61

ex of endocrine

pancreas, thyroid, pituitary

62

release secretions onto epith surfaces via ducts

exocrine

63

ex of exocrine

tears, sweat, digestive enzymes

64

3 ways exocrine glands release their secretions

exocytosis
release cytoplasm and secretions
cell bursts and releases secretions

65

3 types of endocrine glands based on secretions

serous glands
mucous glands
mixed exocrine glands

66

one unicellular exocrine gland

mucous (goblet) cells

67

diverse in appearance and funx
highly vascular
never exposed to outside environment

3 characteristics of connective tissue

68

3 components found in CT

specialized cells
extracellular protein fibers
ground substance

69

surrounds cells

matrix

70

establish structural framework for body
transport fluids and dissolved materials
protect organs
support, surround and interconnect other types of cells and tissue
store energy

funx of connective tissue

71

long, straight, unbranched; capable of resisting pulling forces; flexible but very strong

collagen fibers

72

where are collagen fibers found

tendons and ligaments

73

thinner; form branching, supporting networks

reticular fibers

74

ex of reticular fibers

liver and spleen

75

branched and wavy; easily stretched and resumes shape

elastic fibers

76

ex of elastic fibers

vocal cords and artery walls

77

most common connective tissue cell

fibroblasts

78

make components of ground substance and fibers

fibroblast

79

engulf pathogens and damaged cells

macrophages

80

stem cells to divide and differentiate into other connective tissue cells

mesenchymal cells

81

loose CT
adipose
reticular
dense reg. CT
dense irreg. CT
elastic ct

CT proper

82

blood

fluid CT

83

cartilage (hyaline, elastic, fibrocartilage)
bone

supporting CT

84

loosely organized; may contain all the cells and fibers

loose ct

85

mostly adipocytes and is fat

adipose tissue

86

create 3D supporting framework for cells

reticular tissue

87

mostly collagen fibers parallel to each other; tightly packed

dense reg. ct

88

mostly collagen fibers with no consistent pattern

dense irreg ct

89

mostly elastic fibers

elastic ct

90

fluid CT with plasma, rbc, wbc, and platelets

blood
