The double-layered folds of peritoneum that support the portions of the small intestine are called mesentery. The mesentery provides a pathway for blood vessels, nerves, and lymphatics to reach the intestines, in addition to supporting and holding them in place within the abdominal cavity.
Is the anatomical space behind (retro) the abdominal cavity.Structures that lie behind the peritoneum are termed retroperitoneal.Kidneys, Bladder, Pancreas, Vena Cava, Aorta, parts of the Duodenum, portions of the Colon, Reproductive organs.In your abdominal cavity is a membrane called the peritoneum, the intermost lining is the visceral peritoneum, which adheres to and supports the organs. the parietal peritoneum is the outer lining that adheres to the walls of the abdominal cavity. There is a space in between the two linings that has a potential for space that some organs actually lie in or are partialy in which is called the peritoneal cavity. those organs are said to be RETROPERITONEAL.
The frontal (also known as coronal) seperates the heart into anterior and posterior portions.
The sagittal plane divides the body into left and right portions, not interior and posterior portions. The coronal plane divides the body into anterior and posterior portions.
Frontal
Retroperitoneal organs are found behind the peritoneum, between it and the abdominal wall. These include the kidneys, adrenals, and pancreas.Primarily retroperitoneal:urinary adrenal glandskidneysdigestive esophagus (partially)small intestine (partially; for example duedonum with the exception of its first part)ascending colon and descending colonrectum (part, lower third is extraperitoneal)
Its Frontal (coronal) plane
The body is divided into anterior (front) and posterior (back) portions by the frontal (coronal) plane. This plane runs vertically from side to side and divides the body into front and back halves.
Anterior and posterior portions. It divides the body into front and back portions.
The retroperitoneum is the anatomical space located behind the peritoneum, which is the membrane lining the abdominal cavity. Its primary function is to house and protect vital structures, including the kidneys, adrenal glands, aorta, inferior vena cava, and portions of the digestive tract. Additionally, it serves as a conduit for blood vessels and nerves that supply these organs, playing a crucial role in maintaining the overall function and stability of the abdominal cavity.
The abdominal cavity.
Portions of the large intestine are found in all four quadrants of the abdomen. Because of its path of travel, each quadrant has a piece.
