general characteristics about connective tissue cells
| Question | Answer |
|---|---|
| how many tissue cells are there | 3 |
| how many tissue fibers are there | 2 |
| produces intercellular substance | connective tissue cells |
| stores fat | connective tissue |
| connective tissue makes | blood cells |
| connective tissue can | eat bacteria and debris |
| phagocytosis is | eating bacteria and debris |
| produce antibodies that give us immunity to certain diseases | connective tissue |
| makes heparin to prevent blood clotting | connective tissue |
| a type of connective tissue cell is | fibroblast |
| macrophages is a type of | connective tissue cell |
| mast cells are a type of | connective tissue cell |
| most numerous and young cells in connective tissue | fibroblasts |
| contain an abundance of rough endoplasimic recticulum | fibroblasts |
| fibroblast are | active in synthesis of protein for use in extracelluar enviornment |
| form a intercellular material necessary for growth and repair | fibroblast |
| secrets proteins that become fibers | fibroblast |
| usually attached to fibers but can detach and actively move about | macrophages |
| macrophages | specialized to carry on phagocytosis |
| carry out phagocytosis because | macrophages function as scavenger cells that can engulf foreign particles that enter tissue |
| important defense against infection | macrophages |
| macrophages | play a role in immunity |
| an important part of the reticuloendothelial system | macrophages |
| reticuloendothelial | tissues composed of scattered phagocytic cells |
| macrophages can be found in | kupffer cells in the liver |
| macrophages orginate as | white blood cells in bone marrow |
| microglia cells are found in the | brain |
| microglia are a type of | macrophage cell |
| macrophages are found in | all types of connective tissue |
| mast cells | a type of connective tissue cell |
| release heparin | mast cells |
| heparin | a anticoagulant |
| anticoagulant | prevents blood clotting |
| releases histamine | mast cells |
| histamine | inflammatory substance produced during allergic reations |
| connective tissue cell found in liver | kupffer cells |
| kupffer cells are part of the | digestive system and reticuloendthelial system |
| plasma cells | produce antibodies to protect from infection |
| two types of connective fibers | fibrous & amorphous |
| fibrous fibers are responsible for | producing intercellular material |
| non-living tissue is | intercellular material |
| monst abundant type of tissue by weight | intercellular material |
| function of intercellular materials is | to bind other organs together |
| function of intercellular material is | provide support & protection |
| function of intercelluar material is | fill spaces and store fat |
| function of intercelluar material is | produce blood cells, fight against infection, help repair tissue damage |
| collagen fibers are made up of what protein | collagen |
| most common protein in the body is | collagen |
| thick and extremely tough fiber is | collagen |
| fiber that resist pulling but is flexiable is | collagen |
| another name for collagen fiber is | white fiber |
| collagen fiber | forms bundles that are crossed or interlaced but not branched |
| collagen | holds ligaments together |
| ligaments | connect bone to bone |
| tendons connect | muscle to bone |
| collagen fibers are found in | skin/dermis, around nerves and muscles/tendons |
| elastic fibers are | yellow fibers |
| elastic fibers consist of | elastin protein |
| elastic fibers help with | stretching and consticting blood vessels |
| a function of elastic fibers is to | control blood pressure |
| if you loose elastic fibers | blood pressure will go up |
| arterosclerosis is | high blood pressure |
| function of elastin is to | permit connective tissue to be stretched and returned to orginial shape |
| vasodilation is | vessels expanding/lowering blood pressure |
| vasoconstriction is | blood vessels are constricted and less blood gets to skin, increasing blood pressure |
| elastic fibers are found | primarily in blood vessels and skin |
| elastic fibers are also found in | vocal cords, air passages of repiratory tract |
