What is urinary system and its function?

User Avatar

Asked by Wiki User

The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a Plumbing system to drain urine from the kidneys, store it, and then release it during urination. Besides filtering and eliminating wastes from the body, the urinary system also maintains the homeostasis of water, ions, pH, blood pressure, calcium and red blood cells.

The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein.

How do eunuchs pee when they don't have penises?

Asked by Wiki User

They would usually put a splint in the urethra to keep it from healing over. They also would give them a lot of wine and that would make them pee all the time so that the hole wouldn't heal over.

In addition: according to a book written by a woman whose grandmother lived in a harem, after the hole finally healed, eunuchs carried a small thin straw in their turbans which they would insert for urination.

Many young boys died in the process of making eunuchs. A sword would be heated red hot and the genitalia would be cut off with it. The area would be cauterized by the sword, of course. Then after a splint was inserted, the wound would be covered with animal dung in an attempt to heal it.

Throughout history, of course there have been other methods, all painful in the extreme.

Except as part of transgender surgery (which restructures the urinary flow), simple castration does not involve the penis, but only the testicles. Even these may not be removed in the process, merely rendered incapable of providing sperm or continuing the production of male hormones.

Is it ok for a boy to go pee with another boy?

User Avatar

Asked by Wiki User

Not if he's 14, but when they are 10 and under, sure. When I was a boy I urinated into the toilet at the same time as my brother. Hence the whole expression about [urine] sword fights that are common today to talk about. Just make sure they don't hold each others penises or do any fondling. That would be grounds for a penalty, not to mention possible gay behavior.

What causes greasy urine?

User Avatar

Asked by Wiki User

There is no process in the body that would cause urine to be greasy. If ut seems that urine is greasy then look for something outside the body, such as Vaseline or ointments used in that area.

The most common reason or term for a distended uterus is pregnancy. Though there are other reasons for a distended uterus like leiomyomas which are also known as uterine fibroids, any symptoms should be checked out by a physician.

What are some of the substances filtered from the blood by the kidney?

User Avatar

Asked by Wiki User

substances that are excreted from the kidneys are urea, uric acid, creatinine, toxins, drugs, plasma inorganic ions,(Na+,K+,Ca2+..ect.) H+, HCO3-, of course H2O, and anything else the body doesn't need that's found in the blood plasma.

substances that are reabsorbed are amino acids, proteins, glucose, water, plasma inorganic ions and anything the body needs that is found in the blood plasma.

the nephrons are nonselective and secrete everything in the plasma, and the capillaries then reabsorb the vitamins minerals nutrients ect. that the body needs back into the blood, everything the body doesnt need goes to the bladder. What will cause the kidneys to lose more water from the blood? Diuretic hormones

How does the urinary system remove wastes from the body?

User Avatar

Asked by Wiki User

The urinary system filters waste from the blood and produces urine in the kidneys; then it removes the urine from the body. Adults produce about a quart and a half of urine every day, but that amount can vary greatly depending on how much fluid and what types of foods are consumed and how much fluid is lost by sweating or breathing.

Two bean-shaped organs called the kidneys are found in the abdomen, near the back and just below the ribs. The kidneys are responsible for filtering the blood. The filtrate, as it moves through the kidney tubules, is modified to produce urine. The two kidneys lie behind the peritoneum on the posterior abdominal wall near the 12th thoracic and first three lumbar vertebrae. The right kidney is slightly lower than the left kidney. Each kidney and suprarenal gland is encased in a perinephric fat capsule, which is covered by a membranous renal fascia. Paranephric fat lies outside of the renal fascia.

Each kidney is shaped like a kidney bean (surprised) with an anterior and posterior surface. The renal hilum is located at the medial border and allows the renal artery to enter the kidney and the renal vein to leave. It also allows the ureter to exit the kidney. The internal part of the kidney includes a section called the medulla surrounded by a covering called the cortex. The medulla contains minor calyces that merge to form major calyces. The innermost renal pelvis is formed by the merger of the major calyces.

The body needs a way to store the urine until you have a convenient time to urinate (remove urine from the body). Urine leaves the kidneys and travels down the ureters to the bladder is a thin-walled, bag-like organ that can hold up to two cups of urine.

The bladder is connected to the urethra, which is a tube that opens externally through an opening called the external meatus.Sphincter muscles keep urine from leaving the bladder until the person is ready to urinate. The female urethra is quite short, whereas the male urethra is longer and runs through the penis.

Sometimes in the process of filtering blood and forming urine, salt-and-mineral crystals form in the kidneys. These kidney stones can travel down the ureters and into the bladder. The stones vary in size, and in some cases passing kidney stones can be extremely painful. The stones can become lodged in the ureter, blocking the flow of urine and causing a back-up of urine in the kidney. Treatments include medications and the use of lithotripsy (shock waves) to reduce the size of the stone so that it is more easily passed.
