They are variable controls which can open to allow the passage of material and then closed to prevent further passage of materials. If you didn't have an anal sphincter you'd really have problems.
What else can I help you with?
Is the relation a function?
Not every relation is a function. But every function is a relation. Function is just a part of relation.
The function f(x) x3 is called the function?
The cubic function.
If an inverse function undoes the work of the original function what does the original function's becomes the inverse function's domain?
Range
What are the ways in describing a function?
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
How does the graph of the Mandelbrot set function relate to composite functions?
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
Which sphincters function as regulatory valves that reduce the flow of blood through a network of capillaries when they contract and constrict the arterioles?
Precapillary sphincters
What is the purpose of sphincters?
Sphincters prevent material from flowing backwards, like the pyloric sphincter in the stomach.
Do sphincters prevent backflow?
yes !
What lets food in and out of the stomach?
sphincters
Where can a sphincter be found in the urinary system also what is its function?
A sphincter is a circular band of muscle tissue that, when contracted, cuts off the flow of material from one place to another. There are two urinary sphincters, one at the base of the bladder and one at the pelvic canal along the urethra. The purpose of both sphincters is to prevent urinary leakage.
How do arterioles regulate blood flow into capillaries?
Sphincters
What are sphincters and how are related to the stomach?
Sphincters are circumferential muscles that can relax or constrict to regulate the passage of material through a particular area. The stomach is bound by two sphincters in humans: the lower esophageal sphincter that keep stomach acid in the stomach and the pyloric sphincter that regulates the flow of food in the stomach into the duodenum.
How do precapillary sphincters help regulate blood pressure and body temperature?
the Precapillary Sphincters control blood pressure and body temperature by regulating the flow of blood to the capillary bed.
The amount of blood that flows into capillaries is regulated by?
precapillary sphincters
What are the muscles that are found at openings of the body collectively called?
Sphincters
Muscles that encircle tubes and act as valves are called?
sphincters
What are the muscles found at the openings of the body collectively called?
Sphincters
