abdominal and pelvic cavity Flashcards
what does the biliary system comprise of
- liver
- gallbladder
- bile ducts
- pancreatic duct
what is the liver made of up
functional units called lobules
what is the gall bladder
pear-shaped sac about 7-10cm long which is located in fossa of beneath the liver
- releases bile in small intestine
vessels carrying deoxygenated blood
- inferior vena cava
- hepatic veins
- renal veins
- common iliac veins
vessels carrying oxygenated blood
- descending aorta + its associated branches through cavity
- renal arteries
- coeliac axis + associated branches
- superior mesenteric artery + assoc branches
- inferior mesenteric artery + assoc branches
- common iliac arteries + assoc branches
what does the abdominopelvic cavity consist of
- stomach
- small intestine
- large intestine
what is the stomach and where does it lie?
- it is a continuation of the oesophagus
- lies under left hemidiaphragm
- j-shaped enlargement of GI tract
- located anteriorly
where does the inferior portion of the stomach empty into?
duodenum of small intestine
describe the size of the small intestine
- roughly 2.5cm in diameter
- 6.4m in length - eventually opens up to large intestine
where does small intestine begin and then coil into?
begins at pyloric sphincter
- coils through central and lower part of abdominal cavity
what are the 3 different segments of small intestine
- duodenum - 25cm
- jejunum - 2.5m
- ileum - 3.6m
4 portions of colon
- ascending
- transverse
- descending
- sigmoid
where are adrenal glands found
above each kidney ( suprarenal glands)
what is the pancreas?
- oblong gland which lies posterior to greater curvature of stomach
what mechanisms control pancreatic secretions
- nervous and hormonal mechanisms
large duct
pancreatic duct
smaller duct
accessory duct
what is the largest lymphatic tissue and where is it located?
- the spleen
- located within abdominopelvic cavity + posterior to stomach
gastric impression
liver has a gastric impression on its upper surface formed by the curvature of the stomach
renal impression
under surface of right lobe of liver
- corresponding to location of right kidney
colic impression
- part of visceral surface of spleen in contact with colon
- left kidney has colic impression
-presence of splenic flexure of colon
what is the spleen surrounded by?
a capsule of dense connective tissue which is covered by serous membrane
two different kinds of tissue the parenchyma of spleen consists of
- white pulp - lymphatic tissue and white blood cells
- red pulp - red blood cells involved with filtration of blood
what is the common misconception of the spleen
- does not filter lymph as there are no lymph vessels going to the spleen
