Topic 11.3:  Kidney and Osmoregulation

Understandings:
  • Animals are either osmoregulators or osmoconformers.
  • The Malphigian tubule system in insects and the kidney carry out osmoregulation and removal of nitrogenous wastes.
  • The composition of blood in the renal artery is different from that in the renal vein.
  • The ultrastructure of the glomerulus and Bowman’s capsule facilitate ultrafiltration.
  • The proximal convoluted tubule selectively reabsorbs useful substances by active transport.
  • The loop Henle maintains hypertonic conditions in the medulla.
  • The length of the loop of Henle is positively correlated with the need for water conservation in animals.
  • ADH controls reabsorption of water in the collecting duct.
  • The type of nitrogenous waste in animals is correlates with evolutionary history and habitat.
Applications:
  • Consequences of dehydration and over-hydration.
  • Treatment of kidney failure by hemodialysis or kidney transplant.
  • Blood cells, glucose, proteins and drugs are detected in urinary tests.
Skills
  • Drawing and labeling a diagram of the human kidney.
  • Annotations of a diagram of the nephron.
Nature of Science
  • Curiosity about particular phenomena- investigations were carried out to determine how desert animals prevent water loss in their wastes.
