What else is it about the skin that protects individuals from injury and disease? -Correct
Answer ✔Pathogens can be sloughed off by mechanical means, such as falling off in
dead skin cells, coughing or sneezing, vomiting, or flushing from the urinary tract in
urine.
How might the characteristics of skin and the bodily fluids associated with it also help to
protect us from infection? -Correct Answer ✔There is a low pH on the skin and stomach
that generally inhibits microorganisms
If inflammation is considered a first responder and may be considered to be a hero, at
least when it is in a controlled state, what heroic acts may be attributed to it? How might
the swelling associated with inflammation actually help with the healing process?
Erythema and warmth at a site of injury typically cause discomfort, but how might one
take solace in the fact that the response is being initiated? -Correct Answer ✔It prevents
and/or limits infection and additional damage by initiating the influx of plasma, plasma
proteins, plasma enzymes, and the distribution of leukocytes from the blood vessels to
the injury. It recruits members of the adaptive immunity community to launch a more
specific defense against the pathogens and enhances the healing process.
What causes redness at the site of inflammation? -Correct Answer ✔Vasodilation of
arterioles from the histamine triggered by mediators or mast cells but then spasm to
stop the bleeding
What is brought to the injured site when the vasodilation occurs? -Correct Answer
✔Neutrophils, monocytes, oxygen, nutrients to dilute toxins
With vasodilation that dilates the capillaries, what lines the vessels? -Correct Answer
✔Leukocytes
How do the traveling leukocytes (neutrophils and monocytes) arrive at the tissue where
the site of the infection is present? -Correct Answer ✔The cell squeeze through the
gaps in the capillary walls to enter at the site of the infection
What does phagocytosis do at the site? -Correct Answer ✔Digests the foreign
substances cellular debris
Why is fibrinogen important at the site of injury? -Correct Answer ✔Fibrinogen
transforms into fibrin to wall off the injured area, taking the foreign substances to make
a mesh to support blood clotting and healing
