2. Trace the flow of blood through the kidney and describe how blood is filtered in the kidney nephron.
3. Provide symptoms of kidney failure and describe the normal versus abnormal urine composition. (normal range of pH, osmolarity, and volume)
4. List some of the solutes filtered, secreted, and reabsorbed in different parts of the nephron.
5. Describe the role of a portal system in the kidney.
6. Explain how urine osmolarity is hormonally regulated and describe the regulation of major ions by the kidney.
7. Summarize the role of the kidneys in maintaining acid-base balance.
8. Compare and contrast blood plasma, glomerular filtrate, and urine characteristics.
9. Compare and contrast male and female urethras.
10. Describe the micturition reflex.
11. Describe the external structure of the kidney, including its location, support structures, and covering.
Identify the major internal divisions and structures of the kidney, identify the major blood vessels associated with the kidney.
12.Name structures found in the cortex and medulla, describe the physiological characteristics of these areas and 13.compare and contrast the cortical and juxtamedullary nephrons.

17.Describe the histology of the proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting ducts
18.Describe glomerular filtration rate (GFR), state the average value of GFR, and explain how clearance rate can be used to measure GFR, predict specific factors that will increase or decrease GFR
19.State the percent of the filtrate that is normally reabsorbed and explain why the process of reabsorption is so important
20.List common symptoms of kidney failure, and discuss the aging kidney and its function.
21.Describe how each of the following functions in the extrinsic control of GFR: renin-angiotensin mechanism, natriuretic peptides, and sympathetic adrenergic activity
22.Describe how each of the following works to regulate reabsorption and secretion, so as to affect urine volume and composition: renin-angiotensin system, aldosterone, antidiuretic hormone, and natriuretic peptides
23.Name and define the roles of other hormones that regulate kidney control, what effect do diuretics have on fluid retention and loss?
24.Explain why the differential permeability or impermeability of specific sections of the nephron tubules is necessary for urine formation
25.Describe the role of the kidneys in vitamin D activation, and the role of the kidneys in regulating erythropoiesis
