-organ transplants and artificial insemination transmit HIV
-HIV is present in semen, blood, and breast milk

Front 6

The thoracic duct drains lymph into the venous blood at the junction of the:

Back 6

left internal jugular vein and left subclavian vein

Front 7

Lymph is?

Back 7

-aided by a pressure difference toward the thoracic region
-maintained primarily by the milking action of muscles
-it is possible because of valves in lymphatic vessels

Front 8

Specialized lymphatic capillaries in the small intestine are called ( ).

Back 8

Lacteals

Front 9

Lymphatic vessels are similar in structure to ( ) but have thinner walls and more valves.

Back 9

Veins

Front 10

The primary lymphatic organs, so called because they produce the lymphocytes for the immune system, are the ( ) and the ( ).
