Exam 3 - Venous System of the Thorax and Abdomen Flashcards
What is the purpose of the hepatic portal vein?
to carry nutrients, bugs, and drugs absorbed from the gut into the liver to detoxify/modify
Where does a drug get absorbed into if it is placed underneath the tongue?
via the lingual veins
How do drugs that get swallowed enter the circulatory system?
they get absorbed through the gut, filtered through the liver and into the venous system
What is the hepatic portal vein formed by?
the union of the gastroduodenal vein, splenic vein, the cranial and caudal mesenteric veins
Where does the hepatic portal vein enter the liver at?
the hepatic porta
Where does the hepatic artery open into?
the hepatic porta
Where does the hepatic artery and the hepatic portal vein drain into?
the central vein
What type if blood is in the central vein?
venous blood and oxygenated blood
What forms the hepatic veins?
the union of multiple central veins
What do the hepatic veins empty into?
the caudal vena cava from the dorsal border of the liver
What is the caudal vena cava formed by?
the union of the two external and internal iliac veins and the median/mid sacral vein
What doe the caudal vena cava receive blood from?
deep circumflex iliac vein, lumbar veins, right testicular/ovarian vein, renal veins, cranial abdominal vein, hepatic veins
What does the left gonadal vein empty into?
the left renal vein
What does the caudal vena cava empty into?
the right atrium
What is the cranial vena cava formed by?
the union of the external jugular veins and the brachiocephalic vein
What do the jugular veins drain blood from?
the head and the neck
What is the external jugular vein formed by?
the union of the linguofacial vein and the maxillary vein
What is the linguofacial vein formed by?
the lingual and the facial vein
What is the purpose of the hyoid arch vein?
to connect the linguofacial vein of the right side to the linguofacial vein of the left side
What veins independently feed into the external jugular?
omobrachial, cephalic, superficial cervical, subclavian
What forms the cranial vena cava?
the union of the two brachiocephalic veins
What does the cranial vena cava directly receive?
the costocervical-vertebral trunk and internal thoracic veins
Where does the cranial vena cava empty into?
the right atrium
If the azygos vein does not feed directly into the right atrium, what does it drain into?
the cranial vena cava
