By Jonas Wilson‚ Ing. Med. Causes of Ureteric Calculi Ureterolithiasis or ureteric calculi are stones that are present in the ureters‚ which are the muscular tubes that connect the kidneys to the urinary bladder. These tubes are physiologically constricted at 3 points along their lengths‚ namely at the ureteropelvic junction‚ entry into the pelvis as they cross the bifurcation of the common iliac artery and the ureterovesical junction. As a consequence‚ these points are the commonest sites where

of urine. Urine is a liquid produced by the kidneys‚ collected in the bladder and excreted through the urethra. Urine is used to extract excess minerals or vitamins as well as blood corpuscles from the body. The Urinary organs include the kidneys‚ ureters‚ bladder‚ and urethra. The Urinary system works with the other systems of the body to help maintain homeostasis. The kidneys are the main organs of homeostasis because they maintain the acid base balance and the water salt balance of the blood.

“The Urinary System” The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The organs included in the urinary system are the kidneys‚ ureters‚ bladder‚ and urethra. The kidneys are two bean-shaped‚ reddish brown organs about the size of your fist. The renal capsule‚ a tough capsule of fibrous connective tissue‚ covers the kidneys. The ribcage protects the kidneys which are located in the back just above the

Chapter 17 - Urinary System 17.1 Introduction (Fig. 17.1) A. The urinary system consists of two kidneys that filter the blood‚ two ureters‚ a urinary bladder‚ and a urethra to convey waste substances to the outside. 17.2 Kidneys (Fig. 17.2) A. The kidney is a reddish brown‚ bean-shaped organ 12 centimeters long; it is enclosed in a tough‚ fibrous capsule. B. Location of the Kidneys 1. The kidneys are positioned retroperitoneally on either side of the vertebral column between the twelfth

* 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.

urolithiasis is a complex process which began with the formation of hard‚ crystalline mineral material that grew and got retained within the urinary tract. Urolithiasis can be form within and obstruct the renal calices or the ureter. Obstructions plus periodic peristalsis of the ureter result in spasms of severe pain‚ radiating to flack and groin area.

1. Anatomy- study of the structure and shape of the body and its parts. Physiology- study of how the body and its parts work or function. The relationship between anatomy and physiology is that anatomy has to do with the structures and names of the body‚ while physiology has to do with the function and how the structure works. An example of their correspondence is the cardiovascular system‚ consisting of the heart and blood vessels (anatomy) and how the heart pumps oxygen‚ nutrients‚ and wastes
