In complex organisms, cells are organized into ____ - Answers -✔✔ Tissues
Groups of similar cells with a common function - Answers -✔✔ Tissues
The four major types of tissues in the body are ____ - Answers -✔✔ Epithelial,
Connective, Muscle, and Nerve
This major type of tissue is used for protection, excretion, secretion, and absorption that
is found covering the body surface, covering and lining he internal organs, and compose
glands. They also LACK blood vessels, cells readily divide and tightly packed. -
Answers -✔✔ Epithelial
This major type of tissue is used to bind, support, protect, fill spaces, store fat, and
produce blood cells. They are located all throughout the body with good supply and
cells are farther apart with an extracellular matrix. - Answers -✔✔ Connective
This major type of tissue is used for movement that is attached to bones, in the walls of
hollow internal organs and the heart. It is also able to contract in response to certain
stimuli - Answers -✔✔ Muscle
This major type of tissue is used to conduct impulses for coordination, regulation,
integration, and sensory reception that is found in the brain, spinal cord, and nerves.
The cells communicate with each other and body parts. - Answers -✔✔ Nervous
An intercellular junction where the membranes between cells merge and fuse, they are
located among cells that form linings, sheet like layers; blood-brain barrier, cells that line
the small intestine - Answers -✔✔ Tight junctions
An intercellular junction that form "spot welds" between cells that are structural
reinforcement, located among outer skin cells - Answers -✔✔ Desmosomes
An intercellular junction that are tubular channels between cells where molecules can
move between cells, they are located in cardiac muscle cells and digestive tract -
Answers -✔✔ Gap junctions
Helps with drug delivery across the blood-brain barrier, uses structures smaller than 100
nm in atleast 1 direction to help medications across the barrier - Answers -✔✔
Nanotechnology
, Covers organs and body surface, lines cavities and hollow organs, makes up glands,
have a free surface on outside and basement membrane on inside, usually lack blood
vessels; nutrients diffuse from underlying connective tissue, cells readily divide ; injuries
heal rapidly, cells are tightly packed, classified according to cell shape and number of
cell layers - Answers -✔✔ Epithelial
flat shape like cells - Answers -✔✔ squamous
cube shaped like cells - Answers -✔✔ cuboidal
tall shaped cells - Answers -✔✔ columnar
one layer of cells - Answers -✔✔ simple
2 or more layer of cells - Answers -✔✔ stratified
appears to be layered but is really not - Answers -✔✔ pseduostratified
Single layer of thin, flat cells; substances pass through easily; thin and delicate, can be
damaged; found in diffusion and filtration sites; lines air sacs and capillaries; lines blood
and lymphatic vessels - Answers -✔✔ Simple squamous
single layers of cube shaped cells; secretion and absorption; lines kidney tubules,
thyroid follicles; covers ovaries; lines ducts of some glands - Answers -✔✔ simple
cuboidal
single layer of elongated cells; nuclei usually at same level; near basement membrane;
sometimes have cilia, microvilli, and goblet cells that secret mucus; secretion and
absorption; lines uterus, stomach, and intestines - Answers -✔✔ simple columnar
single layer but appears layered; nuclei at 2 or more layers; cells vary in shape; often
has cilia and goblet cells; protection from infection; lines respiratory passageways -
Answers -✔✔ pseudostratified columnar
Many cell layers, thick; protective layer; outermost cells are flat; deeper cells are
cuboidal; new cells form, push older cells toward free surface; outer layer of skin
(keratinized); lines oral cavity, vagina, anal canal - Answers -✔✔ stratified squamous
2-3 layers of cube shaped cells; more protection than 1 layer; lines ducts of mammary,
sweat, and salivary glands, and pancreas - Answers -✔✔ stratified cuboidal
top layer of elongated cells; cube shaped cells in deeper layers; lines part of male
urethra, ducts of exocrine glands - Answers -✔✔ stratified columnar
