What is/are the types of fetal stem connective tissue?

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.

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.
