1 The Urinary System By: Paige Berglund & Danielle White

2 Unit Learning Target: Investigate the structures of the urinary system that help maintain homeostasis by balancing concentrations of water, electrolytes, and hydrogen ions in the body

3 Learning Target: List the functions of the urinary system (knowledge)

4 The urinary system 1.) Removes certain salts and nitrogenous wastes (wastes made by cellular processes) 2.) Maintains normal concentration of water and electrolytes (controlled through output in urine) 3.) Regulates the pH and volume of our body fluids Word Bank: Processes, pH, electrolytes, output

5 Learning Target: Identify the structures of the urinary system and state the function of each structure (knowledge)

6 Label a diagram of the urinary system
1 2 3 4 Word Bank: Bladder, Urethra, Ureters, Kidneys

7 Match the 4 main structures of the urinary system with their function
Kidneys Ureters Bladder Urethra Transports urine to the bladder Receives urine from the ureters Carries urine from the bladder to an orifice (opening) Helps maintain homeostasis by regulating the composition, volume, and pH of extracellular fluid

8 Identify the structures of the kidney
Word Bank: Renal Pelvis, Renal Medulla, Renal Capsule, Renal Cortex 1 Renal Medulla Renal Capsule 2 Renal Cortex 3 Renal Pelvis 4

9 Match the structure in the kidneys with the function
Renal Cortex Renal Medulla Renal Capsule Renal Papilla Renal Pelvis Urine drains into minor calyx Funnels urine to ureter Covering, and maintains pressure Site of absorption Site of filtration

10 True or False: The kidneys are located on the anterior walls of the abdominal wall?
False: The kidneys are actually located on the posterior abdominal wall

11 What kind of tissue holds the kidneys in place?
A. Kleenex B. Adipose C. Dense Connective D. B and C

12 What kind of tissue protects the kidneys?
A. Dense Connective B. Adipose C. Smooth D. A and B

13 Functions of the kidneys include
A. Maintain pH levels and H+ ions B. Regulate composition of electrolytes C. Filters wastes D. Secrete hormones and enzymes E. All of the above

14 Secretion of hormones and enzymes associated with the kidneys
Erythropoietin Renin Calcitriol An enzyme that regulates blood pressure A hormone that helps maintain calcium for bones A hormone that stimulates bone marrow to make red blood cells

15 Learning Target: Using diagrams, explain the role of the nephron in urine formation. (reasoning)

16 Identify nephron structures and know the function of each structure
3 2 4 1 5 6 7 Afferent arterioles, efferent arterioles, glomerulus, glomerular capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule

17 What happens to the unfiltered blood once it enters the renal corpuscle?
It sits there It gets filtered Leaves directly out the urethra Reenters the blood stream

18 True or False During tubular reabsorption the blood reabsorbs needed substances from the proximal convoluted tubule. TRUE!

19 True or False During Tubular reabsorption additional items are added to the forming urine.

20 How does urine leave the nephron?
Collecting duct Peritubular capillary Descending limb Glomerular capsule

21 Learning Target: What disorders are associated with the kidney and how are they treated? (knowledge)

22 Diabetic Kidney Disease
If glucose stays in the blood instead of breaking down, it can act like a poison, damaging the (nephrons / renal capsule).

23 High Blood Pressure Can damage the small blood vessels in the (liver / kidneys) so they cant filter wastes.

24 Glomerular Dieseases This attacks the tiny blood vessels, ( glomerulus / tubules ) within the kidney.

25 Polycystic kidney disease
Is a genetic disorder in which many ( cysts / ulcers ) grow in the kidneys.

26 TYLER QUINN!!! True or False: Dialysis is the process by which toxic compounds from the blood are removed? TRUUUUUUUUUE

27 Kidney Dialysis Summarized FUN FACT
A dialysis machine is used to remove toxic waste from the blood of a patient who has chronic kidney failure. A healthy kidney is involved in removing waste products from the blood. If the kidney ceases to function adequately the toxic waste in the blood will accumulate which can rapidly cause death.

28 Learning Target: Describe a normal urine sample (knowledge)

29 A normal urine sample would include:
A pH of around ( / 2.1 – 5) A volume of (0.6 – 2.5 / 6.0 – 6.5) L/day A color of (dark green / pale yellow or amber) A clarity of (transparent or clear / cloudy)

30 Given the results of a urine test, determine what condition the patient may have (skill)

Patient 2 is 19 year old female named Laverne. Laverne has been complaining of constant discomfort while urinating. She also has complained about a bad odor every time she goes. When given a urine test the results showed Yeast present Darker color And a bad odor What can you diagnose Laverne with based on the results of the test? YEAST INFECTION

32 Learning Target: Evaluate a patients test results for water, electrolytes, and pH balance. (skill)

33 Why is the balance of water, electrolytes, and pH important?
Balance of water is important because Water only leaves the body Water is continuously entering the body To maintain homeostasis water is continuously entering and leaving the body

34 What body system supports the urinary system in water, electrolytes, and pH importance?
Digestive System Urinary System Respitory System Circulatory System

35 Routes of water balance and regulation
When too much sweating or salt is present water content of blood is (low/high) Then brain then produces more (ADH/Enzymes) (Low/High) volumes of water are reabsorbed by the kidney Urine out put is (high/low)

36 Routes of water balance and regulation
When too much water is present water content in blood is (low/high) The brain then produces (more/less) ADH (Low/high) volumes of water is reabsorbed by the kidneys Urine out put is (low/high)

37 Water intake is regulated by ( thirst, feces)
Water intake is regulated by ( thirst, feces). Water output is regulated by ( urine production, food)

38 True or False The abnormal accumulation of water in the body which results in swelling is called edema. TRUE

39 List routes by which electrolytes enter and leave the body
Electrolytes enter the body through A. food B. beverages C. A and B Electrolytes leave the body through A. sweat, feces, skin/lungs, urine B. sweat, water, urine C. sweat, feces, respiration

40 What happens when pH is not balanced?
A. Overweight, underweight, fatigue, acne B. Sores on body, odor, nausea C. Frequent urination, diarrhea
