|---|---|---|---|---|---|
| The study of functional or physiologic changes in the body that result from disease processes | Pathophysiology
🗑
|
||||
| We need to understand that any loss or change in normal structure, then loss of function | why we need to understand pathophysiology
🗑
|
||||
| Which factors of pathophysiology helps figure out the disorder | the disorder displays a set of common set of signs and symptoms related to the organs normal structure or function.
🗑
|
||||
| An example of knowing the pathophysiology as it relates to signs and symptoms of liver disease. | When clotting factors are not produced leads to excess bleeding- liver is unable to excrete bilirubin - yellow color - inflammation- tissue swells/liver capsule swells - pain.

🗑
|
||||
| Stressors increases cell | metabolism
🗑

🗑
|
||||
| What happens when stressors are prolonged? | can cause problems with different areas of body.
🗑
|
||||

🗑
|
||||
| Stressors prolonged effect on muscleskeltal leads to | rheumatoid arthritis (RA)
🗑
|
||||
| Stressors prolonged effect on GU leads to | acute renal failure
🗑
|
||||
| Stressors prolonged effect on dermis leads to | herpes simplex, eczema, acne, impaired healing
🗑
|
||||
| Stressors prolonged effect on other areas of the body lead to | cancer and infection
🗑
|
||||
| Stressors activate which part of the nervous system? | Central nervous system
🗑
|
||||
| The central nervous system activates | Hypothalamus
🗑
|
||||
| hypothalamus | stressor turns on CNS that activates
🗑
|
||||
| Stress on the SNS signals | adrenal medulla
🗑
|
||||
| what does the adrenal medulla release | epinephrine and norepinephrine
🗑
|
||||
| Hypothalamus activates | sns and pituitary
🗑
|
||||
| adrenal medulla is activated by | SNS
🗑
|
||||
| what does the adrenal medulla release once the SNS has activated | epi and noriepinephrine
🗑
|
||||
| They hypothalamus activates the anterior pituitary to release what? | ACTH
🗑
|
||||
| Anterior Pituitary releases ACTH and activates what? | the adrenal cortex
🗑
|
||||
| Pituatary | adrenal cortex
🗑
|
||||
| SNS | adrenal medulla
🗑
|
||||
| anterior pituitary releases | ACTH to activate the adrenal cortex
🗑
|
||||
| What does the adrenal cortex released | cortisol and aldosterone
🗑
|
||||
| Posterior pituitary releases | ADH (anti-diuretic hormone)
🗑
|
||||
| ADH | retains fluid and increases the workload of the heart
🗑
|
||||
| anterior pituitary releases ACTH and activates the adrenal cortex that releases | cortisol and glucocorticoids and aldosterone & mineral corticoids
🗑
|
||||
| Cortisol, glucocorticoids, aldosterone, and mineralcorticoids are actived by | anterior pituitary gland that releases ACTH
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
