One of the inflammatory responses is vasodilation of blood vessels. This allows ____ and results in _____.
white blood cells and nutrients to get to site of injury quicker; redness
white blood cells to leave blood vessels at site of injury: redness
white blood cells and nutrients to get to site of injury quicker; swelling
white blood cells to leave blood vessels at site of injury; edema
The Correct Answer is A
A. white blood cells and nutrients to get to site of injury quicker; redness: Vasodilation increases blood flow, bringing immune cells and nutrients quickly to the site. Increased blood flow also causes redness (rubor), a classic sign of inflammation.
B. white blood cells to leave blood vessels at site of injury; redness: While WBCs do exit blood vessels during inflammation (diapedesis), redness is more directly caused by increased blood flow, not by WBC migration.
C. white blood cells and nutrients to get to site of injury quicker; swelling: Vasodilation leads to increased blood flow (causing redness), while swelling (tumor) is more due to increased vascular permeability and fluid leakage.
D. white blood cells to leave blood vessels at site of injury; edema: This describes part of the inflammatory process correctly (WBC extravasation and edema), but vasodilation itself mainly leads to increased blood flow and redness, not edema.

Correct Answer is C
Explanation
A. stable; epithelium: Epithelium consists of labile cells, not stable ones. These cells divide frequently even without injury.
B. permanent; nervous: Nervous tissue is considered permanent, and neurons generally do not regenerate or undergo mitosis even after injury.
C. stable; liver: Stable cells do not divide under normal conditions but can be stimulated to divide after injury. Liver cells are a classic example.
D. permanent; liver: In The liver is capable of regeneration and therefore has stable, not permanent, cells.
E. labile; epithelium: This is a true match, but it does not answer the question asked. Labile cells divide regularly and are not "usually non-mitotic" as the question specifies.
Correct Answer is E
Explanation
A. pollination
This refers to the transfer of pollen in plants; unrelated to skin physiology.
B. keratinization
Keratinization is the process by which skin cells produce keratin and move upward in the epidermis, but it does not refer to shedding.
C. denaturation
Denaturation refers to the alteration of protein structure due to heat, pH, or chemicals-doesn’t apply to normal skin turnover.
D. germination
Germination refers to seed sprouting in plants, not skin cell behavior.
E. desquamation
Desquamation is the shedding of dead, keratinized cells from the outermost layer of the skin (stratum corneum).
