2.1. Test Procedure Before data was analyzed, the Easy Pulse circuit had to be tuned to the team members’ specific pulse in order to produce transparent and accurate data. This is due to the fact that each individual person has relatively unique heart rates and pulse strengths. While the A0 pin on the circuit board was connected to the AI0+ channel on the Elvis board, P1 or the Gain was turned completely clockwise using a screwdriver. From there, P1 was rotated clockwise until the peak of each pulse were relatively close to 5V. Once tuned, data on the pulse signal was acquired and analyzed using the program Pulse Monitor.vi.…
Adrenal medulla:- The adrenal medulla produces the hormones epinephrine and norepinephrine under stimulation by the sympathetic division of the autonomic nervous system. Both of these hormones help to increase the flow of blood to the brain and muscles to improve the “fight-or-flight” response to stress. These hormones also work to increase heart rate, breathing rate, breathing rate, and blood pressure while decreasing the flow of blood to and function of organs that are not involved in responding to emergencies.…
Although numerous influences modulate cardiac function, research has shown that this function is largely influenced by the ANS. More specifically, when the SNS is activated…
The independent variable in this experiment is appearance of the red square, and be able to respond fast as possible. This was measured by valid, neutral, and invalid.…
Certain chemicals and agents effect the heart's rate and contraction. Unlike skeletal muscle, the heart muscle depolarizes automatically when external stimuli are not present. This is called automaticity, which happens when the plasma membranes in heart muscle cells allow sodium to leak into the cell at a faster rate than potassium is moving across the membrane (book). The sodium moving inside the cell causes it to progressively…
Introduction The purpose of the lab was to see the effects of heart rate and blood pressure when 3 male and 3 female students exercised compared to when they were at rest. My hypothesis is that the data from the exercise part of the experiment will cause both the heart rate and blood pressure (systolic and diastolic) to increase more than the resting state.…
When the body is at rest, the heart beats at a normal pace. As kinetic energy is applied to the body, it is put into work which can make the heart rate increase a bit. Speed requires kinetic energy in order for it to be done. Depending on how fast the speed being applied to the body, the harder the body will work affecting the cardiovascular and respiratory systems. Elements like force, friction and mass also play a huge role in this experiment.…
Question 1. a) “What serosal cavities have been penetrated by the 1st arrow?” The pleural cavity and pericardial cavity have been penetrated by the 1st arrow as they tend to appear in the thoracic cavity on the left side of the chest. b) “Explain the location, the microscopic characteristics of the serous membrane, and the purpose of the serous membrane.”…
However not all responses created the same amount of heart acceleration. An example would be while showing the clips from the horror movie The Woman in Black the audience gave both physical reactions such as jumping and audio responses like screams. The subjects who gave a physical reactions heart rate was much slower than those who jumped out of their seat. Another observation was when asked what their favorite of the movies shown was 75% of the subjects said action. Action in testing gave the lowest score, however got highest in popularity.…
The heart rate increases immediately after the subject was immersed in cold water. Within 2-3 seconds in cold water we expect to detect tachycardia (Tipton, 1989). During our experiment, our subjects heart rate increased by a huge 35bpm from our basal reading whole body immersion, which was to be expected. This was due to an increase in sympathetic drive, subsequently causing vasoconstriction of the periphery from the release of norepinephrine (Croft et al., 2013; Silverthorn & Michael, 2013). Vasoconstriction of the peripheral following cold water submersion commands the blood to flow to centrally ultimately to ensure the body’s vital organs remain within a homeostatic range.…
The lab that is being conducted is a controlled experiment. The controlled variables included the gender, which was female, the age, which was young girls (17-18), their athletic ability, which was none, and their health, which the subjects were not sick or had any illness or disease. None of the test subjects consumed alcohol, therefore their reaction times were not impaired All test subjects were having a good day, so emotions such as grief, anger did not affect their reaction time I made sure to tell my test subjects the day before to get enough sleep, and to not consume caffeine. o Qualitative Rulers were light and made of plastic.…
Explain the physiological changes that occur in the cardiovascular and respiratory systems in response to exercise. One of the main physiological changes that occur within the cardiovascular system in response to exercise is heart rate. When engaging in exercise, the amount of energy required increases instantaneously within the skeletal muscles. This sudden demand creates increasing stress on the cardio-respiratory system to remove the waste products and carbon dioxide from the cells and provide more oxygen for the working cells.…
Brain temperature, breathing rate, heart rate, and blood pressure are at their lowest during the 3rd stage of…
The more intense the movie, the more of an increase the heart rate experiences. Further possible investigations include the effect of different techniques in horror movies such as suspense, gore, jump scares, and dark voyeur on heart rate. Another investigation could be the effect of the length of a video clip on heart rate; two-and-a-half minutes may not be enough time for the subject to fully comprehend the scene and react…
Homeostasis can be defined in many ways. The biological definition would be the habit of a cell to control its internal environment and maintain equilibrium or balance. In more simple way it helps bring back everything to its stable state. All the organs in the human body contributes its actions to the homeostasis system to help bring balance to the neural, thermal and chemical factors by working together in a complicated way. And that being said, all of the homeostasis are being controlled by a system called control system which is generally the brain.…
