1  Tissues are groups of cells similar in structure and function Epithelial Tissue, Connective Tissue,

2  Epithelial tissue is composed almost entirely of cells.  It is supported by connective tissue, reticular, and basal laminae.  It is Avasular but innervated, contains no blood vessels but supported by nerve fibers Tissue, Simple EpithelialTissue, Simple Epithelial, Stratified Epithelial, Transitional EpithelialStratified Epithelial, Transitional Epithelial

3  Simple Epithelia are single layered cells  It is usually located in places where there is lots of absorption and filtration. TissueTissue, Epithelial Tissue,Epithelial Tissue, Simple Squamous, Cuboidal, Columnar

4  In Simple Squamous the cells appear to be flattened.  Also found where filtration occurs, for example in the kidneys or lungs. TissueTissue, Simple EpithelialSimple Epithelial

5  Simple Cuboidal has a nucleus in the shape of a sphere and is a single layer of cells.  It is important because it secretes and absorbs. TissueTissue, Simple EpithelialSimple Epithelial

6  Single layer of tall cells that are tightly packed in together.  Absorbs and secretes and is used in the lining of the digestive tract in the stomach.  Lined with cilia to move substances through the passageways. TissueTissue, Simple Epithelial TissueSimple Epithelial Tissue

7  These cells often vary in height.  Because the heights vary, it gives off fake (pseudo) looking layers.  Secretes and absorbs along the lungs. Tissues, Simple Epithelial

8  Major role in these cells are protection  Two or more cells that divide and regenerate, to replace the older more worn surface of cells Tissue, Epithelial, Simple SquamousTissue, Epithelial, Simple Squamous, Cuboidal, ColumnarCuboidalColumnar

9  Stratifies Squamous has many different layers.  Usually found in places that are more likely to tear  It is used for protection Tissue, Stratified Epithelial

10  Very rare in the human body  They are sometimes found in ducts and in larger glands such as sweat glands and mammary glands. TissueTissue, Stratified EpithelialStratified Epithelial

11  Can be found in the lining of glandular ducts, pharynx, and the male urethra.  Occurs as transitional areas between other types of epithelia Tissues, Stratified Epithelial

12  Its basal layer is cuboidal and columnar.  It is found in the urinary organs and stretches as urine is produced.  When urine is present it stretches from six layers to about three. TissueTissue, Epithelial TissueEpithelial Tissue

13  This type of tissue is very common in the body.  There are many different forms of connective tissue and it does way more than just connect body parts. Tissues, Connective Tissue Proper Cartilage, BloodBlood, Bone, Connective Tissue Proper Loose,Bone,Connective Tissue Proper Loose, Dense

14  Connective tissue is located all among the body.  It is used to connect muscle to muscle, bone to bone, and muscle to bone. TissueTissue, Connective Tissue,Connective Tissue Hyaline CartilageHyaline Cartilage, Elastic Cartilage, FibrocartilageElastic CartilageFibrocartilage

15  Hyaline Cartilage is the most abundant in the body.  Provides firm support  It covers long ends on bones and provides compression on joints. Tissue, Connective Tissue Proper

16  Very similar to Hyaline Cartilage.  There are more elastic fibers  It has a great amount of strength and flexibility Tissue, Connective Tissue Proper

17  It is similar to hyaline cartilage, and dense regular connective tissues.  It is compressible and has tension resistency  Located where heavy amounts of pressure are required. Tissue, Connective Tissue, Fibrocartilage

18  Surrounded my a nonliving fluid called blood plasma.  Blood carries out functions such as carrying nutrients, wastes, respiratory gases and other substances throughout our bodies. TissueTissue, Connective TissueConnective Tissue

19  A connective tissue that forms the Skeleton  Hard and calcifies matrix with collagen fibers found in bone.  Supports, protects, and provides levers for muscular action. TissueTissue, Connective TissueConnective Tissue

20  Classified as an areolar connective tissue  Is gel like and wraps around as well as cushions organs.  It is widely distributed thoroughout the body. Tissue, Connective TissueTissue, Connective Tissue, Loose AdiposeLoose Adipose, ReticularReticular

21  Reserves food stores, insulates against heat loss, and supports and protects.  Found under skin, around kindeys, within the abdomen, and in breasts. Tissue, Loose Connective Tissue

22  Forms a soft internal skeleton that support other cell types.  Found in lymph nodes, bone marrow, and in the spleen. TissueTissue, Loose Connective TissueLoose Connective Tissue

23  Fibroblasts are the major cell type.  Found in tendons, ligaments, and aponeuroses.  Attaches muscle to muscle, muscle to bone, and bone to bone. Tissue, ConnectiveTissue, Connective, Dense Regular, Dense IrregularDense RegularDense Irregular

24  Has parallel collagen and cell type is fibroblasts TissueTissue, Dense Connective TissueDense Connective Tissue

25  Can withstand tension in many directions  Irregularly arranged collagen fibers  Major cell type is fibroblasts TissuesTissues, Dense Connective TissueDense Connective Tissue

26  Fast acting control system  It triggers muscle contraction as well as gland secretion. Tissues

27  Highly cellular  Responsible for most body movements  Highly vascularized Tissue, SkeletalTissue, Skeletal, Cardiac, SmoothCardiac, Smooth

28  Attached by the bones of the skeleton.  This muscle forms skin and flesh, and is responsible for bodily movements. Tissue, Muscle Tissue

29  Only found on the wall of the heart.  When is contracts it helps flow blood to the heart.  Cardiac cell muscles are striated. TissueTissue, Muscle TissueMuscle Tissue

30  Called Smooth muscle because its cells have to visible striations.  Spindle shaped and contain a nucleus in the center.  It acts to squeeze substances through organs by contracting and relaxing. Tissue, Muscle Tissue
