Study Set Content:
Following an injury what is getting released
chemical mediators
example of chemical mediators
histamine and prostaglandins
What does mediators do
induce dilation of blood vessels and produce redness and heat
Increases the pressure in the tissue, which can also stimulate neurons and cause pain.
Edema
blocks the effects of histamine
antihistamine
prevents the synthesis of prostaglandins
aspirin
reduces the release of several chemical mediators
cortisone
threadlike protein fibrin which binds the edges of the wounds together
clot
The surface of the clot dries to form a
scab
The neutrophil eventually dies and can accumulate as a mixture of dead cells and fluid called
pus
The clot is replaced with
granulation tissue
a result of the contraction of fibroblasts in the granulation tissue, pulls the edges of the wound closer together
Wound contracture
The integumentary system consists of the
- skin, and accessory structures such as hair, glands, and nails.
Integument means
covering
The appearance of the integumentary system can indicate
- physiological imbalances in the body
Integumentary systems functions
Protection
Sensation
Vitamin D protection
Temparature regulation
Excretion
The skin provides protection against abrasion and ultraviolet light.
Protection
When exposed to ultraviolet light, the skin produces a molecule that can be transformed into vitamin D.
Vitamin D regulation
The integumentary system has sensory receptors that can detect heat, cold, touch, pressure, and pain.
Sensation
Small amounts of waste products are lost through the skin and in gland secretions.
Excretion
