorption is the backward movement of substances ...
