6+7 review Flashcards
primary function of the skin
protection
type of pathogen that is a living organism that does not have a nucleus
Bacteria
examples of microbe
archae, bacteria, protozoa, fungi, viruses and prions
Genetic Mechanism
mutated genes cause production of abnormal proteins
Infectious Mechanism
pathogenic organism or particles damage the body
Neoplastic Mechanism
abnormal tissue growth
Traumatic Mechanism
injury caused by physical or chemical agents
Metabolic Mechanism
malnutrition
Inflammatory Mechanism
inflammation contribute to tissue injury
Autoimmunity Mechanism
faulty response or overreaction of immune system causing attack of body
Degeneration
breaking apart of tissues by means of unknown process
Aseptic Technique
method used to prevent contamination with microorganism
1st layer of skin
epidermis; outermost layer of skin
2nd layer of skin
dermis; deeper of the 2 layers
3rd layer of skin
subcutaneous tissue; hypodermis
symptoms
subjective, personal feelings
signs
objective, uses 5 senses to observe
risk factors of disease
Genetic factors, age, lifestyle, stress, environmental factors, preexisting conditons
aerobic
needs oxygen to grow
anaerobic
does not need oxygen to grow
warning signs of cancer
unusual bleeding, sores that do not heal, change in wart or mole, lump or thickening of tissue, persistent cough, chronic indigestion or difficulty swallowing
hyperplasia
too many cells
anaplasia
abnormal, undifferentiated tumor cells
what happens to blood vessel during inflammatory response
blood vessels get wider; dilate
signs of inflammatory response
blood vessels dilate, redness, swelling, heat, increased blood volume, pain, loss of function
epithelial membranes
composed of tissue and underlying layer of fibrous connective tissue
3 types of epithelial membranes
cutaneous membrane, serous membrane, mucous membrane
cutaneous membrane
skin (outermost layer), primary organ of integumentary system, largest organ
serous membrane
found on surfaces of closed cavities, made of epithelial sheet and connective tissue layer
mucous membrane
lines body surface opening directly to exterior of body
what is the rule of nine used for
determine the size of a burn
most serious skin cancer developed from a mole
melanoma
parietal pleura
lines the wall of body cavity; located in thoracic cavity lining
visceral pleura
covers organs, located in thoracic cavity
type of membrane the pleura in thoracic cavity is
serous membrane
HIV can be spread by
sexual contact, sharing syringes and needles with HIV positive people, exposure at birth
inflammatory mediators
attract white blood cells to the injury
