    Study Notes

    Kidney Structure and Function

    • The kidneys are responsible for filtering blood and producing urine.
    • They are located on the posterior abdominal wall at the level of the 12th rib.
    • The renal fascia is a layer of tissue that surrounds the kidney and anchors it in place.
    • The renal capsule is the outermost layer of the kidney that protects it from injury.
    • The outer region of the kidney is called the renal cortex, and the inner region is called the renal medulla.

    Kidney Functions

    • The kidney regulates blood volume and indirectly controls blood pressure.
    • It plays a role in regulating ion balance and acid-base balance in the blood.
    • The kidney produces erythropoietin, which stimulates the production of erythrocytes when oxygen levels are low.

    Urinary System Functions

    • The urinary system filters waste out of the bloodstream and produces urine from waste.
    • It regulates blood volume and indirectly controls blood pressure.
    • The urinary system does not excrete urine; it is stored in the urinary bladder.

    Urinary Bladder Structure and Function

    • The urinary bladder is a hollow, muscular organ that stores urine.
    • It is located in the pelvis and is partially retroperitoneal.
    • The trigone is an area in the urinary bladder bordered by the ureteral openings and the neck of the bladder.
    • The urethra is the tube that carries urine from the urinary bladder to the outside of the body.

    Urinary Tract Infections and Kidney Stones

    • Urinary tract infections (UTIs) are commonly caused by bacteria entering the urethra.
    • Kidney stones can form anywhere in the urinary tract, from the kidneys to the bladder.

    Kidney Transplant

    • A kidney transplant involves placing a healthy kidney from a living or deceased donor into a person with end-stage kidney disease.
    • In most cases, the existing kidneys are not removed to make space for the transplanted kidney.

    Additional Facts

    • The adrenal gland sits on top of the kidney.
    • The renal pyramid is a triangular section of the kidney that contains the renal columns.
    • The renal papilla is the area where the collecting ducts and nephrons meet.
    • The nephron loop consists of a descending limb and an ascending limb.
    • The collecting duct is part of the nephron and is responsible for merging all major calyces.
    • The vasa recta is a set of capillaries in the medulla where gas and nutrient exchange happens.
    • The ureters are lined with mucosa that stretches to accommodate fluid volume and have smooth muscles for peristalsis to move urine to the urinary bladder.
    • The male urethra is longer than the female urethra.
