CHAPTER 10: CARE OF THE PATIENT WITH A URINARY DISORDER

URINARY SYSTEM STRUCTURES AND FUNCTION

  • The urinary system consists of:

    • Kidneys

    • Ureters

    • Bladder

    • Urethra

    • Nephron

KIDNEYS

  • The human body typically has two kidneys.

  • Primary Functions of Kidneys:

    • Excretion of Waste: The kidneys filter the blood to remove waste products.

    • Regulation of Water and Electrolytes: They assist in maintaining the body’s fluid balance and electrolyte levels.

    • Secretion of Erythropoietin: This is crucial for the production of red blood cells.

    • Acid-Base Balance: The kidneys help to regulate the pH of the blood.

URETERS

  • Their function is to transport urine from the kidneys to the bladder.

BLADDER

  • The bladder's role is to collect and store urine.

URETHRA

  • The urethra is responsible for transporting urine from the bladder to outside the body.

NEPHRON

  • Each kidney contains over 1 million nephrons.

  • Functional Unit of the Kidney: The nephron is essential for filtering blood and processing urine.

  • Key Focus Areas: Understanding urinary elimination as a critical aspect of overall health and management in urinary disorders.

URINARY SYSTEM STRUCTURES AND FUNCTION

  • The urinary system consists of:

    • Kidneys: Bean-shaped organs responsible for filtering blood and producing urine.

    • Ureters: Muscular tubes that transport urine from the kidneys to the bladder through peristaltic movements.

    • Bladder: A muscular sac that collects and stores urine until voluntary elimination occurs.

    • Urethra: A tubular structure through which urine exits the bladder, connecting it to the exterior of the body.

    • Nephron: The functional unit of the kidney, crucial for filtering and excreting waste products.

KIDNEYS

  • The human body typically has two kidneys, each located on either side of the spine, behind the peritoneum. They play a vital role in maintaining homeostasis.

  • Primary Functions of Kidneys:

    • Excretion of Waste: The kidneys filter out toxins and waste products from the bloodstream, including urea, creatinine, and excess electrolytes, to prevent toxicity.

    • Regulation of Water and Electrolytes: They help regulate the body's fluid levels and electrolyte concentrations, such as sodium, potassium, and calcium, which are essential for normal function and health.

    • Secretion of Erythropoietin: This hormone stimulates the production of red blood cells in response to low oxygen levels in the blood.

    • Acid-Base Balance: The kidneys play a critical role in maintaining the pH level of blood by reabsorbing bicarbonate from urine and secreting hydrogen ions.

URETERS

  • The ureters are muscular passages that transport urine from the kidneys to the bladder. They employ rhythmic contractions (peristalsis) to move urine along, countering the force of gravity.

BLADDER

  • The bladder's role is to collect and store urine. Its muscular wall allows for expansion as it fills and contraction during urination, relying on detrusor muscle contractions.

URETHRA

  • The urethra is responsible for transporting urine from the bladder to outside the body. In males, it also serves as a passageway for semen during ejaculation.

NEPHRON

  • Each kidney contains over 1 million nephrons, making it critical for urinary function.

  • Functional Unit of the Kidney: The nephron filters blood, and as it processes urine, it plays roles in absorption and secretion.

  • Three Major Functions of Nephrons:

    • Controlling Body Fluid Levels: Nephrons regulate the volume and concentration of urine by selectively removing or retaining water.

    • Regulation of pH: By excreting hydrogen ions and reabsorbing bicarbonate, nephron activity affects the blood’s acidity/alkalinity.

    • Removal of Toxic Waste: They filter out waste products like urea and creatinine, keeping blood clean and balanced.

THREE PHASES OF URINE FORMATION

  • Urine formation consists of three primary phases:

    • Filtration: Occurs in the glomerulus, where blood plasma is filtered into the Bowman’s capsule.

    • Reabsorption: Essential nutrients, water, and electrolytes are reabsorbed back into the bloodstream from the renal tubules.

    • Secretion: Additional waste products are secreted into the filtrate, preparing it for excretion.

HORMONES THAT AFFECT NEPHRON FUNCTION

  • Antidiuretic Hormone (ADH): This hormone enhances water reabsorption in the kidneys, reducing urine output and concentrating the urine. It plays a vital role in maintaining fluid balance and blood pressure regulation.
