Homeostasis is defined as the adjustments a body makes to maintain an environment conducive to life. All of the organ systems in the human body must maintain a steady internal environment for the body to function properly. The factors that need to be controlled are water and salt content‚ PH balance‚ oxygen‚ sugar‚ protein‚ body temperature‚ and blood and glucose concentration. The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

* Trivia: Other terms used to refer to the "Urinary System" include the "Renal System" and the "Genito-urinary System" * Important Functions of Urinary System *Besides removing waste from bloodstream‚ the urinary system preforms several other functions as well. They are as follows: * Storage of Urine: Urine is producing all the time‚ but it would be inconvenient if we were constantly excreting urine. The Urinary bladder is an expandable sac that stores as much as 1 litre of urine.

The urinary system a very valid and important system though underrated. And why is that‚ we see ads on the TV for dialysis centers‚ kidney stones‚ UTI infections‚ and bladder control issues‚ not to mention bladder cancer. The purpose for this paper is to explain the urinary system. The urinary system is made of two kidneys‚ two ureters‚ two sphincters muscles‚ the bladder and the urethra. The kidneys filter metabolic waste and chemicals from blood to the urine. They do this by filtering units called

Name different parts of a nephron. Write absorption and secretion of different parts of a nephron. Nephron: It is the functional part of the kidney‚ encharged of filtration of blood and eliminates the nitrogenous waste of our bodies. The nephron consists of: functional units; two parts: renal corpuscle

-Contributions to metabolism: The kidneys help synthesize the hormone calcitriol. 2. Kidneys: the kidneys filter out wastes from the blood these wastes are then liquified into urine. Ureters: The ureters funnel the urine into the Urinary Bladder. Urinary Bladder: the urinary bladder stores the urine until muscle contraction forces the urine out. Urethra: the urethra is where the urine is forced out of the body. 3. 4. Renal Capsule: a smooth‚ transparent‚ fibrous

Homeostasis is important in maintaining a healthy functioning of the body. Enzymes within the body are vitally responsible for speeding up chemical reactions and are often referred to as catalysts. In order to work at their optimum‚ enzymes need a specific constant temperature within the internal environment of the body to function correctly and reduce denaturing. A healthy human body should have a body temperature of 37∙C‚ the optimum temperature for enzymes to function. Therefore‚ the temperature

Function The urinary system helps maintain homeostasis by regulating water balance and by removing harmful substances from the blood. The blood is filtered by two kidneys‚ which produce urine‚ a fluid containing toxic substances and waste products. From each kidney‚ the urine flows through a tube‚ the ureter‚ to the urinary bladder‚ where it is stored until it is expelled from the body through another tube‚ the urethra. The kidneys are surrounded by three layers of tissue: The renal fascia
