The pylorus (/ p aɪ ˈ l ɔːr ə s / or / p ɪ ˈ l oʊ r ə s /) connects the stomach to the duodenum. The pylorus is considered as having two parts, the pyloric antrum (opening to the body of the stomach) and the pyloric canal (opening to the duodenum).

Oct 30, 2023 · The pylorus is the funnel-shaped distal -most segment of the four anatomical regions of the stomach, with the others being the cardia, fundus and body of the stomach. It extends from the distal end of the body of the stomach at the angular notch to the gastroduodenal junction and is divided into two segments: the pyloric antrum and pyloric canal.

Jan 24, 2025 · The pylorus is the distal region of the stomach that acts as a junction between the stomach and the duodenum of the small intestine.[3] It regulates the passage of partially digested food (chyme) from the stomach into the duodenum.

Dec 31, 2024 · Pyloric: The pyloric region forms the stomach’s exit, channeling its contents into the duodenum. This section consists of the pyloric antrum, which connects to the main body of the stomach, and the pyloric canal, leading directly to the duodenum. The transition is regulated by the pyloric orifice, an opening controlled by the pyloric sphincter.

Feb 13, 2025 · The stomach has four main anatomical divisions; the cardia, fundus, body and pylorus: Cardia – surrounds the superior opening of the stomach at the T11 level. Fundus – the rounded, often gas filled portion superior to and left of the cardia.

Jul 17, 2023 · The stomach organ has four regions; fundus, cardia, body, and pylorus. The inner surface of the stomach is rugated to increase the surface area of the gastric mucosa allowing for gastric expansion with food ingestion.

The opening between the stomach and the small intestine is the pylorus, and the very powerful sphincter, which regulates the passage of chyme into the duodenum, is called the pyloric sphincter. The stomach is suspended from the abdominal wall by the lesser omentum.

There are four main regions in the stomach: the cardia, fundus, body, and pylorus (Figure 23.4.1). The cardia (or cardiac region) is the point where the esophagus connects to the stomach and through which food passes into the stomach. Located inferior to the diaphragm, above and to the left of the cardia, is the dome-shaped fundus.

pylorus, cone-shaped constriction in the gastrointestinal tract that demarcates the end of the stomach and the beginning of the small intestine.

The pyloric stomach forms the distal region of the stomach that opens into the small intestine. Mucosa - composed of the epithelium, lamina propria and muscularis mucosae. Gastric Pits - surface invaginations lined with surface mucous cells.
