The Concerns of Excretory System
Thank you for your visit, my name is Harley Mendelson. General health and understanding of diseases have become my interest for a long time. The reason I created this website is to inform and share some of the information related to excretory diseases. I hope that the information will be beneficial for you in some way, as the right understanding does make a different about how we deal with the disease.
As you know, excretory system diseases include variety of syndrome, illnesses, and disorders related in regulating fluid and eliminating waste. These abnormal conditions interfere with the capability of how human body can facilitate waste products. Human waste is composed of toxic substances, therefore it’s crucial to get rid of these waste. Impairs in certain excretory organ can lead to major issues in regulating and removing fluid within human body.
List of Diseases:
|Kidneys||Nephritis, Nephrosis, Kidney stones, Kidney failure|
|Ureters||Ureterocele, Vesicoureteral reflux|
|Urinary Bladder||Cystitis, Bladder Cancer|
|Urethra||Urethritis, Urethral Stricture|
|Others||Urinary tract infection (UTI), Gout|
The excretory system is responsible for the excretion of nitrogenous wastes in form of urea, and the reabsorption of water and vital minerals to maintain balance in the human body. The following are large structures involve in this process are:
- Kidneys – paired organs, responsible for urine formation, has 3 main parts:
- Cortex: contains the fluid filtering mechanisms.
- Medulla – contains collecting ducts leading to renal pelvis.
- Renal pelvis – funnel shaped collecting area collects urine that then drains out of ureter.
- Ureters – long tubes leading from kidneys to the bladder.
- Urinary bladder – stores urine from ureters, covered by smooth muscle.
- Urethra – tube that takes urine out of the body with the help of the urethral sphincter, ring muscle.
Most of excretory system diseases are due to the malfunction of these structures above. Some excretory diseases can affect certain structure in the system, but it can also cause complication to the rest of the system is left untreated.
- Nephritis: swollen of one or both of the kidneys due to the inflammation of the nephron (kidney’s microscopic filtering unit). Nephritis can be caused by infection, but mostly by autoimmune disorders which affect major organs.
- Nephrosis: non-inflammatory kidney disease. Also known as Nephrotic syndrome, cause by different disorders that impair the kidney which cause the release of protein in the urine.
- Kidney stone: small, calcium deposits present in the kidney form by accumulation of mineral from our diet. These pellets could be varied in size and may descend to urinary tract.
Ureteral Diseases: mainly due to obstruction or injuries that lead to other complication.
- Ureterocele: swelling of one of ureters (tubes), usually occurs in the lower part of the tube. The urine released from the kidney may build up in the ureter and form a sac like structure. This swollen area may prevent urine’s flow to the bladder.
- Vesicoureteral reflux: common in children, but may carry in adulthood. Urine would flow back to ureters from the bladder; that could lead to infection. The cause is due to the malfunctioned valve between the bladder and ureters. This defect occurs before birth.
Urinary Bladder Diseases:
- Cystitis: inflammation of the bladder. It’s a form of UTI (urinary tract infection). Infection in the bladder can be painful, and it can also lead to serious problems if left untreated. This disease occurs more common in women.
- Bladder Cancer: there is an uncontrolled cell division in the bladder. This abnormal growing cells form a tumor. The cause is unknown, but there are links to heavy smoking, expose to harmful chemical, and radiation.
- Urethritis: inflammation of the urethra due to infection. The main cause is from bacterial infection through sexually transmitted disease.
- Urethral Stricture: is the narrowing of the urethra caused by scar tissue from injury, surgery or infection. It occurs more common in men.
Other Related Diseases:
- Urinary tract infection (UTI): is the infection of the ureters, bladder, and urethra. There are many caused related to UTI, mostly dealing with bacterial infection. Urination is painful and difficult. UTI occurs more often in women than men. Antibiotic is the common treatment.
- Gout: caused by excess uric acid stored up in the blood. It affect join, lead to pain, redness, and inflammation.
