1. Epithelial

1.1. Squamous

1.1.1. stratified squamous many layers of cells surface cells flat Lining of esophagus Epidermis

1.1.2. simple squmous one layer of flat cell capillaries alveoli of lungs

1.2. Transitional

1.2.1. many layers of cells surface cells change from round to flat lining of bladder

1.3. cuboidal

1.3.1. one layer cube shape thyroid salivary kidney tubules

1.4. columnar

1.4.1. one layer column shape stomach lining small intestine lining ciliated

2. connective

2.1. blood

2.1.1. fibrous pericardium sac around heart lined by sereous parietal pericardium

2.1.2. superficial fascia between skin and muscles adispose stores fat

2.1.3. within blood vessels red blood cells carry oxygen plasma (matrix) plasma white blood cells destroy pathogens platelets prevent blood loss

2.2. adispose

2.2.1. adipocytes that store fat (little matrix)

2.2.2. subcutaneous stores excess energy produces chemicals influence appetite nutrient use inflmation

2.2.3. around eyes and kidneys cushion

2.3. fiborous

2.3.1. synovial lines join cavities secrete synovial fluid prevent joint movement friction

2.3.2. mostly collagen fibers (matrix)

2.3.3. few fibroblasts

2.3.4. regular tendons ligaments strong withstand forces of movement of joints

2.3.5. irregular dermis strong inner-layer of skin

2.3.6. deep fascia covers each skeletal muscle anchors tendons

2.4. elastic

2.4.1. mostly elastin fibers (matrix)

2.4.2. few fibroblasts

2.4.3. walls of large arteries maintain blood pressure alveoli in lungs promote normal exhalation

2.5. bone

2.5.1. peristeum covers bones blood vessels that enter bone

2.5.2. bones support body protect internal organs from injury calcium storage red bone marrow contain protect

2.5.3. osteocytes in matrix of calcium salts and collagen

2.6. cartilage

2.6.1. chrondrocytes in flexible protein matrix

2.6.2. wall of trachea keeps airway open
