system uses several ways to temporarily increase blood pressure when it has dropped for example during the fight or flight response. During the response‚ the sympathetic division is needed to stimulate the adrenal glands to release the hormones epinephrine and norepineprine which stimulate the heart to beat faster and for blood to flow more forcefully‚ this effect makes most of the arterioles to constrict and some arterioles dilate‚ which leads to an increase blood supply where needed. In order to

During the day‚ I observed parts of two different surgeries. The first client was in surgery for a thoracotomy to perform a lung biopsy. The surgeon said that the chest x-ray showed infiltrates and that pulmonologist wanted a tissue sample. The patient was a male approximately 60 years old. He had a large barrel chest‚ which might indicate COPD. The procedure involved making an incision in the chest between two ribs. The surgeon continued cutting and cauterizing the incision until he reach

remodeling. These phases are widely overlapping and interconnected. The first stage‚ hemostasis begins immediately after injury. Platelets consolidate around the site and cytokines‚ hormones and and chemokines are released into the surrounding area. Epinephrine‚ norepinephrine‚ serotonin‚ and thromboxane cause vasoconstriction‚ or the tightening of muscle cells to constrict blood vessels. This process helps limit further blood loss. The activated platelets attach to exposed collagen and release growth
