Gastrointestinal perforation is defined by a full-thickness injury to all layers of the gastrointestinal wall, resulting in a hole in the hollow GI tract (esophagus, stomach, small intestine, or large intestine). A hole can occur due to direct mechanical injury or progressive damage to the bowel wall due to various disease states.
Black stomach is a condition that results from acute gastric necrosis. The tarry black colour is produced by the coagulative necrosis of mucosa resulting in intramucosal haemorrhage and acid hematin deposition. This condition was first described in a patient with acid poisoning. [1]
The gastrovascular cavity is the primary organ of digestion and circulation in two major animal phyla: the Coelenterates or cnidarians (including jellyfish and corals) and Platyhelminthes (flatworms).
The abdominal cavity is a large body cavity in humans [1] and many other animals that contain organs.It is a part of the abdominopelvic cavity. [2] It is located below the thoracic cavity, and above the pelvic cavity.
Black holes have a role in natural selection. In fecund theory a collapsing [clarification needed] black hole causes the emergence of a new universe on the "other side", whose fundamental constant parameters (masses of elementary particles, Planck constant, elementary charge, and so forth) may differ slightly from those of the universe where the black hole collapsed.
Black holes can 'cook' their own meals, study finds. The data in the images tell a story about how giant black holes consume gas. By unleashing powerful jets, or outbursts, the black holes ...
A stellar mass black hole can pull in a substantial inflow of surrounding matter, but only if the star from which it formed was already doing so. [ 10 ] The Earth's equator does not line up with the plane of the Earth's orbit , so for half of the year the Northern Hemisphere is tilted more towards the Sun and for the other half the Northern ...
Cannon and Washburn concluded that stomach contractions play a critical role in signaling hunger to the brain. Their findings suggested that hunger could be alleviated by distending the stomach, even in the absence of food consumption. This discovery provided the first experimental evidence linking hunger to the physiological state of the ...
