Lab Urinary

Objectives:

  • Understand the organization of the glomerulus and the cells present within it.
  • Distinguish the key microscopic components of the renal cortex and medulla
  • Identify the structural components of the nephron
  • Describe the structure of the surface across which filtration occurs
  • Identify and distinguish the proximal tubule, distal tubule, and collecting duct
  • Identify the component cells of the juxtaglomerular apparatus
  • Describe the filtration barrier between blood and urine in the glomerulus
  • Name the divisions of the nephron, and specify their locations (pars convoluta or medullary ray of cortex, or medulla).
  • Relate the histological specializations found in specific divisions of the nephron to the functions of that division.
  • Describe the blood supply of the kidney.

You will study the kidney, ureter and bladder. Your main goal in the kidney will be to understand how blood vessels and nephrons are organized in the kidney cortex and medulla, and how this arrangement is related to the production of urine. The nephron consists of a renal corpuscle (the glomerulus and Bowman’s capsule), a proximal tubule (with convoluted and straight portions), a thin segment, and a distal tubule (with straight and convoluted portions). The nephron empties into a collecting duct. (Adapted from U MIchigan Labs)
