Distinguish among the four tissue types found in the human organic structure. Supply an illustration of each type with its map and location. Epithelial tissue covers the organic structure surface and forms the liner for most internal pits. The major map of epithelial tissue includes protection. secernment. soaking up. and filtration. The tegument is an organ made up of epithelial tissue which protects the organic structure from soil. dust. bacteriums and other bugs that may be harmful. Cells of the epithelial tissue have different forms as shown on the student’s worksheet. Cells can be thin. level to cubic to stretch.
Connective tissue is the most abundant and the most widely distributed of the tissues. Connective tissues execute a assortment of maps including support and protection. The undermentioned tissues are found in the human organic structure. ordinary loose connective tissue. fat tissue. dense hempen tissue. gristle. bone. blood. and lymph. which are all considered connective tissue.

There are three types of musculus tissue: skeletal. smooth. and cardiac. Skeletal musculus is a voluntary type of musculus tissue that is used in the contraction of skeletal parts. Smooth musculus is found in the walls of internal variety meats and blood vass. It is an nonvoluntary type. The cardiac musculus is found merely in the walls of the bosom and is nonvoluntary in nature.
Nerve tissue is composed of specialised cells which non merely receive stimulations but besides conduct urges to and from all parts of the organic structure. Nerve cells or nerve cells are long and string-like. Distinguish among five different types of connective tissue with illustrations of maps and location within the organic structure. Adipose fatty tissue ; type of loose connective tissue that shops energy. insulates and shock absorbers the organic structure Fibrous Tissue composed of packages of collagenic white fibres between which are rows of connective tissue cells. Bone tissue Most stiff connective tissue. internally supports organic structure constructions. really active tissue. heals much more quickly than gristle gristle tissue Dense. flexible tissue similar to cram tissue blood tissue
Consists of blood cells surrounded by nonliving fluid matrix called plasma. Funcion: conveyance vehicle for cardiovascular system. transporting foods. wastes. respiratory gases. and many other bombers thru organic structure hematopoietic tissue Produces blood cells that are added to the go arounding blood. removes worn out blood cells from the blood watercourse. ruddy bone marrow. lymphatic tissue. yellow bone marrow Analyze five different types of epithelial tissue with illustrations of maps and location within the organic structure. Simple squamous-single bed of thin. level. multilateral cells each with a cardinal karyon. It lines internal pits. the bosom and all the blood vass. Besides lines parts of the urinary. respiratory. and male generative piece of lands.
Graded squamous-consists of many beds of cells. Innermost bed produces cells that are first cuboidal or columnar in form. but as cells push toward the surface. they become planate and get down to roll up a protein called ceratin and finally decease. Keratin makes the outer bed of epidermis tough. protective. and able to drive H2O. The liners of the oral cavity. pharynx. anal canal. and vagina are illustrations of graded epithelial tissue. The outermost bed of cells environing the pit remains soft. moist. and alive.
Simple cuboidal-single bed of cubelike cells. each with a cardinal karyon. Found in tubules of the kidney and in the canals of many secretory organs. where it has a protective map. It besides occurs in the secretory parts of some secretory organs. where the tissue produces and releases secernments.
Simple columnar-single bed of tall. cylindrical cells. each with a karyon near the base. This tissue. which lines the digestive piece of land from the tummy to the anus. protects. secretes. and allows soaking up of foods.
Pseudo stratified ciliated columnar-appears to be layered. though really all cells touch the cellar membrane. Many cilia are located on the free terminal of each cell. In the human windpipe. the cilia wave back and Forth. traveling mucous secretion and debris up toward the pharynx so that it can non come in the lungs. Smoking destroys these cilia. but they will turn back if smoke is discontinued.
