Physical laws & the environment constrain the size & shape of organisms. 2. Form & function are correlated at all levels of organization. 3. Chemical energy in food is used to sustain form & function. 4. Many animals (& other organisms) regulate

Content (Digestive System) Group No.4 Submitted By: Castro‚Cendrix Paolo‚Christian Tolentino‚Athea Submitted to: Prof.Josephine Tondo Faculty-in-charge I.Description of the system Your digestive system is uniquely constructed to perform its specialized function of turning food into energy. Each step in digestion requires energy‚ and thus imposes an “overhead charge” on the energy made available from absorbed substances The major part of digestion takes place in the

B. submucosa: site of glands‚ blood vessels‚ lymph vessels and nerve plexuses. C. muscularis: circular and longitudinal muscles for propulsion and mixing. D. serosa: serous membrane to reduce friction with movement. 2. Where along the GI tract is the muscularis composed of skeletal tissue? Is control of this skeletal muscle‚ voluntary

recombinant T-Rp3 was expressed in E. coli BL21 (DE3) as previously described (Favaro et al.‚ 2014) and purified by a single step His-based affinity chromatography in an ÄKTA purifier FPLC (GE Healthcare). Protein was then dialyzed against 50 mM MES buffer (pH 6‚0) overnight at room temperature‚ frozen in liquid nitrogen and stored at -80 ˚C after 0.22 μm pore membrane filtration. Evaluation of DNA-protein interaction by gel retardation assay Protein-DNA complexes were formed using 1 µg of plasmid pTriEx-1

were treated the sialic acid lectins SNA I‚ WGA‚ MAL and HAA to confirm the presence of sialic acid carbohydrates in the cell surface membranes of these strains. This was done by using two sets of samples-one treated with trypsin and the other without. The sample treated with trypsin showed agglutination for all lectins while the untreated sample showed little to no agglutination. A control was also used with the cells being incubated with buffer instead of lectins. The lectin pattern of agglutination

The mucus coats the food‚ and reduces friction making swallowing easier. The continuous flow of saliva also flushes and cleans the oral surfaces while controlling oral bacteria through salivary antibodies. The pH of saliva during meal time rises from slightly acidic pH 6.7 to more alkaline pH 7.5. Radiation and emotional distress can cause a reduction of salivary secretions. This then can create an unhealthy oral cavity environment due to increased bacteria population. Over time‚ the complications

nasopharynx from the mouth Parotid gland • Secretes saliva (amylase enzyme) which breaks down starches into sugar Stomach • Stores food • Begins digestion of tissues and proteins by secretion of gastric juices. These juices are very acidic (pH 1-2). The semi-digested stomach contents are called chyme Esophagus • Transports food from the mouth to the stomach. Waves of involuntary muscle contraction (peristalsis) push food down the esophagus Pylorus • A muscle that regulates the
