Dan is a 20-year-old with plaque psoriasis. He reports that his father also had severe plaque psoriasis throughout his life. Dan wants to know what this is, what occurs, and an explanation of two treatments that may assist in making it less noticeable to others who do not understand the disease. What would you tell him?

A combination of nephrotoxic drugs and metformin contributed to Sharon’s rapid decline. Glomerulonephritis is characterized by inflammation of the glomerulus, leading to increased vascular permeability. Describe how glomerulonephritis will impact the process of filtration in the nephron. What is the impact on GFR? Predict blood and urine albumin levels, and discuss how glomerulonephritis will impact fluid and nutrient exchange in systemic capillaries. How does this cause edema in many patients with glomerulonephritis?

Which group of pacemaker cells is responsible for setting the heart rate in a healthy patient? Write a flow diagram (eg: structure A --> structure B --> structure C, etc.) to describe the path that an action potential would take as it makes its way through the electrical conduction system of the heart, being sure to name all structures. What structure enables action potentials to directly spread between neighbouring cardiomyocytes? Be specific.
