Where is the retro perineal cavity located?
The retroperitoneal cavity is located immediately posterior to the abdominal cavity (behind). It contains the kidneys (and so also the adrenal glands), the pancreas, and the abdominal aorta and vena cava. The walls of the abdominal cavity are covered with a serous membrane, called the peritoneum, as are most internal organs. The fluid in the membrane protects these structures and reduces friction between the organs and the cavity walls as well as between the organs themselves. The retroperitoneal space is separated from the peritoneal space by this layer of membrane covering the anterior organs e.g. liver, stomach, intestines. Both spaces are within the abdominal cavity.
The distal end of the abdominal aorta splits or bifurcate into?
The abdominal aorta splits at about the lumbosacral joint into two common iliac arteries.
How can a kidney be removed without cutting through parietal peritoneum?
Kidneys are said to be located in a retro-(behind) peritoneal position so removing them doesn't affect the parietal peritoneum.The retroperitoneal space is the part of the abdominal cavity that lies behind the peritoneum. Inside the retroperitoneal space, there are the kidneys, adrenal glands, bladder, and ureters. The aorta and inferior vena cava vessels are located within the space as well as part of the esophagus and rectum. These are called the primary retroperitoneal organs, meaning they typically form during gestation behind the peritoneum and remain there throughout development. All of the organs in the space typically feature some peritoneum tissue attached to their front, or anterior side, although no anatomical structures are generally a part of this space.
What is the name of the branches of the abdominal aorta that lead to the kidneys?
The renal arteries.
The abdominal aorta divides into what branches?
The abdominal aorta divides into two main branches: the common iliac arteries, which further divide into internal and external iliac arteries.
What is retroperitoneal?
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.

What is the most inferior portion of the aorta?
abdominal aorta The Abdominal aorta is the longest section of the aorta, beginning at the diaphragm and spanning the abdominal cavity. The Thoracic and abdominal aorta together make up the descending aorta.
Why does the position ofthe kidney retroperitoneal?
Organs are retroperitoneal if they have peritoneum on their anterior side only. Structures that are not suspended by mesentery in the abdominal cavity and that lie between the parietal peritoneum and abdominal wall are classified as retroperitoneal.
What quadrant is the bifurcation of the abdominal aorta in?
what quadrant is the bifurcation of the abdominal aorta in
What divides the aorta into a superior thoracic aorta and an inferior abdominal aorta?
The diaphragm divides the aorta into a superior thoracic aorta above the diaphragm and an inferior abdominal aorta below the diaphragm.
What divides the thoracic aorta from the inferior abdominal aorta?
The diaphragm divides the thoracic and abdominal aorta. These are both parts of the descending aorta, extending from the aortic arch.
In what portion is aorta divided?
Curved portion , thoracic aorta and abdominal aorta .
What are the four principle divisions of the aorta?
ascending aorta arch of aorta thoracic aorta abdominal aeorta
What organs in the abdominal region are retroperitoneal?
The kidneys, pancreas, and parts of the intestines (duodenum, ascending colon, descending colon) are retroperitoneal organs in the abdominal region. These organs are located behind the peritoneum, a membrane that lines the abdominal cavity.
Abdominal aorta is widely patent?
The abdominal aorta appears to be clear and open without any significant blockages or narrowing. This suggests that blood flow through this major blood vessel is unobstructed.
What is the size of the abdominal aorta?
2.5cm
