The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear.

Which structure transports urine to the bladder by peristaltic?
The ureters are retroperitoneal and lead from the renal pelvis of the kidney to the trigone area at the base of the bladder. A thick muscular wall consisting of longitudinal and circular smooth muscle helps move urine toward the bladder by way of peristaltic contractions.
What is the organ that transports urine?
The urinary bladder is a hollow, muscular, and elastic organ that stores urine. Urine exits the bladder and the body through the urethra. The kidneys, ureters, bladder, and urethra make up the urinary tract, the pathway through which urine flows and is eliminated from the body.
What structure carries urine out of the kidney and where does it go?
The Ureters Move Urine from the Kidneys to the Bladder Urine drains from the renal pelvis of each kidney into the ureters. The ureters are long, thin tubes made of smooth muscle. Contractions of the smooth muscle push urine down through the ureters and into the bladder.
What structure associated with the urinary system transports urine and sperm?
The opening of the urethra — the tube that transports both semen and urine out of the body — is located at the tip of the glans penis. The penis also contains many sensitive nerve endings.
What are the main structures of the urinary system?
The kidneys, ureters, bladder, and urethra are the primary structures of the urinary system. They filter blood and remove waste from the body in the form of urine. The size and position of lower urinary structures vary with male and female anatomy.
Where is the bladder located in men?
In men, the bladder sits in front of the rectum and above the prostate gland. The wall of the bladder contains folds called rugae, and a layer of smooth muscle called the detrusor muscle. As urine fills the bladder, the rugae smooth out to accommodate the volume.
How many cups of urine is in an adult bladder?
The detrusor relaxes to hold the urine, then contracts for urination. An adult bladder is full at about half a liter, or about two cups. 4. The Female Urethra Is Shorter Than the Male Urethra. Urine produced in the kidneys passes through the ureters, collects in the bladder, and is then excreted through the urethra.
What is the function of the kidneys?
The kidneys filter blood (supplied by the renal arteries) to remove unwanted substances. They also secrete waste into the urine. 2. The Ureters Move Urine from the Kidneys to the Bladder. Urine drains from the renal pelvis of each kidney into the ureters. The ureters are long, thin tubes made of smooth muscle.
How long is the ureter?
In adults, the ureters are 25–30 cm long, about the length of a 12-inch ruler. 3. The Urinary Bladder Is a Reservoir for Urine. Urine flows through the ureters into the urinary bladder. In women, the bladder is located in front of the vagina and below the uterus.
How many times longer is the male urethra than the female?
Rotate the 3D model to view the male urethra, which is four or five times as long as the female urethra.
Which organs are located on the back of the abdominal wall?
1. Kidneys Filter Blood at the Top of the Urinary System. The kidneys are bean-shaped organs situated on the back of the abdominal wall, behind the peritoneum. The right kidney sits slightly lower than the left to accommodate the liver.
