animal tissue Flashcards
a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material.
Tissues
4 basic types of tissue
connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
supports other tissues and binds them together
connective tissue
provides a covering
epithelial tissue
includes striated muscles that move the skeleton, and smooth muscle, such as the muscles that surround the stomach.
Muscle tissue
made up of nerve cells and is used to carry “messages” to and from various parts of the body.
Nerve tissue
Tightly-joined closely-packed cells
One side of epithelium exposed to air or internal fluid, other side attached to a basement membrane, a dense mat of extracellular matrix (connective tissue)
Covers the outside of the body and lines the internal organs and cavities
Barrier against mechanical injury, invasive microorganisms, and fluid loss
Provides surface for absorption, excretion and transport of molecules
Epithelial Tissue
type of body tissue that forms the covering on all internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands.
Epithelial Tissue
Location:Air sacs of the lungs, kidney glomeruli, lining of the heart, blood vessels, and lymphatic vessels.
Function: Allows passage of materials by diffusion and filtration
Simple Squamous Epithelium
Location: Kidney tubules, ducts and small glands, and a surface of
ovary.
Function: Secretion
Simple Cuboidal Epithelium
Location: Lines of digestive tract, gallbladder and excretory ducts of some glands.
Function: Absorption, enzyme secretion
Simple Columnar Epithelium
Location: Lines the bronchi, uterine tubes and some regions of the uterus.
Function: Propels mucus or reproductive cells by ciliary action.
Pseudostratified Ciliated Columnar Epithelium
Location: Lines the esophagus, mouth, and vagina. Keratinized variety lines the surface of the skin.
Function: Protects underlying tissues in areas subject to abrasion
Stratified Squamous
Epithelium
bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage. They occur throughout the body.
Connective tissues
Location: Around kidneys,
under the skin, in bones,
within abdomen, and in
breasts.
Function: Provides reserve
fuel (lipids), insulates against
heat loss, and supports and
protects organs.
Adipose Tissue Cells
Location: Widely distributed
under the epithelia of the
human body.
Function: Wraps and
cushions organs.
Loose (Areolar) Connective Tissues
Location: Dermis of the skin, sub - mucosa of the
digestive tract, and fibrous capsules of organs and
joints.
Function: Provides structural strength.
Fibrous Connective Tissues
Location: Bones
Function: Supports, protects, provides lever system for muscles to
act on, stores calcium and fat, and forms blood cells.
Bone (Osseous) Tissue
Location: Within blood vessels.
Function: Transports oxygen, carbon dioxide, nutrients, wastes,
hormones, minerals, vitamins and other substances.
Vascular Tissue (Blood)
Location: between bones e.g. the elbows, knees and ankles. Ends of the ribs. Between the vertebrae in the spine.
Function: a strong, flexible connective tissue that protects your joints and bones. It acts as a shock absorber throughout your body.
Hyaline Cartilage tissue
is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which helps transmit nerve impulses and also provides nutrients to neurons.
Nervous or the nerve tissue
Location: Brain, spinal cord,
and nerves.
Function: Transmits electrical
signals from sensory
receptors to the spinal cord
or brain, and from the spinal
cord or brains to effectors
(muscles and glands).
Nervous Tissue
composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.
Muscle tissue
Location: In skeletal muscles
attached to bones.
Function: Voluntary
movement, locomotion.
Skeletal Muscle Tissue
Location: Mostly in the walls of
hollow organs.
Function: Moves substances or
objects (foodstuffs, urine, a baby)
along internal passageways;
involuntary control.
Smooth Muscle Tissue
Location: The walls of the heart.
Functions: As the wall of the heart
contract, cardiac muscle tissue
propels blood into the circulation;
involuntary control.
Cardiac Muscle Tissue
