Phenylalanine also disrupts amino acid metabolism, hormonal equilibrium, and nerve functions. Aspartic acid is believed to function as an excitatory neurotransmitter in the central nervous system (CNS). Methanol gets converted to formate, it is either excreted or it gets accumulated in the body to form formaldehyde, diketopiperazine (a carcinogen), and other potent toxic products.

b) Halons are a group of chemical compounds with one or more halogens linked making them a type of organic halide. Halons were key ingredients to certain aerosol sprays such as deodorant and hair spray. The elimination caused manufacturers to alter the chemical makeup of the sprays, and quite frankly turned me to using solid deodorant as opposed to aerosol sprays. c) Carbon tetrachloride is one of the most potent hepatotoxins, meaning it is very harmful to the liver. This compound was once used as a pesticide for killing insects in stored grain.
Lumbricalis variegates cardio vascular system has a myogenic nature(myogenic-depolarisation impulses for heartbeats originating in muscle cells), the dorsal and ventral blood vessels have peristaltic pumps (Halfmann & Crisp 2011). The chemicals chosen as the treatment is ethanol and nicotine, it is assumed that ethanol will slow the pulse rate in the cardio vascular system and that nicotine will speed it up, because of these stimulant and depressant nature. Materials & Method: * Blackworms Lumbricalis variegates (35) * Petri dishes (8) * Pipettes (8) * Paper towel * Recovery bowl * Microscope * Stopwatch * Slides
When the body detects stress, the SNS is activated which leads to raised heart rate, which leads to higher blood pressure which can lead to Chronic Heart Disease, heart attack, stroke etc. The Beta Blocker is taken then and it acts by reducing activity of adrenaline and noradrenaline and also binds to the receptors of the heart and other areas of the body stimulated by arousal. As a result of blocking these receptors, it is therefore harder to stimulate them and so the heart beat is slowed, and therefore lower blood pressure. A strength of drug treatment is that they are proven to be affective, for example Kahn et al tested 250 participants over 8 weeks, and found that BZs were better than a placebo. The drugs are also very quick and easy to use, and do not require extra effort or stress that could be incurred using other, longer methods of stress management.
Andre’ Dorsey Mrs. B Lab section: Alka-seltzer Experiment In this experiment we wanted to see what would dissolve the Alka-Seltzer the quickest using these three beverages: orange juice, milk, and water. Alka-Seltzer is a pain reliever for minor aches, pains, fever, headache, heartburn, indigestion, and hangovers. What I think about the experiment is that the orange juice would dissolve the Alka-Seltzer the fastest out of the three beverages because it is a acid. The materials used for this is experiment were: beaker a constant, Alka-Seltzer a dependent variable, stop watch a constant, 100ml of water a dependent variable and also a controlled group, orange juice independent variable, and milk independent variable. Procedures for
That is why we are more susceptible to infections. The stress hormone corticosteroid can suppress the effectiveness of the immune system (e.g. lowers the number of lymphocytes). Stress can also have an indirect effect on the immune system as a person may use unhealthy behavioral coping strategies to reduce their stress, such as drinking and smoking. Stress is linked to: headaches; infectious illness (e.g.
Antidepressants e.g. Cipramil Antidepressants work by changing the chemical balance in the brain and that can in turn change the psychological state of the mind such as for depression. Common side effects include: blurred vision, dizziness, drowsiness, increased appetite, nausea, restlessness, shaking or trembling, and difficulty sleeping. Other side effects include: dry mouth, constipation, and sweating. 2. drugs like insulin (blood has to be taken from a pinprick so that glucose can be measured before the insulin can be given), warfarin to thin the blood - again blood levels must be checked regularly, dioxin to
1. The MMR vaccination is an immunization against measles, mumps and rubella. That is administrated via injection. 2. We vaccinate against measles, mumps and rubella because they are very unpleasant illnesses and either one of them could cause a death.
B) The involuntary muscle process initiated by deglutition of water which may cause Chloe pain, swallowing would be the involuntary muscle process. By swallowing it contracts the pharyngeal muscles which sets peristalsis, it begins with coordinated contractions and relaxation of muscles in the esophagus and into the stomach (Jenkins, 2010 Pg.788). C) The reason that reducing Chloe’s stomach size would reduce her acid reflux because of her bypass surgery which reduced her stomach size which now empties quicker because of the reduction of the duodenum where most of the churning takes place with digestive enzymes, that could force the sphincter to emit the reflux (Jenkins, 2010 Pg. 794). D) The protein digestion will be affected by Chloe’s surgery because the proteins will be flushed out of the body at a faster rate.
