painful cervical lymph nodes

What structures are located near the opening of the nasal cavity in the upper throat and are also called the adenoids?

pharyngeal tonsils

low plasma level of antibodies is called?

primary response

The thoracic duct

receives lymph from large lymphatic vessels that drain the left side of the body.

activation of mast cells causes?

release of histamine

The spleen

removes worn-out blood cells from circulation

a severe anaphylatic reaction causes death by?

respiratory obstruction

Lymph from the right arm and the right side of the head and thorax drains into the

right lymphatic duct

phagocytosis does not require a?

specific antigen

If proteins are allowed to accumulate in the interstitial space, they will

"hold water" and cause edema

Which of the following conditions is most likely to cause a platelet deficiency?

Which of the following is true about lymph? It is

Absorbed by lymphatic capillaries from interstitium

represents specific immunity?

B & T cells

most associated with plasma and antibodies?

B cells

HIV attacks the helper T cells, thereby:

Depressing t-cell function Making the person more prone to infection Depressing b-cell function

a person has an infection and his phagocytes respond appropriately by releasing pyrogens, thereby resetting the bodys thermostat. What happens next?

He shivers, thereby producing heat.
