Presentation transcript:

Nonsolid wastes are eliminated through lungs, skin, and kidneys. Function: The excretory system eliminates nonsolid wastes from the body. skin lungs kidneys ureters urinary bladder urethra Nonsolid wastes are eliminated through lungs, skin, and kidneys. Lungs exhale carbon dioxide and water vapor. Sweat glands in skin release excess water and salts.

Urinary System: The ureters are tubes that carry urine from the pelvis of the kidneys to the urinary bladder. The urinary bladder temporarily stores urine until it is released from the body. The urethra is the tube that carries urine from the urinary bladder to the outside of the body. The outer end of the urethra is controlled by a circular muscle called a sphincter. skin lungs kidneys ureters urinary bladder urethra

Function of the Kidney The liver filters blood and waste is converted into urea. The principal function of the kidney is to filter urea from the blood that came from the liver in order to remove cellular waste products from the body. At any given time, 20 % of blood is in the kidneys. Humans can function with one kidney. Regulate acid-base balance

The kidneys help to maintain homeostasis by filtering the blood. cortex medulla renal artery renal vein ureter (to bladder) The kidneys are fist-sized, bean shaped structures. two layers: medulla and cortex filtering units called nephrons renal artery and renal vein

Kidney cortex ureter medulla

Kidneys have three basic functions in maintaining homeostasis. remove nitrogenous waste from blood help to maintain electrolyte, pH, and fluid balances release key hormones

All urine has ammonia which is a normal product of the NH₃ (Nitrogenous Waste) All urine has ammonia which is a normal product of the metabolism of protein. Thus, all your urine should smell a little bit like ammonia…kidney filters out nitrogenous waste.

DISORDERS OF THE EXCRETORY SYSTEM Kidney Stones Urinary Tract Infection Kidney Infection Kidney Failure

KIDNEY STONES https://www.youtube.com/watch?v=uiioP_bQVMA

Kidney Stones Crystals formed from minerals in urine. They can be found in the kidney, ureter or bladder. 80% of those stricken are males. The most common crystals are: Calcium Oxalates Uric acid

Kidney Stones (cont) Symptoms include severe back or abdomen pain, blood in the urine, nausea and vomiting. Diagnosis involves a complete medical examination, including X-rays. Treatment may vary from letting the stones pass through the urinary tract to ultrasound shock to disintegrate the stones to a small size that can be passed through the urinary tract. Real large stones require surgery for removal.

Kidney Stones (cont) Ways to avoid kidney stones: Increase liquid intake (more than 2l / day) Limit sodium intake Limit animal protein (link shown in men) Limit foods high in oxalate (spinach, strawberries, dark chocolate, brewed tea)

Injury and disease can damage kidney functions. A kidney transplant can replaced damaged kidney. recipient and donor tissue must match drugs prevent tissue rejection The daughter and son in this photo donated a kidney and liver tissue to their mother.

Dialysis can be used to filter and clean the blood.

UTI (Urinary Tract Infection) Disorders of the Excretory System UTI (Urinary Tract Infection) Is a very common disorder. If the bladder has become infected, it is known as cystitis. If the urethra is infected., it is called urethritis. Symptoms include painful urination burning sensation), frequent urination (even if no urine present) and bloody or brown urine. This can lead to chills, fever, nausea, vomiting and upper abdomen tenderness.

Also, a person should drink lots of water. NOTE : If left untreated, all UTI’s can lead to permanent kidney damage and possible kidney failure. The general treatment is by antibiotics. A person needs to maintain good personal hygiene when eliminating wastes (liquid and solid forms) from the body. Also, a person should drink lots of water.

Result when an infection reaches the kidneys. Kidney Infections Result when an infection reaches the kidneys. Common causes can be infection from elsewhere in the body or obstruction of the prostate gland (usually in older men).
