Question

In Chapter 5, our Rizzo Anatomy & Physiology textbook describes the 4 main tissue types: epithelial, connective, muscle, and nervous. Chapter 5 also gives examples, with detailed diagrams and descriptions, of each tissue type. Choose one example and describe how its size, shape and structure allow it to perform its functions. Also, describe how a weakness or failure in some part of your example's size, shape or structure would harm the tissue's ability to perform its function(s). There should be enough information in Chapter 5 of the Rizzo e-textbook, but if you wish to consult outside scientific sources that is acceptable.

Answer 1

1.epithelial tissue - they are spread all over the body they form the covering of the body surfaces ,internal organs and various internal surface of the body.tissue is made up of densely packed cell.

Function-the main function of epithelial tissue is secretion, absorption, protection,and sensation.

*Protection- skin provide us protection skin is made up of epotepithe tissue.

*Absorption- the function of absorption is function by epithelial tissue is digestive system or tract,the nutrition is absorb by cell lining.

*Secretion- the function of secretion is carried out in kidney in tubule cells, where the blood is purified and toxic material is secretion out side the body.

*Sensation- the sensors neurons passes the information which the help of epithelial tissues.

The abnormal function of epithelial tissue leads to pre cancerous changes,skin diseases and HPV ( sexual transmitted infection).
