Topic 11.3: Kidney and Osmoregulation
Essential Idea: All animals excrete nitrogenous waste products and some animals also balance water and solute concentrations.
At SHS, Topic 11.3 is taught in the following class unit(s):
Statements & Objectives:
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.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.U7 The length of the loop of Henle is positively correlated with the need for water conservation in animals.
11.3.U8 ADH controls reabsorption of water in the collecting duct.
1.3.U9 The type of nitrogenous waste in animals is correlates with evolutionary history and habitat.
11.3.A1 Consequences of dehydration and over-hydration.
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.
11.3.S1 Drawing and labeling a diagram of the human kidney.
11.3.S2 Annotations of a diagram of the nephron.
11.3.NOS Curiosity about particular phenomena- investigations were carried out to determine how desert animals prevent water loss in their wastes.
