False

Front 14

When tissues are damaged, platelets release serotonin at the site of the injury which causes local blood vessels to vasospasm in an attempt to decrease blood loss

Back 14

True

Front 39

The bronchial glands BLANK more mucus

Back 39

Back 40

Tears

Front 41

This is life threatening; from massive release of histamine after exposure to an allergen

Nasal

Front 45

Another word for redness

Back 45

Erythema

Front 46

What does histamine do to capillary permeability? To blood vessel diameter?

Back 46

- dilates capillaries in skin causing flushing

- increases capillary permeability

- this allows fluid to flow into subcutaneous tissues resulting in edema

- causes vasodilation

=decreased BP
