psuedostratified columnar epithelium - -This is the simple epithelium in which the nuclei
of the elongated cells are at different levels and not all the cells reach the surface.
-skeletal and cardiac muscle - -This type of muscle has striations.
-organ - -The small intestine is an example of a(n) ______ because it is composed of two or
more types of tissues that perform a particular function in the body.
-microvilli - -These are important for increasing the surface area of the cell membrane and
are not just cell junctions.
-osmosis - -The movement of water following its concentration gradient through a
selectively permeable membrane.
-facilitated diffusion - -This passive transport process uses carrier proteins to transport
lipid-insoluble molecules across the membrane.
-pinocytosis - -Generally cells use this type of endocytosis wherein the cell membrane
invaginates to endocytose a small amount of extracellular fluid.
-cartilage - -A type of connective tissue that is avascular is _____.
-atom, cell - -The _____ is the basic unit of matter and the ___ is the basic structural and
functional unit of life.
-transitional - -This epithelial tissue has dome-shaped, apical cells that appear cuboidal
when the organ is relaxed and flattened when the organ is distended by fluid.
-adipose - -A loose connective tissue that is important for protection and maintaining
body heat.
-gap junctions - -These are important in synchronizing electrical activity via ion
movement between the cells such as heart and nerves
-large amounts of extracellular matrix - -Which feature is NOT a characteristic of epithelial
tissue?
-desmosomes - -These are common in tissues subjected to friction and stretching. They
help the tissue withstand mechanical stress at a single point.
-polarity - -Epithelial tissues have an attached (basal) border and a free (apical) border.
This arrangement is known as:
