BIOL 2401 Anatomy and Physiology Exam 2
Overview Questions and Answers 2026
Latest Update
Epithelial Tissue Ans: Covers body surfaces, lines body cavities,
and forms glands.
Connective Tissue Ans: Protects and supports the body and its
organs, binds organs together, stores energy reserves as fat, and
provides immunity.
Muscular Tissue Ans: Generates physical force needed to make
body structures move and generates heat.
Nervous Tissue Ans: Detects changes in a variety of conditions
inside and outside the body and responds by generating electrical
signals called nerve impulses.
Fibroblasts Ans: Large, flat cells, with branching processes also
present in most connective tissue.
Macrophages Ans: Phagocytes that develop from monocytes—a
type of white blood cell.
Plasma Cells Ans: Reside in connective tissue, especially in
digestive canal and respiratory tracts.
Mast Cells Ans: Involved in inflammatory responses, the body's
reaction to injury or infection.

, Adipocytes Ans: Fat cells found deep in the skin and around
organs such as the heart and kidneys.
Leukocytes (WBC) Ans: Not found in significant numbers in normal
connective tissue; they migrate from blood into connective tissue
in certain conditions.
Elastic Fibers Ans: Made of elastin, can be stretched up to 150% of
their relaxed length without breaking.
Collagen Fibers Ans: Very strong, resist pulling or stretching, but
are not stiff which allows flexibility.
Reticular Fibers Ans: Consist of collagen, arranged in fine bundles
with a coating of glycoprotein.
Simple Squamous Epi Ans: Single layer of flat cells found in air
sacs of lungs and blood vessels.
Simple Cuboidal Epi Ans: Composed of single layer of cube-shaped
cells, lining of tubules of the kidneys and other glands.
Simple Columnar Epi Ans: Form single column of cells; goblet cells
are simple columnar cells that secrete mucus.
Ciliated Simple Columnar Epi Ans: Single layer of ciliated column-
like cells found in respiratory tract.
Pseudostratified Ciliated Columnar Epi Ans: Appears to have
layers due to nuclei at various levels but all cells are attached to
the basement membrane.
Stratified Squamous Epi Ans: Has apical surface made up of
squamous, flat cells located in various wet surfaces.
