Circulation and the integumentary system do
play vital roles with each other. Circulation helps with the regulation
function of the integumentary system. But, how do they interact with each
other? The skin and blood vessels don’t seem like something that could work
together. But, skin and blood vessels play a vital role in regulating the body’s
temperature. When the body needs to cool down, the blood vessels will widen and
bring blood closer to the surface of the skin so that the heat can be released.
If the body needs to conserve, it’s heat then the blood vessels will narrow and
keep the blood from the surface and move it towards vital organs and muscles and
warm them up.

A skin disorder that I want to talk about is
cellulitis. Cellulitis is, “an acute, spreading bacterial infection below the
surface of the skin” (CMA, pg. 522). Cellulitis occurs if there is a break in
the skin, like it someone gets a bad scratch or an animal bite. It can also be
caused by bacteria arriving from somewhere else, through the bloodstream. A couple
complications of cellulitis are getting a weakened immune system or getting
diabetes. Some symptoms of cellulitis are redness, swelling, warmth, pain,
fever, and enlarged lymph nodes. Treatment for cellulitis are topical and oral

Another skin disorder that has to do with the
circulatory system is decubitus ulcer. Decubitus ulcer is also known as a bedsore
or pressure sore. It is an area of skin or tissue that breaks down and dies
because it isn’t getting any sort of blood supply. Patients who usually get
this are ones that have been lying in bed for a long time, so maybe someone in
a coma or who just had a major surgery. Other people who get these are patients
who are in wheelchairs. The ulcers usually happen at the coccyx, hips, sacrum,
ankles, shoulders, heels, back of the head, and back. There are four different
stages of this disorder. It starts with a reddened area that doesn’t turn white
when pressed, then it moves on to a blister or open sore, then the skin breaks
down and it looks like a crater, and the final stage is that it becomes really
deep and causes damage to bone and muscle. Treatment for decubitus includes repositioning
the patient often and cleaning out the wound.

The final skin disorder that I want to talk
about is rosacea. Rosacea is a, “disorder that primarily affects the facial
skin, often characterized by flare-ups and periods of remission” (pg. 527). This
disorder doesn’t seem to affect any one group of people, it just happens to
anyone. Actually, around fourteen million Americans are affected and a lot of
them don’t even know it. Symptoms of rosacea include a redness on the cheeks,
nose, chin, or forehead. There are also tiny, but visible, blood vessels on the
face or bumps on the face. A person’s eyes can be watery or irritated. As time
goes on, the redness can become redder and persistent. There is not a cure for
rosacea, but it can be treated with cortisone-bases creams and topical
