35
Q

what dose endocrine glands do

A

secrete into tissue fluid or blood

36
Q

what dose exocrine glands do

A

secrete into ducts

37
Q

what are the connective tissue proper includes

A

protein fibers and a ground substance of nonfibrous protient

38
Q

3 types of glandular secretion

A

merocrine, apocrine, and holocrine

39
Q

what is a merocrine gland and give and example

A

a fluid product released through the cell membrane by exocytosis. example salivary glands, pancreatic glands and sweet glands of the skin

40
Q

what is apocrine and a example

A

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
Q

what is holocrine and give an example

A

disintegrated entire cells filled with secretory products example Sebaceous glands of the skin

42
Q

characteristics of connective tissue

A

comprise much of the body and are the abundant type of tissue by weight

43
Q

function of connective tissue

A

binds structure, provide support, and protection, they fill space store fat, produce blood cells, protects against infection and helps repair tissue

44
Q

what are the major cell types of connective tissue

A

fibroblast, mast cell, macrophages

45
Q

what is fibroblast and function

A

widely distributed, large, star-shaped cells

function: secrete proteins that become fibers

46
Q

What are mast cells and functions

A

large cells, usually located near blood vessels

function: release substance that may prevent blood clotting and promote inflammation

47
Q

What are Macrophages and functions

A

motile cells sometimes attached to fibers

functions: clear foreign particles from tissue by phagocytosis

48
Q

what are the major connective tissue fibers

A

Collagenous, reticular and elastic

49
Q

what are collagenous and function

A

thick, threadlike fibers of collagen with great tensile strength
function: hold structure together

50
Q

what are elastic fiber and function

A

bundles of microfibrils embedded in elastin

function: provide elastic quality to parts that stretch

51
Q

what are reticular fibers and function

A

thin fibers of collagen

function: from delicate supportive networks within tissue

52
Q

what cells of connective tissue describes Cells in fluid gel-matrix

A

Areolar, adipose, reticular, dense regular, dense irregular and elastic connective tissue

53
Q

what cell of connective tissue describes Cells in solid gel-matrix
