Abdominal Cavity Flashcards
Parietal Peritoneum
Lines abdominal cavity
innermost serous layer
Visceral Peritoneum
On the organs
Covers peritoneal fascia of the organs
Greater Peritoneal Sac
In front of the stomach
Potential space for fluids
Organs fill it
Lesser Sac
Behind the stomach and slightly behind the liver
What is Mesentery?
reflections or folds of 2 peritoneum layers (parietal and visceral)
Anchors organs in their respective spaces
Lesser Omentum
superior part of stomach to liver
Fat apron
Greater Omentum
Inferior part of stomach and covers entire abdominal cavity
apron of fat
wall of infections
Hepatoduodenal Ligament
ligament from the duodenum to the liver
Contains the hepatic triad
Hepatogastric Ligament
ligament from the stomach to the liver
Mesentery
around the intestines
Transverse mesocolon
mensentery to the transverse colon
Intraperitoneal
When organs are completely covered by peritoneal
Allows them to move around but stay anchored
stomach and small intestines
Retroperitoneal
Behind parietal peritoneum
Kidneys, aorta, part of pancreas and duodenum
Secondary Retroperitoneal
Organs started as intraperitoneal and were shoved out of the way during embryology
Pancreas
Falciform Ligament
anchors the liver to the anterior abdominal wall
part of ventral mesentary
Ligamentum Teres Hapatis
Round ligament comes from umbilical vein
Lateral Umbilical Fold
houses inferior epigastric vessels
Helps demarcate hernias
Medial Umbilical Fold
Houses the umbilical ligament
not much function in adults
Median Umbilical Fold
Houses the Urachus
Helped with fetal circulation
Urachus
connection between umbilical cord and bladder in fetus
Omental Bursa
space behind the stomach
formed from the hepatogastric ligament and hepatoduodenal ligament
Hepatic Triad
- Proper Hepatic Artery
- Portal Vein
- Common Bile Duct
Epiploic Foramen
Passage way that connects the Greater Peritoneal Sac and the Lesser Sac
Foregut
From esophagus to superior half of duodenum.
Includes liver, spleen, pancreas & biliary system (Liver, gallbladder, and their ducts). Arterial supply from celiac trunk.
Esophagus
In thoracic cavity and a small portion in the abdominal cavity to connect to the stomach
Esophagogastric Juntion connection to the stomach
Parts of the stomach
Cardiac (right after cardiac sphincter) Fundus (upper left area) Body Lesser Curvature Greater Curvature Pyloric region (pyloric sphincter)
Rugae
wrinkles inside the stomach that increase surface area to allow expansion
Hiatal Hernias
Part of stomach comes out with esophagus into the thoracic cavity
Duodenum
1st part of small intestine It has 4 parts: 1. Superior duodenal cap 2. Descending (receives Common Bile Duct) 3. Horizontal 4. ascending
Where does the Foregut end?
Between the Horizontal and Ascending regions of the small intestine
Pancreas
Both and endocrine and an exocrine gland
Endocrine part of the pancreas
produces insulin
Exocrine part of the pancreas
produces pancreatic juices and sends them to the major duodenal papilla
Spleen
Lymphoid organ- all RBC go to the spleen to be recycled
