  • What are the two main parts of the nephron?
    The two main parts of the nephron are the renal corpuscle and the renal tubule.
  • What is the functional unit of the kidney?
    Nephron
  • Which of these is the functional unit of a kidney?
    The functional unit of a kidney is the nephron.
  • About how many nephrons are in a kidney?
    Each kidney contains about 1 to 2 million nephrons.
  • What is the correct sequence for parts of the renal tubule?
    The correct sequence is proximal tubule, nephron loop, distal tubule.
  • What components make up the renal tubule?
    Proximal tubule, nephron loop, distal tubule
  • Which choice describes the countercurrent mechanism of the nephron loop?
    The countercurrent mechanism in the nephron loop helps concentrate urine by creating a gradient in the medulla.
  • Which part of the nephron is influenced by hormones to absorb sodium and water?
    The distal tubule and collecting duct are influenced by hormones to absorb sodium and water.
  • From how many nephrons does one collecting duct receive tubular fluid?
    Multiple nephrons
  • Which is the term for the functional units of the kidneys?
    The term for the functional units of the kidneys is nephrons.
  • What is the correct order of components of a nephron starting from the glomerulus?
    Glomerulus, proximal tubule, nephron loop, distal tubule
  • Which structure is not associated with the renal corpuscle?
    Proximal tubule
  • From which part of the nephron does the collecting duct receive fluid?
    Distal tubule
  • What is the order in which blood flows through the nephron?
    Glomerulus, proximal tubule, nephron loop, distal tubule
  • A nephron consists of what two parts?
    A nephron consists of the renal corpuscle and the renal tubule.
  • Where is the majority of the nephron loops located?
    Renal medulla
  • The renal corpuscle includes what two structures?
    The renal corpuscle includes the glomerulus and the glomerular capsule.
  • Which of the choices below is a function of the nephron loop?
    The nephron loop functions in concentrating urine by creating a gradient in the medulla.
  • How many nephrons does each kidney have?
    Each kidney has about 1 to 2 million nephrons.
  • Which process in the nephron is least selective?
    Filtration in the glomerulus is the least selective process in the nephron.
  • Which are the two major components of a nephron?
    The two major components of a nephron are the renal corpuscle and the renal tubule.
  • What are the two main parts of a nephron?
    The two main parts of a nephron are the renal corpuscle and the renal tubule.
  • Aquaporins allow what to pass through the descending limb of loop of Henle?
    Aquaporins allow water to pass through the descending limb of the loop of Henle.
  • A nephron consists of what structures?
    A nephron consists of the renal corpuscle and the renal tubule.
  • Which part of the nephron performs the majority of water reabsorption?
    The proximal tubule performs the majority of water reabsorption.
  • What happens when the concentration of Na+ decreases in the ascending limb of the nephron?
    When the concentration of Na+ decreases in the ascending limb, less sodium is reabsorbed, affecting the osmotic gradient.
  • Which structures make up the renal corpuscle?
    The renal corpuscle is made up of the glomerulus and the glomerular capsule.
  • What are the two major components of a nephron?
    The two major components of a nephron are the renal corpuscle and the renal tubule.
  • What does the countercurrent mechanism accomplish in the nephron loop?
    The countercurrent mechanism in the nephron loop helps concentrate urine by creating a gradient in the medulla.
  • Which structure in the nephron collects urine from the distal convoluted tubule?
    The collecting duct collects urine from the distal convoluted tubule.
  • Most water is reabsorbed from the filtrate by which region of the nephron?
    Most water is reabsorbed by the proximal tubule.
  • Water is absorbed from what part of the loop of the nephron?
    Water is absorbed from the descending limb of the nephron loop.
  • The nephron is broken down into which two major portions?
    The nephron is broken down into the renal corpuscle and the renal tubule.
  • What effect does antidiuretic hormone (ADH) have on the nephron?
    ADH increases water reabsorption in the distal tubule and collecting duct.
  • What percentage of all nephrons are cortical nephrons?
    They make up 80% of all nephrons
  • What is the correct path of filtrate through a nephron of the kidney as it is processed into urine?
    The correct path is glomerulus, proximal tubule, nephron loop, distal tubule, collecting duct.
  • What structure in the kidney acts as the countercurrent multiplier?
    Nephron loop
  • What is the role of the collecting ducts?
    The collecting ducts further modify filtrate and collect it from multiple nephrons, eventually leading to urine formation.
  • Where in the nephron does most solute reabsorption occur?
    Most solute reabsorption occurs in the proximal tubule.
