Answer 1

The main arteries supplying the abdominal organs include the celiac trunk, superior mesenteric artery, and inferior mesenteric artery.

Question 2

Describe the arterial supply to the stomach.

Answer 2

The stomach is primarily supplied by the left gastric artery, right gastric artery, and short gastric arteries.

Question 3

What are the branches of the celiac trunk?

Answer 3

The branches of the celiac trunk include the left gastric artery, splenic artery, and common hepatic artery.

Question 4

Which artery supplies the liver?

Answer 4

The liver is supplied by the hepatic artery proper, a branch of the common hepatic artery.

Question 5

Describe the blood supply to the spleen.

Answer 5

The spleen is primarily supplied by the splenic artery, a branch of the celiac trunk.

Question 6

What is the arterial supply to the pancreas?

Answer 6

The pancreas is supplied by the pancreatic branches of the splenic artery and the superior mesenteric artery.

Question 7

Name the arteries forming the hepatic arterial system.

Answer 7

The hepatic arterial system is formed by the common hepatic artery, proper hepatic artery, and gastroduodenal artery.

Question 8

Describe the arterial supply to the small intestine.

Answer 8

The small intestine is supplied by branches of the superior mesenteric artery, including the jejunal and ileal arteries.

Question 9

Which artery supplies the large intestine?

Answer 9

The large intestine is mainly supplied by the superior mesenteric artery for the right colon and the inferior mesenteric artery for the left colon.

Question 10

What is the arterial supply to the kidneys?

Answer 10

The kidneys are supplied by the renal arteries, which arise from the abdominal aorta.

Question 11

Describe the blood supply to the adrenal glands.

Answer 11

The adrenal glands are supplied by branches of the inferior phrenic artery, aorta, and renal arteries.

Question 12

What is the arterial supply to the gonads (testes or ovaries)?

Answer 12

The gonads (testes or ovaries) are supplied by the testicular or ovarian arteries, respectively.

Question 13

What is the venous drainage of the abdominal organs?

Answer 13

The venous drainage of the abdominal organs primarily occurs through the hepatic portal vein system.

Question 14

Describe the venous drainage of the stomach.

Answer 14

The stomach is drained by the left gastric vein, right gastric vein, and short gastric veins, which ultimately join the portal vein.

Question 15

What veins form the portal venous system?

Answer 15

The portal venous system is formed by the splenic vein, superior mesenteric vein, and inferior mesenteric vein.

Question 16

What is the portal triad?

Answer 16

The portal triad consists of the hepatic artery, portal vein, and bile duct within the liver.

Question 17

Describe the venous drainage of the liver.

Answer 17

The liver is drained by the hepatic veins, which ultimately empty into the inferior vena cava.

Question 18

What is the significance of the hepatic portal vein?

Answer 18

The hepatic portal vein carries nutrient-rich blood from the digestive organs to the liver for processing.

Question 19

What is the venous drainage of the spleen?

Answer 19

The spleen is drained by the splenic vein, which joins the superior mesenteric vein to form the portal vein.

Question 20

Describe the venous drainage of the pancreas.

Answer 20

The pancreas is drained by the pancreatic veins, which join the splenic vein or superior mesenteric vein.

Question 21

What is the venous drainage of the small intestine?

Answer 21

The small intestine is drained by the superior mesenteric vein, which joins the splenic vein to form the portal vein.

Question 22

Describe the venous drainage of the large intestine.

Answer 22

The large intestine is drained by the inferior mesenteric vein, which also joins the splenic vein.

Question 23

What is the venous drainage of the kidneys?

Answer 23

The kidneys are drained by the renal veins, which ultimately empty into the inferior vena cava.

Question 24

Describe the venous drainage of the adrenal glands.

Answer 24

The adrenal glands are drained by the adrenal veins, which directly enter the inferior vena cava.

Question 25

What is the venous drainage of the gonads (testes or ovaries)?

Answer 25

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.

Question 26

Describe the lymphatic drainage of the abdominal organs.

Answer 26

The lymphatic drainage of the abdominal organs primarily occurs through the celiac, superior mesenteric, and inferior mesenteric lymph nodes.

Question 27

What are the main lymph nodes involved in abdominal lymphatic drainage?

Answer 27

The celiac lymph nodes receive lymph from the stomach, spleen, liver, and pancreas.

Question 28

Describe the lymphatic drainage of the stomach.

Answer 28

The lymphatic drainage of the stomach primarily occurs through the gastric lymph nodes.

Question 29

What is the significance of the cisterna chyli?

Answer 29

The cisterna chyli is a lymphatic sac located at the lower end of the thoracic duct, receiving lymph from the intestinal trunk.

Question 30

Describe the lymphatic drainage of the intestines.

Answer 30

The lymphatic drainage of the intestines occurs through the mesenteric lymph nodes, which ultimately drain into the cisterna chyli and thoracic duct.
