The surface area of the pyloric sphincter is increased primarily through the presence of circular muscle fibers that create folds and grooves in the tissue. Additionally, the structure of the pylorus, with its thickened muscular wall, allows for greater surface interaction during the digestive process. These adaptations help regulate the passage of chyme from the stomach to the duodenum, enhancing digestive efficiency.
The area of a sphere is A=4*3.14 * r^2. Thus the area varies as the square of the radius. If the surface area is increased by a factor of 4, then the radius will have to increase by the square root of 4 which is 2.

The speed of dissolving increases with increased surface area because a larger surface area allows more solute particles to interact with the solvent at any given time. This enhanced interaction facilitates faster diffusion of solute particles into the solvent, leading to quicker dissolution. For instance, powdered substances dissolve more rapidly than solid chunks due to their greater surface area. Thus, breaking a solute into smaller pieces can significantly accelerate the dissolving process.

It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
This is called the pyloric region. A sphincter called the pyloric sphincter is found there.
The bottom of the stomach is the pyloric area, with the pyloric sphincter separating the stomach from the duodenum (first portion of the small intestine). The top of the stomach is the cardiac area with the cardiac sphincter. The pre-pyloric area is the area just above the phyloric sphincter where they do biopsies to test for an H-Pylori infection. The pyloric area consists of two parts the pyloric canal and the pyloric antrum.
the control of releasing material from the pyloric area of 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.

Convolutions of the brain provide increased surface area for more neurons to be packed in, allowing for greater processing power in a compact space. This increased surface area also enables more connections between neurons, facilitating complex information processing and cognitive functions.
increased surface area, increases output
Neurons have greatly increased surface area due to their dendrites and axons. Intestinal cells have greatly increased surface area due to microvilli on the surface of the cells that help in absorption of nutrients.
the greater the surface area the easier it is for them to reach and react with substrates
Pyloric ceca are finger-like projections found in the intestine of some animals, such as fish, amphibians, and insects. They increase the surface area of the intestine for absorption of nutrients and can also play a role in digestion and enzyme secretion.
