Arteria gastrica sinistra, also known as the left gastric artery, is a blood vessel that supplies the stomach and the esophagus. The IPA phonetic transcription for the spelling of this word is ɑrˈtɛriə ɡæsˈtɹɪkə sɪnɪstɹə. The "a" sound in "arteria" is pronounced with an open back unrounded vowel, while the "g" sound in "gastrica" is pronounced as a velar stop. The "i" sound in "sinistra" is pronounced as a close front unrounded vowel, and the "r" sound is pronounced with a flap or tap.
Arteria Gastrica Sinistra is a medical term that refers to the left gastric artery. In human anatomy, an artery is a blood vessel that carries oxygenated blood away from the heart and delivers it to various parts of the body. The left gastric artery specifically arises from the celiac trunk, which is a major branch of the abdominal aorta.
The left gastric artery plays a crucial role in supplying blood to the stomach. It typically follows a course along the lesser curvature of the stomach, running parallel to the lesser omentum. As it traverses this path, it gives off numerous branches that provide blood supply to different regions of the stomach.
The primary function of the arteria gastrica sinistra is to deliver oxygen and nutrients to the stomach tissues, ensuring their proper functioning. It participates in the support of gastric mucosa, which lines the inner surface of the stomach and aids in digestion and absorption of nutrients. Furthermore, the arteria gastrica sinistra is responsible for maintaining the overall blood circulation within the stomach, making it an essential component of the gastrointestinal vascular system.
Understanding the anatomy and function of the arteria gastrica sinistra is important for medical professionals, such as surgeons and interventional radiologists, as it assists in diagnosing and treating various stomach-related disorders, including gastric ulcers, gastrointestinal bleeding, and gastric cancer.
