Question | Answer |
- contusion | is bleeding into the skin or underlying tissues as a consequence of a blow |
- abrasion | results from removal of the superficial layers of the skin caused by friction between the skin and injuring object |
- apoptosis | = a distinct type of sublethal injury, cellular self-destruction that occurs in both normal and pathologic tissue changes. This is cell death, getting rid of old cells. In some cases is routine body maintained |
- Epinephrine | exerts its affects on the Cardiovascular system |
- Norepinephrine | chief effects compliment those of epinephrine |
- Cortisols | chief effects involve metabolic processes by inhibiting the use of metabolic substances while promoting there formation |
signs of dehydration | - Water deprivation, - Hypovolemia, - Intracellular Dehydration |
- Water deprivation | confusion or coma, inability to communicate, loss of thirst, inability to swallow |
- Hypovolemia | weight loss, weak pulse, postural hypotension, Tachycardia |
- Intracellular Dehydration | Thirst, fever, decreased urine output, shrinkage of brain cells |
what damage free radicals cause | cause cellular injury B/C they have unpaired electrons that makes the molecule unstable |
How free radicals stabilize themselves | - To stabilize itself the molecule gives up an electron to another molecule or steals one. Therefore it form injurious chemical bonds w/proteins, lipids and carbohydrates (key molecules in membranes and nucleic acids |
- Isotonic | · Occur when changes in TBW are accompanied by proportional changes in electrolytes |
- Hypertonic | develop when the osmolality of the ECF, is elevated above normal, usually because of increased concentration of ECF sodium or a deficit of ECF water |
- Hypotonic | occur when the osmolatlity is less than normal |
What are some causes of edema? | - Caused by osmotic movement of water into the interstitial space |
- Hydrostatic pressure | · Pushes the water |
- Osmotic Pressure | · Pulls the water |
- Oncotic Pressure | · Remains fairly constant bc plasma proteins do not normally cross the plasma membrane |
mutation | inherited alteration of genetic material |
glycolisis | the splitting of glucose |
How many moleculkes does glycolysis produce per glucose molecule | two |
what is the total process of glycolysis called | oxidative cellular metabolism |
what is cellular injury caused from | lack of oxygen (hypoxia), free radicals, caustic or toxic chemicals, infectous agents, immune responces, geetic factors, insufficent nutrients, or physical trauma from many causes |
What are the sequence of events leading to cell death | decrease in ATP production, failure of sodium potassium pump, cellular swelling, detachment of ribosomes from the ER, cessation of protein systhesis, mitochodrial swelling as a resukt of calcium accumulation |
what is the intial result in hypoxic injury | cessation of blood flow into vessels that supply the cell with oxyen and nutrients |
what does Epinephrine increase | C.O., and blod flow to the brain and the heart, brain and skeletal muscles by dialating blood vessels that supply these organs |
How does epinephrine dialate the airways | by increaseing the delivery of oxygen to the blood stream |
What does decreasing insulin to the brain help you do (epinephrine) | Think clearly |
What effects does Norephrine do | constricts the blood vessels, increases menatl alertness |
where is norepinephrine produce | the adrenal medulla |
what is compensation with reguard to an abnormal ph | correction occurs when the value of noth buffer pairs return to normal |
What is low PH considered | acidosis |
What is high Ph considered | alkalosis |
a high PaCO2 | a lower pH |
CO2 will | "move" the pH, but other factors may still cause an alkalosis |
Respiratory mechanism | (depth and rate of breathing) controls CO2 |
CO2 in solution | is an acid |
Higher PaCO2 | causes acidosis (lower pH), or neutralizes alkalosis. |
Lower PaCO2 | causes alkalosis (raises pH.), or neutralizes acidosis. |
Metabolic mechanism controls | bicarb; amount of HCO3- is controlled by kidneys |
Bicarbonate (HCO3-) is | a base |
High HCO3- | causes alkalosis (raises pH), or neutralizes acidosis |
Low HCO3 | causes acidosis (lowers pH), or neutralizes alkalosis |
High PaCO2 and low HCO3 | (acidosis) or |
Low PaCO2 and high HCO3 | (alkalosis |
