BioLab3 Urogenital System Lab Report Name, date, course and section required for password: The lab report is unique each semester and checks have been put into place to ensure students are doing their own work. Copying from other students or from outside sources will result in a zero on the accompanying lab quiz. Urinary System Excretory systems include the Respiratory with CO2 release, skin via sweat, digestive excretes feces, and the urinary system filters the blood and excretes urine. The parts of this system include: Ex 1, read through the anatomy of the Urinary system and write the functions of each structure in Step 1. Name of structure Function A Renal artery A Renal vein B Kidneys C Ureters D Bladder E Urethra II. Kidney Anatomy Read about the anatomy of the kidney and complete Ex 2, Step 4. Fill out the table of the 5 structures from the model of the kidney (not the pig kidney). Name of Structure Function A Renal capsule B Renal hilum C Renal pyramid D Renal medulla E Renal cortex Kidney Microstructure A. Nephron Examine the kidney microstructures. Ex 3 Nephron structure, fill out the table with the description of each structure. Nephron structure Location Description A Bowman’s capsule cortex B Proximal convoluted tubule cortex C Descending loop of Henle medulla D Ascending Loop of Henle medulla E Distal convoluted tubule cortex F Collecting duct medulla Draw a single nephron, the functional unit of the kidney. Label the Renal Corpuscle (Bowman’s Capsule + glomerulus), Renal tubule (proximal convoluted tubule + Loop of Henle + distal convoluted tubule) and Collecting duct. This is the path of the urine. Include the Renal circulation structures: the path of the blood is the renal artery, afferent arteriole, glomerular capillaries, efferent arteriole, peritubular capillary bed, and renal vein. Sign, date, produce an image of your drawing and include in your lab report. Urine Formation Read sections A, B, C of urine formation then fill out the following table. Process Location in nephron What is in the filtrate, in the tubules as part of urine Filtration Reabsorption Secretion After the kidney what is the path of urine out of the body? In Ex 4, follow steps 1 and 2 and determine what will remain in the urine. Substance Urine Substance Urine Water Glucose Proteins Urea Chloride Cl- Potassium K Sodium Na+ Uric Acid Bicarbonate Creatinine Urinalysis A. Appearance of Test Specimen The color of urine is a first indicator to consider. Fill out the table comparing different colors of urine for possible causes. Color of urine Possible causes Light straw to amber, clear Pigment urochrome breakdown of hemoglobin normal color Milky, cloudy Reddish, amber Brownish yellow to green Red to smoky brown In Ex 5, examine urine appearance. Observe Steps 1, 2, 3. How do they match to the above chart. B. Multistix Strip Testing What would be the normal readings for these variables? H+ ion Concentration- Protein Detection- Glucose detection- Hemoglobin Detection- Specific Gravity- In Ex 6, go through Steps 1-3 and summarize the results of the urinalysis for the three samples. C. Abnormal Urine Constituents A man who runs marathons and is on a high protein, low carb diet might have an abnormal urine reading of: VI. Male Reproductive System Male Reproductive System Anatomy Read the information of the male reproductive tract. Name the function for each part of the path of the sperm and accessory glands: Pathway of Sperm in male system Function Testes (external to body) Scrotum (external to body) Epididymis Vas deferens Ejaculatory duct Urethra Penis (external to body Seminal vesicles Prostate gland Bulbourethral glands Sperm Structure In Ex 8, view diagram of a sperm cell and write contents of each part of cell: A. Tail B. Midpiece C. Acrosome D. Head of sperm VII. Female Reproductive System Female Reproductive System Anatomy In Ex 9, review the structures of the female reproductive tract and identify their function: Reproductive structure Function A Fallopian tubes (Oviduct) B Fimbriae C Ovary D Uterus E Cervix F Vagina Ovum Development How many oocytes reach maturity in the life of a female? Sperm cells must penetrate two layers that surround an oocyte. Name them. Meiosis II completes when the egg is: Summary Questions . Follow the path of the urine through the parts of the nephron and then out of the body. Name two substances that should not be found in normal urine. Compare the difference between male and female urethra. Follow the path of sperm from the testes to the egg. What structures in the male and the female are involved? Describe the process of fertilization, include where it happens, the role of the acrosome of the sperm and the chromosome number change. © 2022 Access Learning Systems FA22 6
