Biology 12 Competency Measure -

Demonstrate the Relationship between Structure and Function using the Sheep or Pig Kidney Dissection

Allied Health Program: Program Outcome 1 - Demonstrate knowledge of basic concepts of anatomy and physiology

Directions: Using models of the kidney, a dissected sheep or pig kidney, slides of the microscopic anatomy of the kidney, and an understanding of kidney physiology from reading and lectures, the student will demonstrate an ability to discern the relationship between structure and function in the human kidney.

This assessment is graded according to the following criteria. Passing grade is 70%.

ASSESSMENT CRITERION

POINT VALUE

STUDENT NAMES and SCORES

The student will identify five (5) parts of the kidney from the 20 listed below

Ureters Renal Hilus

Renal capsule Afferent arteriole

Renal cortex Efferent arteriole

Renal medulla Renal corpuscle

Renal pyramids Glomerulus

Renal pelvis Proximal tubule

Major calyx Distal tubule

Minor calyx Loop of Henle

Renal artery Peritubular capillary bed

Renal vein Collecting ducts

(6 points each)

Maximum score = 30 points

_________________

In essay format, the student will answer any 2 of the following 5 questions and integrate an understanding between structure and function in their response.

· Explain the significance of the difference in diameter of the afferent and efferent arterioles and to relate the difference to the process of filtration.

· Explain the significance of the single cell structure and microvilli found in the proximal convoluted tubule.

· Explain the significance of the proximity between the Loop of Henle and the collecting ducts with regard to the kidney’s ability to produce concentrated urine.

· Describe the difference between tubular secretion and tubular reabsorption.

· Explain why the kidney is especially susceptible to damage related to untreated high blood pressure.

(20 points each)
