HKIN 241 Lecture 7: lecture 7 (one note)
Document Summary
Involves a complex series of interrelated physical and chemical activities. First event is the actual injury tissue undergoes some sort of trauma , (can be mechanical , chemical , thermal or infectious agent) Immediate disruption of tissue bleeding as a result of vascular structures namely the capillaries fluids from damages cells may leak out to the interstitial space (space between the cells) The body responds with vasoconstriction in an attempt to decrease the bleeding this usually lasts a few minutes. Blood vessels are often damaged, as a result there is an increase in blood flow to the interstitial spaces (space between cells) This results in a hematoma (or a localized collection of blood) being formed. A hematoma can develop quickly because blood flow can increase as much as 10 times. Proliferative (repair) phase: #2 redness loss of function. Body is replacing damaged or dead cells with new cells.
