Procedure
Part A:
Urinary System

• Use the Figures in the lab manual and the images on these two slides to answer questions in Part A of the Lab Report.

Part A; Image 1 shows a lateral view of a kidney with the inside anatomy of the kidney exposed. The letter A is pointing to the thick outer layer of the kidney. The letter B is pointing to two of the many triangular shaped structures in the inner medulla of the kidney. The letter C is pointing to the solid spaces between the triangles in the inner medulla. The letter D is pointing to the inner part of the kidney containing the renal pyramids and renal columns. The letter E is pointing to the Red blood vessel supplying the kidney with blood. The letter F is pointing to the blue blood vessel that drains blood from the kidney. The letter G is pointing to the cavity in the hilum of the kidney attached to the tube that drains the urine from the kidney. The letter H is pointing to the tube that drains the urine from the kidney.
Image A: part 2 shows the tubular nephron. The letter A is pointing to the squiggly shaped tube closest to the site where the filtrate is first formed. The letter B is pointing to the part the nephron that dips down into the medulla. The letter C is pointing to the squiggly shaped tube farthest from the site where the filtrate is first formed. The letter D is pointing to the ball of capillaries where blood is filtered. The letter E is pointing to the cup shaped structure surrounding the ball of capillaries. where blood is filtered. The letter F is pointing to the part of the nephron carrying the filtrate back up into the cortex. The letter G is pointing to the tube carrying the urine away from the nephron and towards the ureter.

• Place the structures listed below in the correct order to trace the flow of urine from its site of formation (where fluid is first filtered from the blood into the tubules) to outside the body.

Image is a list of words that read: Ascending loop of Henle, Bowman’s capsule, Collecting ducts, Descending loop of Henle, Distal convoluted tubules, loop of Henle, Major calyx, minor calyx, Outside the body, Proximal convoluted tubule, Renal papilla, Renal pelvis, Ureter, Urethra and urinary bladder

• Use Table 12.1 in the Lab Manual to answer the remaining question in part A of Lab 12 Lab Report.

Part B:
Reproductive System

• Use the images on these two slides to answer questions 29-47 in Part B of Lab 12 Lab Report.

Part B; Image 1 shows a lateral view of the male urinary and reproductive systems. The letter A is pointing to an organ that collects and stores urine. The letter B is pointing to the tube that leads from the structure the letter I is point at. The letter C is pointing to the tube that leads from the organ the letter A is point at to outside the body. The letter D is pointing to the external male urogenital organ. The letter E is pointing to the male organ, held outside the body that is the site where sperm are made. The letter F is pointing to an organ the is connected to the vas deferens and is near the urinary bladder. The letter G is pointing to the organ through which the vas deferens enters and meets up with the urethra. The letter H is pointing to the small organ attached to the distal urethra. The letter I is pointing to the site above the testis where sperm mature.
Part B; Image 2 shows a lateral view of the female urinary and reproductive systems. The letter A is pointing to the tube connecting the ovary to the uterus. The letter B is pointing to an organ that collects and stores urine. The letter C is pointing to external female genitalia. The letter D is pointing to the organ where eggs are produced. The letter E is pointing to the thick-walled organ attached to the uterine (fallopian) tube and the vagina. The letter F is pointing to the opening between the uterus and the vagina. The letter G is pointing to the tube between the uterus and outside the body.

• Answer the remaining questions in Part B in Lab 12 Lab Report.
