What else is it about the skin that protects individuals from injury and disease? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔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? - ✔✔Neutrophils, monocytes, oxygen,
nutrients to dilute toxins
With vasodilation that dilates the capillaries, what lines the vessels? - ✔✔Leukocytes
How do the traveling leukocytes (neutrophils and monocytes) arrive at the tissue where the site of the
infection is present? - ✔✔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? - ✔✔Digests the foreign substances cellular debris
Why is fibrinogen important at the site of injury? - ✔✔Fibrinogen transforms into fibrin to wall off the
injured area, taking the foreign substances to make a mesh to support blood clotting and healing
When the injury occurs, what stimulates the pain receptors? - ✔✔Prostaglandins
Why does the hypothalamus increase the body temperature? - ✔✔Pyrogens are released by
macrophages when exposed to bacteria
What reaction in the body inhibits bacterial growth and causes the liver and spleen to remove iron in the
body that some bacteria use for growth? - ✔✔fever
What do cells release when they are attacked by viruses? - ✔✔inferferons
Where do interferons travel to and why? - ✔✔They spread the infected cells to trigger the making of
enzymes that would inhibit the viral replication
