JO IB BIO I: unit 6B Kidney & Osmoregulation
ESSENTIAL IDEA: Osmoregulation is controlled by the kidneys ESSENTIAL QUESTIONS: How do animals control the amount of water in their bodies? Why is it common for nitrogenous waste to be excreted by the same organ that regulates water? What are the different parts of the kidney called and what is the function of each part? |
UNDERSTANDINGS / APPLICATIONS / SKILLS / NATURE OF SCIENCE
OSMOREGULATORS and OSMOCONFORMERS
11.3.U1: Animals are either osmoregulators or osmoconformers
11.3.U2: The Malphigian tubule system in insects and the kidney carry out osmoregulation and removal of nitrogenous wastes
11.3.U9: The type of nitrogenous waste in animals is correlates with evolutionary history and habitat
KIDNEY STRUCTURE
11.3.S1: Drawing and labelling a diagram of the human kidney
11.3.S2: Annotations of a diagram of the nephron
KIDNEY FUNCTION
11.3.U3: The composition of blood in the renal artery is different from that in the renal vein
11.3.U4: The ultrastructure of the glomerulus and Bowman’s capsule facilitate ultrafiltration
11.3.U5: The proximal convoluted tubule selectively reabsorbs useful substances by active transport
11.3.U6: The loop Henle maintains hypertonic conditions in the medulla
11.3.U8: ADH controls reabsorption of water in the collecting duct
DEHYDRATION
11.3.A1: Consequences of dehydration and overhydration
11.3.NOS: Curiosity about particular phenomena- investigations were carried out to determine how desert animals prevent water loss in their wastes.
11.3.U7: The length of the loop of Henle is positively correlated with the need for water conservation in animals
KIDNEY DISEASES
11.3.A2: Treatment of kidney failure by hemodialysis or kidney transplant
11.3.A3: Blood cells, glucose, proteins and drugs are detected in urinary tests
