One of the inflammatory responses is vasodilation of blood vessels. This allows ____ and results in _____.

A.

white blood cells and nutrients to get to site of injury quicker; redness

B.

white blood cells to leave blood vessels at site of injury: redness

C.

white blood cells and nutrients to get to site of injury quicker; swelling

D.

white blood cells to leave blood vessels at site of injury; edema

Answer and Explanation

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. UV radiation
UV exposure stimulates melanocytes to increase melanin production, leading to tanning and darker pigmentation.

B. pregnancy
Hormonal changes during pregnancy, particularly estrogen and MSH, can increase pigmentation, such as in melasma (the "mask of pregnancy").

C. melanocyte stimulating hormone increased number of melanocytes
MSH stimulates melanin production, not the number of melanocytes. The number of melanocytes remains relatively stable in most individuals.

D. increased production of dark melanin
More production of eumelanin (dark melanin) leads to increased pigmentation, seen in individuals with darker skin tones or increased melanin activity.

Correct Answer is C

Explanation

A. callus formation, hematoma formation, callus ossification, remodeling of bone
Incorrect sequence. Hematoma forms first, followed by soft callus, then hard callus (ossification), then remodeling.

B. remodeling of bone, callus ossification, hematoma formation, callus formation
This sequence is completely out of order; remodeling is the final step, not the first.

C. hematoma formation, callus formation, callus ossification, remodeling of bone
This is the proper order:

  1. Hematoma(blood clot) forms immediately after fracture
  2. Callus formation(fibrocartilaginous soft callus) bridges the break
  3. Callus ossification(hard callus) replaces cartilage with bone
  4. Remodelingreshapes the bone to restore structure and strength

D. callus ossification, callus formation, remodeling of bone, hematoma formation
Incorrect-chronologically reversed.

E. hematoma formation, callus ossification, callus formation, remodeling of bone
The ossification step comes after the initial callus formation, not before.
