Imagery is used fairly often in the eastern coast of Canada may have an unforgiving and rather harsh streak‚ but many Canadians choose to raise their families and practice their craft there. In both short stories by Alistair McLeod; The Lost Salt Gift of Blood and The Boat‚ the setting of the Canadian east coast is used to develop both the plot and the character. Along with the narration of the physical setting there is also the intricate dialogue spoken by the various characters. In combination‚

Period____ Tissues Lab Directions: This lab is broken down into three sections: Epithelial Tissue‚ Connective Tissue‚ and Muscle & Nerve Tissue. For each section‚ read the background and answer any questions before you come to class‚ then in class sketch the specimens listed under each sketch circle. For your sketches‚ include the total magnification under which you viewed the specimen and be very detailed in your sketch. Epithelial Tissue Background Functions of Epithelium Epithelium has two

As well as be able to identify the vessels involved in coronry circulation. Safety will include wearing goggles and apron to prevent any splatter. Exercise 1: ( Slide) Questions: A. Where are some unique structral features of cardiac muscle? - presence of irregularly-spaced dark bands between myocytes (intercalated discs) These allow free flow of action potentials between cells that create muscle contraction. B. What are intercalated discs and what do they do? - Specialized junctions

result show that the flux values increased linearly with TMP as well as sodium ion rejection. Permeate flux values increased proportionally with the temperature and the later effect was more significant at high pressures. The temperature changing has also influenced the rejection of sodium ion. The minerals content especially NaCl and total dissolved solid (TDS) in the drinking water produced in this research are conforming to the standards of World Health Organization (WHO).

Histology This lab focused on the examination and identification of tissues that make up the organs of the body. The tissues are divided into four main categories: epithelial‚ connective‚ muscle‚ and neuronal. Click on the thumbnail images to see a larger version. All of the photomicrographs were taken using the 40X objective (400X magnification)‚ which is the highest magnification we use in this lab. Other resources include linked web pages on the "Resources" page and the histology tutorial

Epithelial tissue protects your body from moisture loss‚ bacteria‚ and internal injury. There are two kinds of epithelial tissues: Covering and lining epithelium covers or lines almost all of your internal and external body surfaces; for example‚ the outermost layer of your skin and other organs‚ and the internal surface lining of your lymph vessels and digestive tract. Glandular epithelium secretes hormones or other products such as stomach acid‚ sweat‚ saliva‚ and milk. Connective tissue generally
