35
what dose endocrine glands do
secrete into tissue fluid or blood
36

secrete into ducts
37
what are the connective tissue proper includes
protein fibers and a ground substance of nonfibrous protient
38
3 types of glandular secretion
merocrine, apocrine, and holocrine
39
what is a merocrine gland and give and example
a fluid product released through the cell membrane by exocytosis. example salivary glands, pancreatic glands and sweet glands of the skin
40
what is apocrine and a example
cellular product and portions of the free ends of glandular cells pinch off during secretion example mammary glands, ceruminous glands lining the external acoustic meatus
41
what is holocrine and give an example
disintegrated entire cells filled with secretory products example Sebaceous glands of the skin
42
characteristics of connective tissue
comprise much of the body and are the abundant type of tissue by weight
43
function of connective tissue
binds structure, provide support, and protection, they fill space store fat, produce blood cells, protects against infection and helps repair tissue
44
what are the major cell types of connective tissue
fibroblast, mast cell, macrophages
45
what is fibroblast and function
widely distributed, large, star-shaped cells
| function: secrete proteins that become fibers
46
What are mast cells and functions
large cells, usually located near blood vessels
| function: release substance that may prevent blood clotting and promote inflammation
47
What are Macrophages and functions
motile cells sometimes attached to fibers
| functions: clear foreign particles from tissue by phagocytosis
48
what are the major connective tissue fibers
Collagenous, reticular and elastic
49
what are collagenous and function
thick, threadlike fibers of collagen with great tensile strength
function: hold structure together
50
what are elastic fiber and function
bundles of microfibrils embedded in elastin
| function: provide elastic quality to parts that stretch
51
what are reticular fibers and function
thin fibers of collagen
| function: from delicate supportive networks within tissue
52
what cells of connective tissue describes Cells in fluid gel-matrix
Areolar, adipose, reticular, dense regular, dense irregular and elastic connective tissue

67
four types of epithelial membranes
serous, mucous, cutaneous and synovial
68
What is a serous membrane
