Tissues Flashcards
(25 cards)
What is the definition of tissue?
Cells working together to perform a function.
What are the four types of tissue?
- Epithelial - body linings internal and external
- Muscle - movement
- Neural - transmits electrical signals
- Connective - cushioning, storage, and support.
What is the function and location of skeletal muscle tissue?
Function: body movement
Location: combined with connective and neural tissue in the muscles.
What is the function and location of cardiac muscle tissue?
Function: circulates blood and maintains blood pressure
Location: heart.
What is the function and location of smooth muscle tissue?
Function: involuntary movements of internal organs
Location: walls of hollow internal organs.
What is the function and location of simple squamous epithelium?
Function: diffusion and filtration which allows for easy exchange of substances in the body
Location: lungs, blood vessels, and body cavities.
Looks like eggs; no good picture on here.
What is the function and location of stratified squamous epithelium?
Function: physical protection against abrasion, pathogens, and chemical attack
Location: the lining of body openings (throat, vagina, anus).
Multiple layers of flat cells.
What is the function and location of simple cuboidal epithelium?
Function: secretion and absorption
Location: glands, kidney tubules, and thyroid gland.
What is the function and location of stratified cuboidal epithelium?
Function: protection, secretion, and absorption
Location: lining of some ducts (rare).
What is the function and location of simple columnar epithelium?
Function: protection, secretion, and absorption
Location: lining of stomach, intestine, gallbladder.
What is the function and location of stratified columnar epithelium?
Function: protection
Location: small areas of the pharynx and urethra.
What is the function and location of pseudostratified columnar epithelium?
Function: protection and secretion
Location: lining of nasal cavity, trachea, and bronchi.
What do all connective tissues start as?
Stem tissue, which can develop into several types of tissue.
What is the function and location of areolar tissue?
Function: acts as a cushion
Location: most internal organs have a layer of this.
What is the function and location of adipose tissue?
Function: provides cushioning and insulates
Location: in the deeper layers of the skin surrounding organs.
Also known as fat tissue.
What is the function and location of reticular tissue?
Function: provides supporting framework
Location: liver, kidney, spleen.
What is the function and location of dense regular connective tissue?
Function: connects bones and muscles and is incredibly strong
Location: between muscles and skeletal bones (makes up tendons and ligaments).
What is the function and location of dense irregular connective tissue?
Function: provides strength to resist force from many directions
Location: in your skin, surrounding your muscles.
What is the function and location of elastic tissue?
Function: energy saver, allows vertebrae to return back to their original position after moving
Location: between vertebrae.
Looks similar to dense regular but has spaces in between the waves.
What is blood?
A fluid connective tissue.
Red - oxygen movement; White - part of your immune system.
What is lymph?
Another fluid connective tissue; the fluid that travels through the lymphatic system.
What is the function and location of hyaline cartilage?
Function: provides stiff but flexible support, reduces friction between bones
Location: major joints.
What is the function and location of elastic cartilage?
Function: provides support but can move yet return back to its original shape
Location: most of your external ear.
What is the function and location of fibrous cartilage?
Function: shock absorber
Location: in pads within knee joint, in between vertebrae discs.
