What happens to blood flow in the skin when you are cold?
Vessels dilate and blood flow increases to the skin to maintain warmth.
Vessels constrict and blood is bypassed from the skin to keep internal organs warmer.
Blood flow remains constant regardless of temperature.
Blood vessels in the skin expand to trap heat.
What is the primary function of vasoconstriction during the hemostasis phase of wound healing?
To increase blood flow to the wound
To tighten blood vessels and reduce blood loss
To release histamine and cause swelling
To remove debris and bacteria from the wound
What is the role of mast cells (inflammatory WBC) during the inflammation phase of wound healing?
To release histamine, causing vessels to dilate and increase swelling
To form a clot and stop bleeding
To remove debris and bacteria from the wound
To tighten blood vessels and reduce blood loss
What is the primary role of fibroblasts during the proliferation phase of wound healing?
To form new blood vessels
To lay down collagen fibers
To migrate epithelial cells across the wound
To protect the wound with a scab
During the remodeling (maturation) phase of wound healing, what happens to collagen?
It forms new blood vessels
It reorganizes to increase tensile strength
It migrates across the wound to close it
It becomes less flexible and forms scar tissue
Which of the following occurs during the remodeling (maturation) phase of wound healing?
Fibroblasts lay down collagen fibers
Epithelial cells migrate across the wound
Scar tissue forms
New blood vessels form through angiogenesis
