-
Epithelial Tissue
protects body and produces secretions. (can regenerate)
-
Shearing
tearing of the skin.
-
Stratified squamous
transtional
-
-
connective tissue:
- supports, binds, protects
- provides protection for organs
- can provide nutrients to the body, stores vital nutrients such as fat or calcium
-
-
Red blood cells:
erythrocytes (carry oxygen and CO2)
-
Leukocyte
white blood cells (carry immunity; help fight pathogens)
-
Platelets
Thrombocytes (blood clotting coagulations)
-
Areolar tissue
- loose connective tissue
- highly vascular (numerous blood vessels)
- located where the body can intercept pathogens before they enter the bloodstream. Ex: mouth
-
Fibrous connective tissue:
- found where a need for flexible strength exists
- (dermis layer is the skin and in ligaments and tendons)
- blood supply to fibrous connective tissue is poor.
-
Adipose tissue:
- stores fats (lipids) as a food reserve and is found throughout the body.
- most formed prenatally and during the first year of life.
-
elastic:
can stretch to none and one-half times its original size. (found in the larynx, large arteries, alveoli (air sacs) and the external ear).
-
Hard connective tissue
- includes bones nad caritilage
- bone is the hardest
- gives the entire body structure , support, and mobility.
-
Cartilage:
tough, elastic tissue found between segments of the spinal cord and the vertebrae.
-
Membranes:
sheets of epithelial or connective tissue that act together to cover.
-
Epithelial Membranes:
1.) Mucous membranes
line the body cavities that open to the outside
-
2.) Serous:
line the body cavities that open to the inside.
-
Parietal layer
attached to the wall of the body cavity
-
Visceral layer
covering organs
-
3.) Connective membranes
- skeletal
- fascial
- superficial
- deep
-
fascial
holds organs in place
-
superficial
toward outside
-
-
organs
two or more tissues that come together
-
