A

drains posterior intercostal v from L side of upper posterior thoracic wall

40
Q

What makes up the IVC?

A

union of R & L common iliac V & travels thru abdomen via vena cava foramen of thoracic diaphragm to reach inferior R atrium

43
Q

What drains the lymph in the breast region?

A

axillary lymph nodes drain 75% of breast lymph

44
Q

What drains the parietal pleua?

A
