What is a muscle sphincter?
A muscle sphincter is a band of tissue that contracts. The body has several muscle sphincters. Sphincters control back flow of acids and food from the stomach into the esophagus, and the contents of the small intestine from backing up into the stomach. The bladder sphincter controls holding and releasing urine, but helps to prevent bacteria from getting into the bladder. The anal sphincter controls elimination so we don't lose bowel movement in the wrong place or at the wrong time. Though each sphincter is strong, some conditions can wear down the effectiveness of this tissue band. Hiatal hernia can let stomach acids into the esophagus. The urinary sphincter can weaken with pregnancy, obesity, diuretics, and aging. Obesity, overuse of enemas or laxatives, anal sex, and aging can weaken the anal sphincter. Note: No organ is a muscle sphincter, but some organs have muscle sphincters. The main organs that have muscle sphincters are ones that fluid/contents can move in two directions, in and out, and serve to protect those organs from damage. So for example, the bladder is smooth muscle and as an organ has a urinary sphincter.
What are the circular bands of muscle at each end of the stomach?
These rings of muscle are not only found either end of the stomach, but also at the base of the bladder. They are called sphincters. The lower sphincter in the stomach is specifically known as the pyloric sphincter, but I regret to say I do not know the exact names given to other sphincters.
A urinary sphincter to control the flow of urine is located at each end of the urethra?
True. There is a external and internal sphincter
What is a composite attribute?
A composite attribute has multiple components, each of which is atomic or composite.

Is 22 and 11 prime or composite?
11, prime. 22, composite.
Is 37 and 42 prime or composite?
37 is prime, 42 is composite.
Is 51 and 103 a composite or prime number?
51 is composite, 103 is prime.
Is 4 and 31 prime or composite?
4 is composite, 31 is prime.
What is the metarteriole?
A Metarteriole (or arterial capillary or precapillary sphincter) is a short vessel(s) that link arterioles and capillaries. Instead of a continuous tunica media, they have individual muscle cells placed a short distance apart, each forming a precappilary sphincter that encircles the entrance to one capillary. Constriction of these sphincters reduces or shuts off blood flow through their respective capillaries and diverts blood to tissues or organs elsewhere.
