In anatomy, the urethra (from Greek ο?ρήθρα – our?thrā) is a tube that connects the urinary bladder to the urinary meatus for the removal of urine from the body. In males, the urethra travels through the penis and also carries semen.
In respect to this, what is the function of the female urethra?
Anatomy and function of the female urethra. The female urethra begins at the bottom of the bladder, known as the neck. Before reaching the urethral opening, urine passes through the urethral sphincter. This is a muscular structure in the urethra that helps hold urine inside the body until it's released.
What is the function of the urethra and ureter?
Ureters, Bladder, Urethra. The first structure the urine passes through once leaving the kidneys is the ureter. There's a ureter, or tube from the kidney to the bladder, attached to each kidney.
The herpes simplex virus (HSV-1 and HSV-2) can also cause urethritis. Trichomonas is another cause of urethritis. It is a single-celled organism that is sexually transmitted. Sexually transmitted infections like gonorrhea and chlamydia are usually confined to the urethra.
The system produces urine by a process of filtration, reabsorption, and tubular secretion. The kidneys extract the soluble wastes from the bloodstream, as well as excess water, sugars, and a variety of other compounds. The resulting urine contains high concentrations of urea and other substances, including toxins.
The urethra is also an organ of the male reproductive system as it carries sperm out of the body through the penis. The flow of urine through the urethra is controlled by the internal and external urethral sphincter muscles.
Cystitis is much more common in women than men, probably because the anus (back passage) is closer to the urethra in women and the urethra is much shorter. It's not always obvious how the bacteria get into the bladder, but it can be caused by: having sex.
vesical trigone) is a smooth triangular region of the internal urinary bladder formed by the two ureteric orifices and the internal urethral orifice. The area is very sensitive to expansion and once stretched to a certain degree, the urinary bladder signals the brain of its need to empty.
The nephron (from Greek νεφρός – nephros, meaning "kidney") is the microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a tuft of capillaries called a glomerulus and an encompassing Bowman's capsule.
The organs, tubes, muscles, and nerves that work together to create, store, and carry urine are the urinary system. The urinary system includes two kidneys, two ureters, the bladder, two sphincter muscles, and the urethra.
Poor control of sphincter muscles. Sphincter muscles surround the urethra and keep it closed to hold urine in the bladder. If the nerves to the sphincter muscles are damaged, the muscles may become loose and allow leakage or stay tight when you are trying to release urine. Urine retention.
The female urethra is a relatively simple tubular structure that has the sole purpose of conducting urine from the bladder to the outside of the body.
Urethra: The urethra is the tube that carries urine from the bladder to outside of the body. In males, it has the additional function of ejaculating semen when the man reaches orgasm. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
Blood Supply and Lymphatic Drainage. The bladder is supplied mainly by the superior and inferior vesical arteries, which arise directly or indirectly from the internal iliac artery. The veins drain into the internal iliac vein.
Urethral opening, female: The urethra is the transport tube leading from the bladder to discharge urine outside the body. In females the urethra is shorter than in the male and opens above the vaginal opening, as indicated here: Impotence Slideshow Pictures.
A health care professional can check for this problem. Weak bladder muscles or a blocked urethra can cause this type of incontinence. Nerve damage from diabetes or other diseases can lead to weak bladder muscles; tumors and urinary stones can block the urethra. Overflow incontinence is rare in women.
Bladder Cancer: Symptoms and Signs
- Blood or blood clots in the urine.
- Pain or burning sensation during urination.
- Frequent urination.
- Feeling the need to urinate many times throughout the night.
- Feeling the need to urinate, but not being able to pass urine.
- Lower back pain on 1 side of the body.
Urinalysis: One way to test for bladder cancer is to check for blood in the urine (called hematuria). Urinalysis can help find some bladder cancers early, but it has not been shown to be useful as a routine screening test. Urine cytology: In this test, the doctor uses a microscope to look for cancer cells in urine.
The following factors may raise a person's risk of developing bladder cancer: Tobacco use. The most common risk factor is cigarette smoking, although smoking cigars and pipes can also raise the risk of developing bladder cancer. Smokers are 4 to 7 times more likely to develop bladder cancer than nonsmokers.
Inherited gene mutations. Some people inherit gene changes from their parents that increase their risk of bladder cancer. But bladder cancer does not often run in families, and inherited gene mutations are not thought to be a major cause of this disease.
Smokers are at least three times more likely to develop bladder cancer than non-smokers. Other risk factors include: bladder defects that are present from birth. undergoing chemotherapy and radiation therapy.
Functions of the uterus include nurturing the fertilized ovum that develops into the fetus and holding it till the baby is mature enough for birth. The ferlized ovum gets implanted into the endometrium and derives nourishment from blood vessels which develop exclusively for this purpose.
