The Effects of Ethanol and Nicotine on the Cardio Vascular System in Lumbriculus Variegatus

The effects of fermentation alcohol and nicotine on the cardio vascular system in Lumbriculus variegatus Introduction: The importance of the circulatory system was first suggested by William Harvey in 1628. In this experiment the effects of drugs on the cardio vascular system will be seeed and studied specifically on the pulsation rate. The role of the cardio vascular system is the distribution of oxygen, nutrients and resources, as well as the removal of waste products, plastered factors that walk out these processes may be various gases, chemicals consumed may psychological upset the ph or interfere with other physiological processes, undisputable chemicals may stimulate or inhibit physiology in an organism. The psychometric test subject that will undergo treatment is the blackworm Lumbriculus variegatus, blackworms are suitable because of the visibility of pulse through their transparent skin, the pulse is uphold under the microscope travelling from tail to head in the abaxial blood vessel blackworms are low maintenance organisms, graven image to use in the laboratory and finally are easier to treat, by just exposing them to chemicals they undergo changes with physiological functions (as opposed to mice that need to be inhaled, fed or injected with treatments).

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 & adenosine monophosphate; penetrative 2011). The chemicals chosen as the treatment is ethanol and nicotine, it is false that ethanol will slow the pulse rate in th! e cardio vascular system and that nicotine will speed it up, because of these stimulant and somniferous nature. Materials & vitamin A; Method: * Blackworms Lumbricalis variegates (35) * Petri dishes (8) * Pipettes (8) * Paper towel * Recovery bowl * Microscope * stop watch * Slides preferably with a well * Ethanol - concentrations of 0.5M, 0.1M, 1M * Nicotine ...If you want to get in a safe essay, order it on our website: BestEssayCheap.com
