Q

A

Shunt
Blood flows from arteries directly to vein, temporary bypassing existing capillaries
occurs in hands feet and ear where they reduce heat loss in cold weather by allowing warm blood to bypass this area

39
Descending aorta has two parts
Thoracic aorta - descending aorta above diaphragm Abnormal aorta - descending aorta below diaphragm, ends near L4 vertebra where it divides into right left common iliac arteries
40
Thoracic aorta
Multiple small branches Posterior intercostal arteries- Supplies blood to posterior ribs and intercostal muscles
41

71
Hepatic veins
Inferior to the diaphragm exist superior liver, drains blood from liver into IVC
72
Haptic portal vein
Enters inferior liver, drains blood from digestive organs into liver
73
Gastric vein
Drains blood from stomach drains into hepatic portal vein
74
Splenic vein
Drains blood from spleen and pancreas to hepatic portal vein
75
Superior mesenteric vein
Drains blood from the small intestine and proximal half of large intestine into hepatic portal vein
76
Inferior mesenteric vein
Drain blood from distal half of large intestine into hepatic portal vein
77
Almost all venous blood drains from the stomach and intestines flow through the liver before entering the IVC why
Deliver processes nutrients absorbed by digestive system helps to filter any toxins
78
Venous blood drainage from stomach and intestines flow through the Liver is considered what System and why
Considered a portal system because there are two capillary beds capillary bed one is located in digestive organs Capillary two is located in the liver
