The urinary system is an important body system to eliminate waste from the body.The urinary system is made up of:1. Kidneys2. Ureters3. Bladder 4. UrethraThe normal urinary system has two main functions:1. Filter the blood so that its waste material is discharged through the outside though the kidneys and its distributing system of ureters, bladder and urethra.2. Maintain water balance, acid base equilibrium of body fluids and proper amount of salts in the body.The Kidneys:The kidneys are two bean-shaped organs, each about the size of a fist.They are located near the middle of the back, just below the rib cage, one on each side of the spine.Every day, the two kidneys process about 180 liters of blood to produce about 1 5 liter of urine, composed of wastes and extra water.The urine flows from the kidneys to the bladder through tubes called ureters.The bladder stores urine until releasing it through urination.When the bladder empties, urine flows out of the body through a tube called the urethra at the bottom of the bladder.The kidneys in the adult human measure 4.5inches long, 2-3inches wide and a little over 1inch thick.They are slightly longer in men than in women.They are located on each side of the vertebral column just behind the peritoneum of the abdominal wall extending from the waistline upwards to the level of the 12th rib.The right kidney is pressed down by the liver and is lower than the left.The kidneys resemble a pair of beans turned on the flat side are embedded in fat which helps to support them.In the middle of the each kidney surface is a concave indentation the hilum through which the blood vessels, lymph vessels and nerves enter and from which the ureter emerges.The capsule of the kidney is made up of thick tough white fibers.Connective sheets of tissues help to keep the kidneys in position.Since the kidneys touch the diaphragm they move with it when air is drawn through the lungs.Blood supplyThe kidneys receive blood from the renal arteries, left and right, which branch directly from the abdominal aorta.Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output.Each renal artery branches into segmental arteries, dividing further into interlobar arteries which penetrate the renal capsule and extend through the renal columns between the renal pyramids.The interlobar arteries then supply blood to the arcuate arteries that run through the boundary of the cortex and the medulla.Each arcuate artery supplies several interlobular arteries that feed into the afferent arterioles that supply the glomeruli.The interstitium is the functional space in the kidney beneath the individual filters (glomeruli) which are rich in blood vessels.The interstitium absorbs fluid recovered from urine.Various conditions can lead to scarring and congestion of this area which can cause kidney dysfunction and failure.After filtration occurs the blood moves through a small network of venules that converge into interlobular veins.As with the arteriole distribution the veins follow the same pattern, the interlobular provide blood to the arcuate veins then back to the interlobar veins which come to form the renal vein exiting the kidney for transfusion into the blood.The renal artery enters into the kidney at the level of first lumbar vertebra just below the superior mesenteric artery.As it enters the kidney it divides into branches:1. First the segmental artery, which divides into 2 or 3 lobar arteries, then further divides into interlobar arteries which further divide into the arcuate artery which leads into the interlobular artery which form afferent arterioles.The afferent arterioles form the glomerulus (network of capillaries closed in Bowman's capsule).TABLE OF CONTENTChapter 1 The KidneysChapter 2 Kidney FunctionChapter 3 The NephronChapter 4 Importance of KidneysChapter 5 The Urinary system and Diseases
