Blood Supply of the Kidneys definitions
1/15
  • Renal Artery

    The main vessel supplying blood to the kidneys, carrying about one fourth of total cardiac output.
  • Renal Vein

    The vessel through which filtered blood exits the kidneys.
  • Cortical Nephron

    A type of nephron located primarily in the renal cortex, involved in blood filtration.
  • Juxtamedullary Nephron

    A nephron type with loops extending deep into the renal medulla, aiding in concentrated urine formation.
  • Collecting Duct

    A structure in the kidney where urine is collected from nephrons before moving to the renal pelvis.
  • Afferent Arteriole

    The small artery that carries blood to the glomerulus for filtration.
  • Efferent Arteriole

    The vessel that drains blood from the glomerulus, leading to peritubular capillaries.
  • Glomerulus

    A network of capillaries within the renal corpuscle where blood filtration begins.
  • Peritubular Capillaries

    Capillaries surrounding renal tubules, involved in reabsorbing water and solutes.
  • Vasa Recta

    Capillary networks parallel to nephron loops in juxtamedullary nephrons, aiding in urine concentration.
  • Renal Cortex

    The outer region of the kidney containing cortical nephrons and parts of juxtamedullary nephrons.
  • Renal Medulla

    The inner region of the kidney, containing nephron loops and vasa recta.
  • Renal Corpuscle

    The initial blood-filtering component of a nephron, consisting of the glomerulus and Bowman's capsule.
  • Nephron Loop

    A U-shaped segment of the nephron that extends into the renal medulla, crucial for urine concentration.
  • Proximal Tubule

    The segment of the nephron where most reabsorption of water, ions, and nutrients occurs.
