1. The Excretory System
Chris Schneider

2. The main function Excretory system
Removes metabolic and liquid toxic waste in the form of one of three liquids, Urea, Uric acid, and Ammonia. In humans, it is urea.
It also takes part in osmoregulation, providing homeostasis for the body.

3. Parts of the Excretory System Kidney
Primary function is the removal of cell waste from the blood stream.
Maintain volume of extracellular fluid
Maintain ionic balance
Maintain pH and osmotic concentration
Excrete toxic metabolic by-products such as urea, ammonia, and uric acid

5. Parts of the Excretory System Ureters
Tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder

6. Parts of the Excretory System Bladder
the organ that collects urine excreted by the kidneys before disposal by urination
Hollow, muscular organ
Urine enters the bladder through the ureters and exits through the urethra

7. Parts of the Excretory Systems Urethra
A tube that connects the urinary bladder to the genitals for the removal of fluids from the body
In males, the urethra also carries semen

8. Types of nitrogenous waste of the excretory system
Ammonia
Most toxic
Used by fish and other aquatic life
Urea
Medium Toxicity
Used by mammals and some fish
Uric Acid
Least toxic
Used by birds and reptiles

9. Nephron in the Excretory System, Filtration
The first stage in clearing the blood is filtration, the passage of a liquid through a filter to remove impurities. Filtration occurs in the glomeruli

10. Nephron in the Excretory System, Reabsorption
During reabsorption, needed substances in the filtrate travel back into the bloodstream. Reabsorption occurs in the renal tubules. There, glucose and other nutrients, water, and essential ions materials pass out of the renal tubules and enter the surrounding capillaries

11. Nephron in the Excretory System, Secretion
Secretion is the passage of certain substances out of the capillaries directly into the renal tubules. Tubular secretion is another way of getting waste materials into the urine

13. Disorders of the Excretory System Kidney Stone
Small, hard deposits that form inside your kidneys. The stones are made of mineral and acid salts
Severe pain in the side and back, below the ribs, pain that spreads to the lower abdomen and groin, pain that comes in waves and fluctuates in intensity, pain on urination
Kidney stones are most common in adults age 40 and older, though kidney stones may occur at any age
8.8% of people will get kidney stones
Surgery is sometimes needed to remove the kidney stone

14. Disorders of the Excretory System Glomerulonephritis
Inflammation of the Kidneys
Pink or cola-colored urine from red blood cells in your urine, foamy urine due to excess protein, high blood pressure
Glomerulonephritis may develop a week or two after recovery from a strep throat infection or, rarely, a skin infection 
Affects 4 out of every 100,000 people
Some cases of acute glomerulonephritis, especially those that follow a strep infection, tend to improve on their own and often require no specific treatment.
