General Blood Supply & Lymphatic Drainage of the Abdomen Flashcards
What are the main arteries supplying the abdominal organs?
The main arteries supplying the abdominal organs include the celiac trunk, superior mesenteric artery, and inferior mesenteric artery.
Describe the arterial supply to the stomach.
The stomach is primarily supplied by the left gastric artery, right gastric artery, and short gastric arteries.
What are the branches of the celiac trunk?
The branches of the celiac trunk include the left gastric artery, splenic artery, and common hepatic artery.
Which artery supplies the liver?
The liver is supplied by the hepatic artery proper, a branch of the common hepatic artery.
Describe the blood supply to the spleen.
The spleen is primarily supplied by the splenic artery, a branch of the celiac trunk.
What is the arterial supply to the pancreas?
The pancreas is supplied by the pancreatic branches of the splenic artery and the superior mesenteric artery.
Name the arteries forming the hepatic arterial system.
The hepatic arterial system is formed by the common hepatic artery, proper hepatic artery, and gastroduodenal artery.
Describe the arterial supply to the small intestine.
The small intestine is supplied by branches of the superior mesenteric artery, including the jejunal and ileal arteries.
Which artery supplies the large intestine?
The large intestine is mainly supplied by the superior mesenteric artery for the right colon and the inferior mesenteric artery for the left colon.
What is the arterial supply to the kidneys?
The kidneys are supplied by the renal arteries, which arise from the abdominal aorta.
Describe the blood supply to the adrenal glands.
The adrenal glands are supplied by branches of the inferior phrenic artery, aorta, and renal arteries.
What is the arterial supply to the gonads (testes or ovaries)?
The gonads (testes or ovaries) are supplied by the testicular or ovarian arteries, respectively.
What is the venous drainage of the abdominal organs?
The venous drainage of the abdominal organs primarily occurs through the hepatic portal vein system.
Describe the venous drainage of the stomach.
The stomach is drained by the left gastric vein, right gastric vein, and short gastric veins, which ultimately join the portal vein.
What veins form the portal venous system?
The portal venous system is formed by the splenic vein, superior mesenteric vein, and inferior mesenteric vein.
What is the portal triad?
The portal triad consists of the hepatic artery, portal vein, and bile duct within the liver.
Describe the venous drainage of the liver.
The liver is drained by the hepatic veins, which ultimately empty into the inferior vena cava.
What is the significance of the hepatic portal vein?
The hepatic portal vein carries nutrient-rich blood from the digestive organs to the liver for processing.
What is the venous drainage of the spleen?
The spleen is drained by the splenic vein, which joins the superior mesenteric vein to form the portal vein.
Describe the venous drainage of the pancreas.
The pancreas is drained by the pancreatic veins, which join the splenic vein or superior mesenteric vein.
What is the venous drainage of the small intestine?
The small intestine is drained by the superior mesenteric vein, which joins the splenic vein to form the portal vein.
Describe the venous drainage of the large intestine.
The large intestine is drained by the inferior mesenteric vein, which also joins the splenic vein.
What is the venous drainage of the kidneys?
The kidneys are drained by the renal veins, which ultimately empty into the inferior vena cava.
Describe the venous drainage of the adrenal glands.
The adrenal glands are drained by the adrenal veins, which directly enter the inferior vena cava.
What is the venous drainage of the gonads (testes or ovaries)?
The gonads (testes or ovaries) are drained by the testicular or ovarian veins, respectively, which ultimately enter the inferior vena cava or the renal vein.
Describe the lymphatic drainage of the abdominal organs.
The lymphatic drainage of the abdominal organs primarily occurs through the celiac, superior mesenteric, and inferior mesenteric lymph nodes.
What are the main lymph nodes involved in abdominal lymphatic drainage?
The celiac lymph nodes receive lymph from the stomach, spleen, liver, and pancreas.
Describe the lymphatic drainage of the stomach.
The lymphatic drainage of the stomach primarily occurs through the gastric lymph nodes.
What is the significance of the cisterna chyli?
The cisterna chyli is a lymphatic sac located at the lower end of the thoracic duct, receiving lymph from the intestinal trunk.
Describe the lymphatic drainage of the intestines.
The lymphatic drainage of the intestines occurs through the mesenteric lymph nodes, which ultimately drain into the cisterna chyli and thoracic duct.
