The kidney and liver are organs involved in maintaining homeostasis.

1. The liver is involved in gluconeogenesis (glucose balance).

1.1. Use Google drawing or mind Meister to map out the path of the hormone glucagon from its emergence in the pancreas to the cells of the liver. Draw the receptor of the liver cell and the cell transduction pathway that promotes the building of glucose to be released into the blood stream when blood glucose levels are low.

2. The liver filters toxic substances from the blood.

2.1. Perform the liver catalase lab activity. Use a fresh piece of liver and add it to Hydrogen peroxide to observe the exothermic reaction that converts Hydrogen peroxide to water and Oxygen. This will show how the liver is able to take a potentially harmful substance and convert it into something benign.

3. Kidneys remove metabolic waste from the body.

3.1. Research a disease or condition associated with the kidney that affects the metabolic waste removal process and type a report on the condition.

4. The nephron is the main unit in the kidney that forms urine.

4.1. Perform an osmosis lab to show how water is reabsorbed back into the blood as it passes through the nephron. Water will pass through semipermeable material to dilute an area with high solute concentration.
