Why is the skin scrutinized? The scrutinized skin protects the body from 70% of all infectious bacteria and viruses it touches. Exercise 2: The Microscopic Structure of Mucous Draw and describe the structures you observed of the following slides: A. Sequestration’s ciliated columnar epithelium of the trachea B. C. Stratified exogamous epithelium (non-scrutinized) of the esophagi Simple columnar epithelium (duodena um) of the small intestine A.
Compare and contrast the roles of the three mucous membranes.Mucous membranes are composed of epithelial cells lying on top of loose connective tissues. Serous membranes are epithelial cells that are attached to a small amount of areola connective tissues. These membranes are unique because they occur in two layers. Synopsis membranes are imposed entirely of connective tissue and are found lining the cavities around the joints.
These membranes help provide a smooth surface for the movement of joints. B. What is the role of mucous in the body? To essentially protect our bodies from invasions.Exercise 3: Observing Synopsis Membrane Observations Data Table 1: Observing Synopsis Membrane Tissue Types (epithelial/ I Membrane I connective) Functions Skin Epithelial, connective Coetaneous Common Location I Epithelial, connective Secretion of oil & sweat I Lining of digestive, respiratory & I Secretion of mucus, absorption I originate tracts I I Mucous I Epithelial, connective I Lining of close ventral body cavities I Secretion of serous fluid, I Serous decreases friction Connective Lining of joint cavities of freely I Secretes synopsis fluid, decreases I movable joints friction I Synopsis A.What is the function of the synopsis membrane? It helps provide a smooth surface for the movement of joints B. Rheumatoid arthritis results in part from an infection and immune response in the synopsis membrane. What effect does this have on the ability of this membrane to carry out its functions? This membrane secretes synopsis fluid, which helps lubricate and educes friction between bones in a joint.
An infection in this membrane results in a not-so-smooth surface for the movement of joints – therefore contributing to the aches, pain and high level of discomfort typically associated with rheumatoid arthritis.C. Complete Data Table 1 under observations. Conclusion Research pleurisy, peritonitis, and periphrastic. What are these conditions and how do they affect homeostasis in the body? Pleurisy- inflammation of the lining of the lungs and chest that leads to chest pain when you take a breath or cough Peritonitis- inflammation of the thin tissues that lines the inner wall of he abdomen and covers most of the abdominal organs.
Usually causes the belly to be very painful and tender.
