In: Anatomy and Physiology
Discuss three specific tissue types. Give location and function in the human body.
There are four types of specific tissues in human body.
1. epithelial
2. connective
3. nervous
4. muscle.

FUNCTIONS |
Epithelial |
· Simple squamous epithelium · Simple cuboidal epithelium · Simple columnar epithelium · Pseudo -stratified columnar epithelium · Stratified squamous · Stratified cuboidal · Stratified columnar · Transitional epithelium |
· Air sacs of lungs and the lining of the heart, blood vessels and lymphatic vessels · Ducts and secretory portions of glands and kidney · Bronchi, uterine tubes, uterus, bladder · Ciliated tissues, trachea, upper respiratory tract · Lines of oesophagus, mouth and vag*na · Sweat glands, salivary glands, mammary glands · Male urethra, ducts of some glands · Lines of bladder, urethra and ureter |
· Allows materials to pass through by diffusion, filtration lubrication · Secretes and absorbs · Secretes mucous and enzyme · Secretes mucous, ciliated tissues moves mucous · Protects against abrasion · Protective tissues · Secretes and protects · Allows urinary organs to expands and stretch |
connective |
· Loose connective tissue · Dense connective tissues · Adipose tissues · Blood · Cartilage · Bone |
· Fibroblasts, adipose and WBCs · Fibroblasts · Adipocytes · RBCs and WBCs & platelets · Chondrocytes · Osteocytes, osteoblasts |
· Defends the body against antigens · Makes plasma · Oxygen transportation · Preserve fats and heat in body · Makes skeleton · Preserve calcium |
nervous |
Neurons |
Brain, spinal cord and nerves throughout the body |
Electrochemical signalling throughout the body, functions of brain body connections, voluntary and involuntary actions |
muscle |
· Skeletal · Smooth · Cardiac |
· Attached to bones · Internal and hollow organs · Heart |
· Pull bones and make them move (voluntary) · Move the food, urine etc (involuntary) · Pumps blood and contraction of heart (involuntary) |
