Epithelial tissue lines organs and the outside of the body, . This tissue is characterized by shape and the number of layers. These shapes are columnar (tall), squamous (flat), and cuboidal (box-like). If it has one layer, it is called "simple". If it has multiple layers, it is called "stratified".
Simple cuboidal- secretion & absorption
Simple columnar- secretion & absorption
Simple squamous- filtration
Stratified cuboidal- protection
Stratified columnar- protection & secretion
Stratified squamous- protectection of underlying tissue
The main responsibility of muscule tissue is motion. There are three types. Skeletal (voluntary), smooth (invountary), and cardiac (involuntary). Skeletal muscle tissue is the most abundant tissue in the vertebrae body and is attached to the bones. Smooth muscle tissue is made of fibres and lines the walls of hollow organs. Cardiac muscle tissue is only found in the heart.
Skeletal- movement of voluntary body parts
Smooth- controls slow, involuntary movements
Cardiac- contraction of the heart atria and ventricles
Connective tissue has living cells and a non-living matrix. There are six types of connective tissues. Loose (areolar, apidose, and reticular), dense (regular and irregular), cartilage (hyaline, fibrocartilage, and elastice), blood, bone, and fat.
-Binds tissues together
Blood tissue- transportation, controls pH, and removes toxins from the body
Bone tissue- support, protection, mineral storage, assists movement, and produces blood cells
Nervous tissue is made up of neurons. When these neurons are stimulated, they transmit impulses all over the body. A nerve is made up of neurons and bound together by connective tissue.
-Allow organisms to sense stimuli
