Connective Tissues

If this was useful to you, please tell me so that I know that I should create more of these for next test. Feel free to share any criticisms to me.



Goblet cells:
location- within columnar epithelium and pseudostratified columnar epithelium.
function- secretion of mucus.




Glial Cells:
Location- in nervous tissue
function- support and to clean up the cells





White blood cells:
location- blood
function- protect body from harmful bacteria and viruses.

Red blood Cells:
location- blood
function- transport oxygen



Pseudostratified Columnar Epithelium:

-function is secretions and movement
-location is in the lining of the respiratory tract.


Blood:

-function- it depends on which type of blood cells:
White blood cells- protect the cell
Plasma cells -create antibodies (latch onto foreign proteins that may be harmful and send out a signal to kill them)
Mast cells- inflammation (swelling to heal areas of injury)
Macrophages- phagocytosis (large particles are enveloped in a cell membrane of a larger cell and then stored there and the cell has formed into a food vacuole).
Red blood cells- carry oxygen
Plasma- fluid


Dense Regular Connective Tissues

function- binds muscles and bones
location- in tendons (part connecting bone to bone with dense regular connective tissue) and ligaments (joints connecting bone to bone)


Epithelial tissue include:


-Pseudostratified Columnar Epithelium (mentioned above)
-Simple squamous epithelium
-Simple cuboidial epithelium
-Simple columnar epithelium
-Stratified squamous epithelium


Meanings of Functions:

-filtration-trap unwanted particles from reaching underlying tissue.
-protection- keeps from physical and chemical injury, and from invasion by micro-organisms.
-absorption- the taking in of nutrients for underlying tissues.
-secretion- production and release of materials from glands.

--Simple Squamous epithelium- 

Function-

  • secretion, diffusion, & filtration
Location- air sacs of lungs, wall of capillaries, and lines of body cavities







--Simple Cuboidal epithelium- 

Function-

  • secretion & absorption
Location- kidney tubules and surface of ovaries, adrenal gland






--Simple Columnar epithelium- 

Function-

  • absorption (of nutrients) & secretion (of enzymes and mucus)
Location- digestive tract & gallbladder






--Stratified Squamous epithelium- 

Function-

  • protection
Location- skin, lines of mouth, lines of esophagus




Connective Tissues

I. Loose
    A. Areolar
    B. Adipose
II. Cartilage
    A. Hyaline Cartilage
    B. Elastic Cartilage
III. Bone
IV. Blood (Mentioned Above)


Loose:

Areolar tissue:

Function-
  • wrap/ cushion organs
Location- surrounds capillaries

Sorry guys, I messed up this video. I was so nervous and tired! Not a good mix. 



Adipose tissue:

Function-
  • insulates, stores energy, protects organs
Location- under skin, wraps kidneys and eyeballs



Cartilage:

Hyaline cartilage:

Function-
  • protects, supports, &provides framework
Location- nose, ends of bones, &rings of trachea


Elastic cartilage:

Function-
  • maintain shape
Location- external ear




Bone:

Function-
  • supports/provides framework, protects, & stores calcium.
Location- rib, humerus, & femur



Nervous Tissue

Function-
  • transmit impulses
Location- brain & spinal cord


Muscle Tissue

I. Skeletal
II. Cardiac
III. Smooth


Skeletal Muscle

Function-
  • movement
Location- bicep brachi, diaphragm


Smooth Muscle

Function-
  • propels content
Location-digestive tract, blood vessels, and uterus


Cardiac Muscle

Function-
  • pumps blood
Location- heart
