       • Glandular
     • Characteristics
       • Each surface of epithelial cells have their own fuction.
       • There is littler intercellular space between adjacent plasma membranes
       • It has a high rate of cell division that allows it to repair itself
     • Functions
       • Protection, filtration, secretion, absorption and excretion
     • Example
       • Epithelia lining the intestine and kidney tubes.

2. Connective

   • Classification
     • Loose
     • Adipose
     • Blood
     • Fibrous
     • Cartilage
     • Bone
   • Characteristics
     • It is one of the most abundant and widely distributed tissues
     • Has cells that are widely separated by a matrix
     • The ground subtance is the component of the connective tissue between the cells and fibers.
   • Functions
     • It binds together, supports, strengthens other body tissues, protects and insulates internal organs, it is the primary location of stored energy reserves and is the main source of immune responses.
   • Example
     • In cartilage, the ground substance of the matrix is firm but pliable
