Cellular Reaction to Injury

Question 1

Homeostasis

Answer 1

attempt by cells to maintain a relatively stable environment

Question 2

Adaptation

Answer 2

as cells encounter changes in their environments, they respond in a process called adaptation

Question 3

Degeneration

Answer 3

the deterioration of tissues with corresponding functional impairment as a result of injury or disease

Question 4

Cellular Senescence

Answer 4

leads to alterations in cell’s abilities to replicate and repair, resulting in cellular degeneration leading to death of the cell

Question 5

Cellular swelling

Answer 5

occurs when cells are unable to maintain the proper balance and concentration between ions and fluid levels

Question 6

Osmotic pressure

Answer 6

the pressure that develops when two solution s of different concentrations are separated by a semipermeable membrane

varies with the concentration of the solution and with temperature increase

Question 7

Isotonic

Answer 7

solutions exerting the same osmotic pressure as within the cell

Question 8

Hypertonic solution

Answer 8

solution with a stronger osmotic pressure than the cell

a cell placed in a hypertonic solution will shrink

Question 9

Hypotonic solution

Answer 9

weaker pressure; less concentrated; swell cell
