Chronotropic Effect Lab Report
Observations made that constituted a positive (+) for inotropic effect were signs of increased force in regards to the heart muscle contracting. Likewise, a negative (-) inotropic effect was noted for signs of less forceful contractions of the pig heart. A positive chronotropic effect was denoted by an increase in heart rate, and conversely a negative chronotropic effect was observed by a decrease in overall heart rate shortly after the drugs were administered.
Discussion:
The results obtained from the drugs added directly to the heart of the pig were exactly as expected going into this experiment. When epinephrine was applied it increased both the inotropic and chronotropic qualities of the heart similar to how the sympathetic nervous

    Daphnia Lab Report

    The following study was conducted in order to determine the effects of four different pharmaceutical compounds on the heart rate of Daphnia specimens. After basal heart rate was observed and computed, four different solutions each containing either an adrenergic, muscarinic, or nicotinic agonist or antagonist was tested against individual Daphnia. Observations were made through a compound light microscope through the 10x objective. It was found that nicotine decreased, caffeine increased, lidocaine decreased, epi decreased basal heart rate. This can be explained secondary to their effects as either receptor antagonists or agonists.…

    Beta Blocker in Case of Heart Failure

    Beta-blockers block beta-adrenergic substances, such as apinephrine (adrenaline) in the autonomic nervous system (involuntary nervous system). They slow down the heart beat, decrease the force of the contractions of the heart muscles, and reduce blood vessel contraction in the heart, brain, as well as the rest of the body.…

    Lab 13 Daphnia Lab Report

    The purpose of lab number thirteen was to examine the response of the daphnia to a chemical stimulant. Also examined was how human resting heart rates differed from the daphnia’s. Stimulants are any substances that raise the levels of activity in the body. Stimulants could be a number of things such as physical or chemical. Physical stimulus usually deal with something that affects the five senses such as sight, hearing these could be attributed to loud noises or too much light going into your eye. Chemical stimuli differ because chemicals such as caffeine and alcohol usually cause these to affect cognitive abilities and heart rate. These same things can also affect muscle response and glandular response causing twitches and the production…

    Daphnia Experiment

    In this laboratory experiment, our control was the Daphnia that gets spring water, whereas the drugs were the independent variable and the heart rate was the dependable variable. The first step our group did was to place the Daphnia into a clean depression slide. Next, we added a small drop of the spring water and put a cover slip over the slide. Then, we waited for one minute prior to placing the slide on the microscope in order to allow time for either solution or the drug to take its effect. After we put the slide on the microscope, we located the heart of Daphnia and counted its heartbeats while the other member kept time for each three 10-second trials. We recorded our data and calculated the average heart rates of three trials we found during the experiment. Afterwards, we calculated the average 60-second heart rates by multiplying the averages of our 10-second heart rates by 6. These procedures were repeated with the rest of solutions as well, including caffeine, aspirin, alcohol, sleep-aid, and…

    This occurs after feeding, during sleep, and during breath-holding and swimming underwater. A slowed heart rate and the associated fall in the rate of ejection of blood from the heart is sufficient to maintain body function during rest, and conserves energy in the heart under conditions where its supply (and the supply of oxygen in the blood) are diminished. A drug that slows heart rate is called a negative chronotrope and this is demonstrated in this experiment where acetylcholine is used to slow the rate of the Daphnia's…

    Caffeine is a stimulant. It will work by causing the nervous system to work faster. Also, it will cause the blood vessels to constrict. (LaFave, 2003) These effects will work together to increase an animals heart rate. Under normal circumstances, the heart rate will increase as more caffeine is added. At some point the high concentration of caffeine will cause the heart to stop functioning.…

    In this experiment we were examining the effect of caffeine on the heart rate of Daphnia which are water fleas. In my opinion I think that the caffeine will affect the heart rate because when the caffeine enters your blood from the stomach and small intestine it begins to stimulate your central nervous system, the Caffeine stimulates receptors in the cells of your heart to increase your heart rate. The increase of this heart rate speeds up your blood flow as well as increase in blood sugar, urination and blood sugar. So, considering that you can see the through the transparent fleas after dropping the caffeine on them you will witness the hearts beat as a greater haste than usual. So, I will experiment this hypothesis by placing Daphnia under a microscope and recording the heartbeats before pouring the caffeine and after pouring the caffeine.…

    The solutions had no affect on pulsation rate because of the negative change in rate of beats per minute (table 1.1). The alternative hypothesis is supported by the data found in the experiment sample. However there is an error due to the sample size is not large enough to apply to the population of blackworms. Overall there were no significant in the changes of pulsation rates that would conclude that the drugs had an affect. The graph’s 1.3 and 1.4 determine there was no affect on the pulsation rates.…

    In “Introduction to Poetry” by Billy Collins, the major theme portrayed is that, poetry is something to be experienced. Very often, readers will just go through the poem once and will then assume to figure out the underlying meaning. However, this is not true in Collins’ eyes. Collins believes that you need to be patient with poetry and he tells you this through a series of metaphors.…
