(26 cards)
Lymphatic drainage of the breast
Subareolar lymphatic plexus: axillary lymph nodes, parasternal lymph nodes, and the abdominal lymph nodes
Venous drainage of the breast
Axillary vein and internal thoracic vein
What are the three arteries of the thoracic wall?
Thoracic aorta, subclavian artery, and axillary artery
What are the three branches of the internal thoracic artery (branch of the subclavian artery)?
Anterior intercostal artery, superior epigastric artery, and musculophrenic artery
What are two branches of the thoracic aorta?
Posterior intercostal artery and bronchial artery
Which side of the body is the azygous vein?
Right
Which side of the body is the hemiazygous vein?
Left (sits under the aorta)
What are the three branches of the celiac trunk?
Left gastric artery, splenic artery, and common hepatic artery
What are the three arteries that supply the superior part of the diaphragm?
Pericardiophrenic, muscoluphrenic, and superior phrenic arteries
What artery supplies the inferior part of the diaphragm?
Inferior phrenic artery
What are three branches off of the common hepatic artery?
Right gastric, gastroduodenal, and proper hepatic arteries
What side of the body is the thoracic duct on?
Right
What are the two main drainage systems?
- Thoracic duct - RLQ, LUG, LLQ
2. Right lymphatic duct - RUQ
What do the thoracic duct and right lymphatic duct drain into?
Left and right subclavian veins back to the RA of the heart
The azygous and hemiazygous veins are branches of what vein?
Common iliac vein
Where do the azygous and hemiazygous vein empty into?
Hemiazygous empties into azygous which empties into superior vena cava
Caval system
Gonadal and renal veins drain into the inferior vena cava
Portal system
Inferior mesenteric, superior mesenteric, and splenic veins drain into portal vein which goes to the liver and empties into the hepatic vein which empties into the inferior vena cava
What type of organs do the caval and portal system supply?
Caval = retroperitoneal Portal = intraperitoneal
What do the superior mesenteric artery and vein supply?
Ascending colon, transverse colon, and small intestine
What do the inferior mesenteric artery and vein supply?
Descending colon, sigmoid colon, and rectum
Where do the posterior and anterior intercostal veins drain into?
Anterior intercostal veins drain into posterior intercostal veins which drain into the azygous and hemiazygous veins
What are the five branches of the abdominal aorta?
Renal, gonadal, celiac trunk, superior mesenteric, and inferior mesenteric arteries
What are the two branches of the internal iliac artery?
Anterior and posterior divison
