Tissues are groups of cells similar in structure and function Epithelial Tissue, Connective Tissue, 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 Epithelial, Stratified Epithelial, Transitional Epithelial Simple Epithelia are single layered cells It is usually located in places where there is lots of absorption and filtration. Tissue, Epithelial Tissue, Simple Squamous, Cuboidal, Columnar In Simple Squamous the cells appear to be flattened. Also found where filtration occurs, for example in the kidneys or lungs. Tissue, Simple Epithelial 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. Tissue, Simple Epithelial 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. Tissue, Simple Epithelial Tissue 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 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 Squamous, Cuboidal, Columnar Stratifies Squamous has many different layers. Usually found in places that are more likely to tear It is used for protection Tissue, Stratified Epithelial Very rare in the human body They are sometimes found in ducts and in larger glands such as sweat glands and mammary glands. Tissue, Stratified Epithelial 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 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. Tissue, Epithelial Tissue 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, Blood, Bone, Connective Tissue Proper Loose, Dense Connective tissue is located all among the body. It is used to connect muscle to muscle, bone to bone, and muscle to bone. Tissue, Connective Tissue, Hyaline Cartilage, Elastic Cartilage, Fibrocartilage 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 Very similar to Hyaline Cartilage. There are more elastic fibers It has a great amount of strength and flexibility Tissue, Connective Tissue Proper 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 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. Tissue, Connective Tissue 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. Tissue, Connective Tissue 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 Tissue, Loose Adipose, Reticular 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 Forms a soft internal skeleton that support other cell types. Found in lymph nodes, bone marrow, and in the spleen. Tissue, Loose Connective Tissue Fibroblasts are the major cell type. Found in tendons , ligaments, and aponeuroses. Attaches muscle to muscle, muscle to bone, and bone to bone. Tissue, Connective, Dense Regular, Dense Irregular Has parallel collagen and cell type is fibroblasts Tissue, Dense Connective Tissue Can withstand tension in many directions Irregularly arranged collagen fibers Major cell type is fibroblasts Tissues, Dense Connective Tissue Fast acting control system It triggers muscle contraction as well as gland secretion. Tissues Highly cellular Responsible for most body movements Highly vascularized Tissue, Skeletal , Cardiac, Smooth Attached by the bones of the skeleton. This muscle forms skin and flesh, and is responsible for bodily movements. Tissue, Muscle Tissue Only found on the wall of the heart. When is contracts it helps flow blood to the heart. Cardiac cell muscles are striated. Tissue, Muscle Tissue 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.
