A2:Characteristics of tissues Flashcards
What are Epithelial tissues?
Epithelial are the linings of the internal and external surfaces and body cavities.
what is the function of squamous epithelia?
- provide protection
- allow materials to pass through via diffusion and osmosis
What is the location of squamous epithelia?
- lungs in the alveoli
- blood capillaries
- Bowman’s capsules of nephrons
What is the function of Cuboidal epithelia?
- line ducts and tubes
- occur in glandular tissues making secretions
What is the location of Cuboidal epithelia?
- kidney tubules
- sweat ducts
- the thyroid gland and breast tissues
What is the function of columnar epithelia?
The epithelium in the stomach and digestive tract provides a barrier against bacteria and only allows necessary ions to pass through.
What is the location of columnar epithelia?
- The trachea and bronchi
- Villi in the small intesstines
what is the function of neurons?
transmit nerve impulses to other neurons,muscles and glands
What is the location of neurons?
Brain and spinal cord
What is the function of neuroglia?
- offer support and protection to the neurons
- form myekin and assist in homeostasis
What is the location of neuroglia?
Brain and spinal cord
what is the function of Blood?
they transport respiratory gases, wastes, nutrients, immune response, and blood clotting.
What is the location of blood?
contained within blood vessels
What is the function of cartilage?
-protects the bone ends from friction during movement and forms the major part of the nose and the external ear flaps.
What is the location of cartilage?
- ear
- joints
- bones
- spine
- nose
- lungs
What is the function of Bone?
- protect vital weaker tissues
- Provide shape and support
What is the location of bone?
- skull
- ribs
- arms
- legs
- spine
What is the function of areolar tissue?
- binds muscle groups, blood vessels, and nerves together.
- offers a degree of support to the tissue it surrounds
What is the location of areolar tissue?
The skin
What is the function of adipose tissue?
-helps to insulate the body against changes to the external temperature
What is the location of Adipose tissue?
under the skin and around organs such as the heart
What is the function of stratified?
helps to move the bones of the skeleton
What is the location of the Stratified muscle?
attached to the bones of the skeleton
What is the function of non-stratified muscle?
used in internal processes and functions such as peristasis
What is the location of non-stratified muscle?
around hollow organs such as the stomach
What is the function of the Cardiac Muscle?
it keeps the heart beating
What is the location of Cardiac Muscle?
The heart
What is the function of a simple compound?
Consists of several layers of cells, the outer layer of which may be worn away
What is the location of a simple compound?
The skin
What is the function of Keratinised Compound?
- the outer area: the skin is dead
- Filled with a protein called keratin which gives the tissue a waterproof outer layer
